CHAPTER 1
INTRODUCTION
(Return to table of contents.)
Status
This is the third edition of the Food and Drug Administrations's (FDA) "Fish
and Fishery Products Hazards and Controls Guidance." This Guide relates to
FDA's final regulations (21 CFR 123) that require processors of fish and fishery
products to develop and implement Hazard Analysis Critical Control Point (HACCP)
systems for their operations. Those final regulations were published in the Federal
Register on December 18, 1995 and became effective on December 18, 1997. The
codified portion of the regulations is included in Appendix 8.
FDA intends to revise and reissue this guidance every two to three years as
the state of knowledge advances relative to fish and fishery products hazards
and controls. The agency will accept public comment on this third edition of the
guidance for consideration in drafting the fourth edition. Comments should be
submitted to:
U.S. Food and Drug Administration
Dockets Management Branch (HFA-305)
Room 1-23
12420 Parklawn Drive
Rockville, MD 20857
Comments should be identified with Docket Number 93N-0195.
This guidance is being issued as a companion document to "HACCP: Hazard
Analysis Critical Control Point Training Curriculum," which was developed
by the Seafood HACCP Alliance for Training and Education. The Alliance is an organization
of federal and state regulators, including FDA, academia, and the seafood industry.
FDA encourages processors of fish and fishery products to use the two documents
together in the development of a HACCP system. Copies of the training document
may be obtained from:

Purpose
The primary purpose of this guidance is to assist processors of fish and fishery
products in the development of their HACCP plans. Processors of fish and fishery
products will find information in this guidance that will help them identify hazards
that are associated with their products, and help them formulate control strategies.
Another purpose of this guidance is to help consumers and the public generally
to understand commercial seafood safety in terms of hazards and their controls.
This guidance does not specifically address safe handling practices by consumers
or by retail establishments, although many of the concepts contained in this guidance
are applicable to both.
This guidance is also intended to serve as a tool to be used by federal and
State regulatory officials in the evaluation of HACCP plans for fish and fishery
products.
Scope & Limitations
The controls and practices provided in this guidance are recommendations and
guidance to the fish and fishery products industry. This guidance provides information
that would likely result in a HACCP plan that is acceptable to FDA. However, it
is not a binding set of requirements. Processors may choose to use other control
measures, as long as they provide an equivalent level of assurance of safety for
the product. However, processors that chose to use other control measures (e.g.
critical limits) are responsible for scientifically establishing their adequacy.
The information contained in the tables in Chapter 3 and in Steps #10 and 11
in Chapters 4-21 provide guidance for determining which hazards are "reasonably
likely to occur" in particular fish and fishery products under ordinary circumstances.
The tables should not be used separately for this purpose. The tables list potential
hazards for specific species and finished product types. This information must
be combined with the information in the subsequent chapters to determine the likelihood
of occurrence.
This guidance is not a substitute for the performance of a Hazard Analysis
by a processor of fish and fishery products, as required by FDA's regulations.
Hazards not covered by this guidance may be relevant to certain products under
certain circumstances. In particular, processors should be alert to new or emerging
problems (e.g., the occurrence of natural toxins in fish not previously associated
with that toxin).
This guidance covers safety hazards associated with fish and fishery products
only. It does not cover most hazards associated with non-fishery ingredients (e.g.,
Salmonella enteritidis in raw eggs). However, where such hazards are presented
by a fishery product that contains non-fishery ingredients, control must be included
in the HACCP plan. Processors may use the principles included in this guide for
assistance in developing appropriate controls for these hazards. For example,
the hazard of food allergens and food intolerance substances that are part of
or directly added to the food can be controlled using the principles described
in Chapter #19. As a further assistance
in this regard, Appendix 6 provides a list of the most common food allergens that
can pose a health risk to certain sensitive individuals.
This guidance does not cover the hazard associated with the formation of Clostridium
botulinum toxin in low acid canned foods (LACF) or shelf-stable acidified
foods. Mandatory controls for this hazard are contained in the LACF regulation
(21 CFR 113) and the acidified foods regulation (21 CFR 114). Such controls need
not be included in HACCP plans for these products.
This guidance does not cover the sanitation controls required by the Seafood
HACCP regulation. However, the maintenance of a sanitation monitoring program
is an essential prerequisite to the development of a HACCP program. If necessary
sanitation controls are not included in a prerequisite sanitation monitoring program,
they must be included in the HACCP plan. It is the agency's intent to provide
guidance on the development of sanitation standard operating processes and sanitation
monitoring programs in the future.
This guidance does not describe corrective action or verification records,
because these records are not required to be listed in the HACCP plan. Nonetheless,
such records must be maintained, where applicable. Likewise, it does not recount
the specific requirements for the content of records that are set out in §
123.9(a).
This guidance does not cover verification activities such as reassessment of
the HACCP plan and/or the hazard analysis and review of consumer complaints, that
are mandated by § 123.8.
The guidance also does not provide specific guidance to importers of fish and
fishery products for the development of required importer verification procedures.
However, the information contained in the text, and, in particular, in Appendix
5, should prove useful for this purpose. Additionally, it is the agency's intent
to provide more specific guidance for importers, either in future editions of
this guidance, or in a separate guidance document.
Changes in this Edition
Following is a summary of the most significant changes in this edition of the
guidance.
The information contained in Table 3-1 (Potential Vertebrate
Species Related Hazards) is modified as follows:
- Dace (Rhinichthys spp.) is now listed as having a potential pesticides
and environmental contaminants hazard;
- Alewife or river herring (Alosa pseudoharengus) is now listed as having
a potential scombrotoxin (histamine) hazard;
- Wild-caught freshwater salmon (Oncorhynchus spp., Salmo salar)
is no longer listed as having a potential aquaculture drug hazard, an error
in the Second Edition;
- Mackerel (Scomber scombrus) is no longer listed as having a potential
natural toxin (PSP) hazard.
The information contained in Table 3-3 (Potential Process
Related Hazards) is modified as follows:
- Smoked fish is now listed as having a potential C. botulinum hazard
only when it is reduced oxygen packaged and distributed or stored refrigerated;
- A number of products are now listed in Table 3-3 as having potential glass
inclusion hazards;
- Dried fish is now listed as having a potential C. botulinum hazard;
- Fully cooked prepared foods are now listed as having potential pathogen survival
through pasteurization and pathogen contamination after pasteurization hazards.
The recommendations in Chapter 4 for the control of pathogens
from the harvest area are changed as follows for consistency with 1998 and 1999
Interstate Shellfish Sanitation Conference actions:
- Raw consumption warnings on tags of molluscan shellfish shellstock containers
are now recommended only if the shellstock is intended for raw consumption and
the recommended language has been modified;
- Additional information is included about the control of Vibrio parahaemolyticus
in shellstock intended for raw consumption, including information about water
sampling for Vibrio parahaemolyticus performed by Shellfish Control Authorities
under certain conditions;
- Specific controls are now recommended for the control of Vibrio parahaemolyticus
in oyster shellstock intended for raw consumption if the oysters are harvested
in an area which has been confirmed as the original source of oysters associated
with two or more V. parahaemolyticus illnesses in the past three years.
The new control strategy example relies on the following critical limits for the
time from harvest to refrigeration, and is based on the Average Monthly Maximum
Air Temperature (AMMAT):
- For AMMAT of less than 66°F (less than 19°C): 36 hours
- For AMMAT of 66°F to 80°F (19°C to 27°C): 12 hours
- For AMMAT greater than 80°F (greater than 27°C): 10 hours;
- For the control of Vibrio vulnificus, the critical limits recommended
for the time from harvest to refrigeration for shellstock intended for raw consumption,
based on Average Monthly Maximum Water Temperature (AMMWT), are now:
- For AMMWT of less than 65°F (less than18°C): 36 hours
- For AMMWT of 65 to 74°F (18 to 23°C): 14 hours;
- For AMMWT of greater than 74 to 84°F (greater than 23 to 28°C): 12
hours;
- For AMMWT of greater than 84°F (greater than 28°C): 10 hours;
- For the control of pathogens other than Vibrio parahaemolyticus and
Vibrio vulnificus, the critical limits recommended for the time from harvest
to refrigeration for shellstock intended for raw consumption are now:
- For AMMAT of less than 66°F (less than 19°C): 36 hours;
- For AMMAT of 66 to 80°F (19 to 27°C): 24 hours;
- For AMMAT of greater than 80°F (greater than 27°C): 20 hours.
The recommendations in Chapter 4 for the control of pathogens
from the harvest area are additionally changed as follows:
- The information on pathogens in molluscan shellfish is now more clearly divided
into two categories:
- The control of pathogens of human or animal origin;
- The control of naturally occurring pathogens;
- The recommended goal of pasteurization for the control of Vibrio vulnificus
is now more clearly defined as the reduction of the pathogen to nondetectable
levels [i.e., less than 3 MPN/gram, as defined by the National Shellfish Sanitation
Program (NSSP)]
.
The recommendations in Chapter 5 for the control of parasites
are changed as follows:
- The results of a survey of U.S. gastroenterologists on U.S. seafood-borne
parasitic infections are now cited;
- The recommended freezing times/temperatures are now:
- Freezing and storing at -4°F (-20°C) or below for 7 days (total time);
or
- Freezing at -31°F (-35°C) or below until solid and storing at -31°F
(-35°C) or below for 15 hours; or
- Freezing at -31°F (-35°C) or below until solid and storing at -4°F
(-20°C) or below for 24 hours;
- Because of the changes in the recommended critical limits, the recommended
control strategies now refer only to external temperatures during freezing and
to the length of time that the fish is held at the appropriate freezer temperature
or the length of time that the fish is held after it is solid frozen, whichever
is appropriate;
- The parasite hazard is no longer considered reasonably likely to occur if
the finished product is fish eggs that have been removed from the skein and rinsed.
The recommendations in Chapter 6 for the control of natural
toxins are changed as follows:
- PSP in lobster is no longer considered a significant hazard because the levels
found in lobster tomale are not likely to pose a health hazard unless large quantities
are eaten from a heavily contaminated area.
The recommendations in Chapter 7 for the control of scombrotoxin
formation are changed as follows:
- Information is now provided about the salt-tolerant and facultative anaerobic
nature of some of the histamine-forming bacteria, raising concern for scombrotoxin
formation in some salted and smoked fishery products and in fishery products packed
in reduced oxygen environments (e.g. vacuum packaging);
- The on-board chilling recommendations are significantly modified as follows:
- Generally, fish should be placed in ice or in refrigerated seawater or brine
at 40°F (4.4°C) or less within 12 hours of death, or placed in refrigerated
seawater or brine at 50°F (10°C) or less within 9 hours of death;
- Fish exposed to air or water temperatures above 83°F (28.3°C), or
large tuna (i.e., above 20 lbs.) that are eviscerated before on-board chilling,
should be placed in ice (including packing the belly cavity of large tuna with
ice) or in refrigerated seawater or brine at 40°F (4.4°C) or less within
6 hours of death;
- Large tuna (i.e., above 20 lbs.) that are not eviscerated before on-board
chilling should be chilled to an internal temperature of 50°F (10°C) or
less within 6 hours of death;
- It is now recommended that, when refrigerated brine or seawater is used for
chilling fish on the harvest vessel, the temperature of the cooling media be monitored
and recorded (harvest vessel control strategy only);
- It is now recommended that the critical limits at receiving from the harvest
vessel include a requirement that the chilling of fish on the harvest vessel be
continued to bring the internal temperature of the fish to 40°F (4.4°C)
or less (harvest vessel control strategy only);
- It is now recognized that certain data previously expected to be recorded
by the harvester on harvest vessel records may, under certain circumstances, be
more efficiently recorded by the primary (first) processor on receiving records
(harvest vessel control strategy only), such as:
- Method of capture;
- Air and water temperature;
- Method of onboard cooling;
- Estimated date and time of death;
- It is now recognized that, as an alternative to the primary processor receiving
harvest vessel records that are maintained by the vessel operator, certain harvest
operations may lend themselves to monitoring and record keeping entirely by the
primary processor. This arrangement is suitable only if the primary processor
has direct knowledge about those aspects of the harvesting practices that must
be controlled to ensure that the appropriate critical limits are met. For example,
if the harvest vessel leaves from the processor's facility and returns with the
iced or refrigerated catch to the processor's facility within the appropriate
time limits for on board icing or refrigeration of the catch, under certain circumstances
it may be possible for the processor to perform all of the monitoring and record
keeping functions ordinarily performed by the harvester;
- It is now recommended that the critical limits at receiving from the harvest
vessel include a requirement that fish delivered in less than 12 hours after death
should exhibit evidence that chilling began on the harvest vessel (e.g. at receipt
the internal temperature of the fish is below ambient air and water temperature);
- It is now recommended that the date and time of off-loading be recorded on
receiving records maintained by the primary processor;
- It is no longer recommended that primary (first) processors check for the
adequacy of ice, refrigerated seawater, refrigerated brine, or other cooling media
at receipt from the harvest vessel;
- It is no longer recommended that secondary processors check the internal temperature
of fish received from other processors. However, it is now recommended that the
checks for the adequacy of ice or other cooling media at receiving be verified
periodically by measuring the internal temperature of the fish to ensure that
it is at or below 40°F (4.4°C);
- It is now recommended that the accuracy of time/temperature data loggers or
recorder thermometers on vehicles delivering fish to secondary processors be checked
on all new suppliers' vehicles and at least quarterly thereafter;
- The table of approximate safe shelf-life for scombrotoxin-forming species
which was previously present is replaced with more generalized guidance because
the values contained in the table were apparently being misused as binding limits;
- The recommended critical limits for storage and processing are significantly
modified as follows:
- For fish that have not been previously frozen: the fish are not exposed to
ambient temperatures above 40°F (4.4°C) for more than 4 hours, cumulatively,
if any portion of that time is at temperatures above 70°F (21°C); or the
fish are not exposed to ambient temperatures above 40°F (4.4°C) for more
than 8 hours, cumulatively, as long as no portion of that time is at temperatures
above 70°F (21°C);
- For fish that have been previously frozen: the fish are not exposed to ambient
temperatures above 40°F (4.4°C) for more than 12 hours, cumulatively,
if any portion of that time is at temperatures above 70°F (21°C); or the
fish are not exposed to ambient temperatures above 40°F (4.4°C) for more
than 24 hours, cumulatively, as long as no portion of that time is at temperatures
above 70°F (21°C);
- There is no longer a minimum length of frozen storage in the definition of
"previously frozen product;"
- It is now recommended that ambient air temperature be monitored at the processing
and packaging critical control points;
- A new concept is introduced to assist in the assessment of whether the hazard
is significant at receiving by the primary (first) processor: the hazard may not
be significant if the worst case environmental conditions (i.e. air and water
temperatures) during the harvest season in a particular region would not permit
the formation of histamine during the time necessary to harvest and transport
the fish to the primary processor;
- The recommendations previously provided for refrigerated storage are now also
recommended for refrigerated processing;
- For purposes of selecting fish for histamine analysis and sensory examination
it is now recommended that lots be identified that contain only one species;
- It is now recommended that the number of fish tested for internal temperature
at receipt by the primary (first) processor be one per ton for lots of 10 tons
or more, and one per 1000 lbs. for lots of under 10 tons, as long as at least
12 fish per lot are examined;
- It is now recommended that no less than 18 fish per lot be analyzed for
histamine at receipt by the primary (first) processor except where the lot
is smaller than 18 fish (histamine testing control strategy only). The fish
collected for analysis may be composited for analysis if the critical limit
is reduced accordingly;
- A sample size of 60 fish and a reject level of any fish at or above 50 ppm
histamine is now recommended as one option for corrective action when the processing
critical limits have been violated;
- Another option is now provided for corrective action when the sensory critical
limit has been violated (primary processor):
- Perform histamine analysis on the lot (i.e. fish of common origin) by analyzing
60 fish (or the entire lot for lots smaller than 60 fish) and rejecting the lot
if any are found with histamine greater than or equal to 50 ppm. If found, the
lot may be subdivided and reanalyzed at the same rate, rejecting those portions
where a unit greater than or equal to 50 ppm is found. The fish collected for
analysis may be composited for analysis if the critical limit is reduced accordingly;
AND
- Perform a sensory examination of all fish in the lot;
- It is now recognized that when refrigerated fish are transported only short
distances (4 hours or less) from processor to processor, a suitable alternative
to requiring continuous monitoring during transit may be for the secondary processor
to check the internal temperature of the fish upon receipt;
- It is no longer recommended that maximum indicating thermometers be used to
monitor ambient air temperature in storage coolers;
- It is now recommended that high temperature alarms used to monitor ambient
air temperature in storage coolers be connected to a 24-hour monitoring service.
The recommendations in Chapter 11 for the control of
aquaculture drugs are changed as follows:
- Additional information is now provided about the labeling of approved conditions
of use on aquaculture drugs;
- Information is now included about the newly approved drug, chorionic gonadotropin;
- Information is now included about additional approved uses for formalin solution;
- An additional approved manufacturer of tricaine methansolfonate is now listed;
- Thiamine hydrochloride is now listed as a low regulatory priority drug for
treatment of thiamine deficiency in salmonids;
- Discontinued use of the supplier until corrections are made is now recommended
as a corrective action for all control strategy examples in which aquacultured
fish are received from the producer.
The recommendations in Chapter 12 for the control of
pathogen growth and toxin formation (other than Clostridium botulinum) as a result
of time/temperature abuse are changed as follows:
- A third set of recommended critical limits is now provided for control during
processing steps: If the product is held at internal temperatures both above and
below 70°F (21.1°C), exposure times above 50°F (10°C) should ordinarily
be limited to 4 hours, as long as no more than 2 of those hours are above 70°F
(21.1°C);
- Additional information and guidance is now provided to assist in the development
of critical limits during processing and storage, including:
- Examples of product time/temperature profiles;
- A recommendation that most microbiologically sensitive products be stored
at or below 40°F (4.4°C), except where control of nonproteolytic C.
botulinum by refrigeration is necessary, in which case storage at 38°F
(3.3°C) is usually appropriate;
- Additional verification is now recommended, as follows:
- The accuracy of recorder thermometers and other instruments used to monitor
temperature in transportation cargo areas should be checked on new suppliers'
vehicles and at least quarterly for each supplier thereafter;
- When visual checks of ice or cooling media are used to monitor the adequacy
of coolant, the internal temperatures of the fish should be periodically checked
to ensure that the ice or cooling media is sufficient to maintain product temperatures
at 40°F (4.4°C) or less;
- There is now a specific acknowledgement that frozen product storage and receipt
of frozen raw materials are not likely CCPs;
- Background information on the pathogens of concern now indicates that the
infective doses of Listeria monocytogenes and Vibrio parahaemolyticus
are unknown;
- The example HACCP plans in Tables 12-1 and 12-2 are modified to correct an
error in the Second Edition, in which the cooked crab cooler step was inadvertently
included as a CCP in the Gulf Coast blue crab processing method (Table 12-1),
rather than the East Coast blue crab processing method (Table 12-2).
- It is now recognized that when refrigerated fishery products are transported
only short distances (4 hours or less) from processor to processor, a suitable
alternative to requiring continuous monitoring during transit may be for the secondary
processor to check the internal temperature of the fish upon receipt;
- It is no longer recommended that maximum indicating thermometers be used to
monitor ambient air temperature in storage coolers;
- It is now recommended that high temperature alarms used to monitor ambient
air temperature in storage coolers be connected to a 24-hour monitoring service.
The recommendations in Chapter 13 for the control of
C. botulinum toxin formation are changed as follows:
- The introductory material is extensively reorganized and revised to provide
greater clarity;
- Information is now provided on a recommended minimum oxygen transmission rate
for oxygen-permeable packages (10,000 cc/m2/24 hrs);
- Fishery products packaged in deep containers from which the air is expressed
are now identified as presenting a C. botulinum toxin formation hazard;
- Hot smoked product in aerobic packaging is no longer identified as presenting
a C. botulinum toxin formation hazard sufficient to require preventive
controls in a HACCP plan. However, note that the Association of Food and Drug
Officials recommends a minimum water phase salt content of 2.5% in aerobically-packaged
smoked fish;
- Controls are no longer recommended specifically for the control of C. botulinum
toxin formation as a result of time/temperature abuse during the processing of
unpackaged product. Instead it is now recommended that the controls recommended
for pathogens other than C. botulinum be applied as appropriate. The chapter
also acknowledges that C. botulinum toxin formation is possible in unpackaged
or aerobically packaged product, but that, under those conditions, it requires
the type of severe temperature abuse that is not reasonably likely to occur in
most food processing environments;
- It is now recognized that when refrigerated fishery products are transported
only short distances (4 hours or less) from processor to processor, a suitable
alternative to requiring continuous monitoring during transit may be for the secondary
processor to check the internal temperature of the fish upon receipt;
- It now states that 20% salt is the level needed to ensure the safety of a
shelf stable product relative to all pathogens (based on the maximum salt level
for growth of S. aureus), rather than providing the apparently misleading
statement that 10% salt is the level needed in a shelf stable product for the
control of C. botulinum type A and proteolytic types B and F;
- It now provides instruction to consult Chapter 12 for information on refrigerated
storage temperature critical limits suitable for the control of pathogens other
than C. botulinum, rather than providing the apparently misleading statement
that 50°F (10°C) is an appropriate critical limit for the control of C.
botulinum type A and proteolytic types B and F. Refrigeration at or below
40°F (4.4°C) is recommended for the control of all pathogens;
- Specific guidance is now provided for control of C. botulinum toxin
formation in refrigerated, reduced oxygen packaged, pasteurized fishery products,
including: 1) those that receive a nonproteolytic C. botulinum pasteurization
process in the final container; and 2) those that receive a nonproteolytic C.
botulinum cook and are then hot filled into the final container;
- Specific guidance is now provided for control of C. botulinum toxin
formation in refrigerated, reduced oxygen packaged pasteurized surimi-based products,
including a recommended control of 2.5% salt in combination with a pasteurization
process in the finished product container of 185°F (85°C) (internal temperature)
for at least 15 minutes;
- The use of recorder thermometers or digital time/temperature data loggers
throughout distribution and retail storage and sales is no longer recommended
as an alternative to a second barrier to toxin formation by C. botulinum
type E and nonproteolytic types B and F;
- It is now acknowledged that, for refrigerated products that are packaged
in oxygen-permeable packaging, an oxygen-impermeable overwrap may be used
to extend shelf life while the product is under the control of the processor,
as long as the overwrap is removed before the product leaves the processor's
control;
- It is now recommended that nitrite analysis accompany water phase salt analysis,
as appropriate, when such analysis is used as the means of monitoring the brining,
dry salting and/or drying steps;
- It is now recommended that the accuracy of time/temperature data loggers or
recorder thermometers on vehicles delivering fish to secondary processors be checked
on all new suppliers' vehicles and at least quarterly thereafter;
- It is no longer recommended that maximum indicating thermometers be used to
monitor ambient air temperature in storage coolers;
- It is now recommended that high temperature alarms used to monitor ambient
air temperature in storage coolers be connected to a 24-hour monitoring service.
The recommendations in Chapter 14 for the control of
pathogen growth and toxin formation as a result of inadequate drying are changed
as follows:
- Controls are now provided for partial drying of refrigerated, reduced oxygen
packaged foods, where drying is targeted for the control of C. botulinum
type E and nonproteolytic types B and F. The controls are designed to ensure that
the water activity of the finished product is below 0.97;
- The importance of packaging in preventing rehydration of dried products is
now noted.
The recommendations in Chapter 16 for the control of
pathogen survival through cooking are changed as follows:
- The concept of exceptionally lethal cooking processes is eliminated;
- Information is now provided about the target organism and degree of destruction
for cooking processes, including recommendations that:
- The target organism should ordinarily be L. monocytogenes;
- The cook should ordinarily provide a 6D process;
- Information is now provided about cooking processes that are designed to eliminate
the spores of Clostridium botulinum type E and nonproteolytic types B and
F, such as cooking of soups and sauces that will be reduced oxygen packaged (e.g.
vacuum packaged) and distributed refrigerated. The information includes the recommendation
that such products be hot filled in a continuous filling system to minimize the
risk of recontamination between cooking and finished product packaging.
The recommendations in Chapter 17 for the control of pathogen
survival through pasteurization are changed as follows:
- Information is now provided about the target organism and degree of destruction
for pasteurization processes, including recommendations that:
- The target organism should ordinarily be Clostridium botulinum type
E and nonproteolytic types B and F if the product is reduced oxygen packaged (e.g.
vacuum packaged), does not contain other barriers that are sufficient to prevent
growth and toxin formation by this pathogen, and is stored or distributed refrigerated
(not frozen);
- The target organism should ordinarily be L. monocytogenes for other
products (e.g. frozen products);
- The pasteurization process should ordinarily provide a 6D reduction in the
numbers of the target pathogen.
The recommendations in Chapter 18 for the control of
pathogen introduction after pasteurization are changed as follows:
- Information is now provided on hot filling products such as soups and sauces
that are cooked to eliminate the spores of Clostridium botulinum type E
and nonproteolytic types B and F, and then reduced oxygen packaged (e.g. vacuum
packaged) and then distributed refrigerated (not frozen). The minimum recommended
hot fill temperature, 185°F (85°C), is designed to minimize the risk of
recontamination between cooking and finished product packaging;
- It is now recommended that cooling water flow rate be controlled when UV treatment
is used to treat container cooling water.
The recommendations in Chapter 19 for the control of
allergens, food intolerance substances and prohibited food and color additives
are changed as follows:
- Controls similar to those previously recommended for use by primary processors
are now recommended for use by secondary processors, except that reliance
on raw material labeling or documents accompanying the raw material shipment
(in the case of unlabeled product) are included as recommended control strategies
when the raw material is received from another processor;
- Undeclared sulfiting agents are now identified as a potential hazard in cooked
octopus;
- General information is now provided on the control of allergenic proteins
in foods. Controls similar to those previously recommended to ensure proper labeling
for certain food and color additives are now recommended if foods that contain
allergenic proteins are part of or are directly added to a fishery product. Additionally,
reference is made to controlling inadvertent introduction of allergenic proteins,
because of cross-contact, through a rigorous sanitation regime, either as part
of a prerequisite program or as part of HACCP itself.
The recommendations in Chapter 20 for the control of
metal inclusion are changed as follows:
- The reference to the point at which FDA's Health Hazard Evaluation Board has
supported regulatory action is corrected to indicate a metal fragment of between
0.3" [7 mm]
and 1.0" [25 mm];
- The recommended corrective actions to regain control over the operation after
metal is detected in the product now include:
- Locating and correcting the source of the metal fragments; and
- Making adjustments to the materials, equipment, and/or process, as needed,
to prevent future introduction of metal fragments;
- Injection needles and metal ties are now identified as additional sources
of metal fragments in the processing environment;
- It is now recognized that visually inspecting equipment for damage or missing
parts may only be feasible with relatively simple equipment, such as band saws,
small orbital blenders, and wire-mesh belts.
Chapter 21 has been added to provide guidance on the
control of glass inclusion as a result of the use of glass containers.
The recommendations in the Appendices are changed as follows:
- The maximum water phase salt level for growth of Bacillus cereus is
now given as 10 percent;
- The maximum water phase salt level for growth of Staphylococcus aureus
is now given as 20 percent;
- The minimum temperature for growth of pathogenic strains of Escherichia
coli is now given as 43.7°F (6.5°C);
- The maximum temperature for growth of Vibrio parahaemolyticus is now
given as 113.5°F (45.3°C);
