Food Safety:
It's in Your Hands! |
"Wash your hands."
Do you remember hearing your mother tell you this when you
were young? It is still good advice. We know that our hands can
carry harmful bacteria. Think about all the things you touch throughout
the day:
- Food, including raw meat
- Tables, desks, and other countertops
- Pets
- Cars
- Children
- Dirty diapers
- Runny noses
- Cigarettes
- Toilet seats and handles
- Doorknobs
Because bacteria are everywhere they are on our bodies, too.
We spread bacteria by constantly touching our hair, nose, and
face. It is, therefore, important to wash our hands frequently.
When Is It Important To Wash Your Hands?
Wash Your Hands After
- Using the bathroom
- Handling raw foods such as meats, poultry, fruits, and vegetables
- Changing a baby's diaper
- Sneezing and coughing
Using the Bathroom
Washing your hands after using the bathroom seems simple enough,
but few people realize how important it is. Many types of bacteria
live in the feces of animals and humans. This includes some of
the most deadly bacteria such as E. coli 0157:H7. Some people
can even carry the organism without becoming ill themselves, but
when they pass the organism to someone else that person can become
quite ill. The best way to remove these bacteria is by washing
your hands.
Handling Raw Foods
You probably realize the need to wash your hands after handling
raw meats and poultry, but what about after handling raw fruits
and vegetables? In addition to pesticides, microorganisms can
be found on the surface of fresh produce. Bacteria are everywhere--in
the air and in the soil; it is easy for these bacteria to get
on fruits and vegetables. One major way bacteria get on fruits
and vegetables is from animals in the fields. Deer, rabbits, even
rats and mice come to eat the food and leave behind their feces.
These feces are deposited in the soil. When it rains, they are
splashed onto the produce. When you handle the raw foods, your
hands can become contaminated.
Changing a Baby's Diaper
As sweet as babies are, they still can have bacteria in their
feces. Always wash your hands after changing a diaper. It is also
a good practice to wipe off your hands with a damp paper towel
after discarding the dirty diaper and before you put on the clean
one. This will help prevent cross contamination of the bacteria
in the baby's diaper.
Sneezing and Coughing
Have you ever thought about why your nose runs? Sometimes it
is caused by an allergic reaction and bacteria are not involved.
When you have a cold, it is caused by an infection. Colds are
the result of a viral infection. Whenever you wipe your nose with
your hands, you can spread the virus to whatever you touch.
Wash Your Hands Before
- Eating or drinking
- Handling a baby
- Preparing food
Eating or Drinking
As already mentioned, bacteria are everywhere. The skin has
many types of bacteria living on it that we cannot see. They are
so small that millions can be on our hands without our knowing
it and can easily be passed to the food we prepare.
Handling a Baby
Because babies are so little they are the most susceptible
to bacterial infections. For this reason you should wash your
hands before handling a baby. It is especially important to wash
your hands before you handle any food for babies, especially their
bottles.
Preparing Food
We always think about washing our hands after handling food,
but what about before? Some foods, such as canned foods, are free
from bacteria before you eat them. Touching them with dirty hands
can cause contamination.
Where Should You Wash Your Hands?
You should wash your hands in a hand-washing sink where food
is not being prepared. Never use the kitchen sink to wash your
hands after you have been doing something in another area of the
house and enter the kitchen to start cooking. Of course, after
you have washed your hands and started the cooking process, you
will rinse and wash your hands many times throughout the cooking
of a meal. The kitchen sink can become contaminated if you wash
your hands there after using the bathroom. The bacteria can then
be introduced to foods such as lettuce and tomatoes that may be
placed in the sink. Make it a household practice to wash your
hands in the bathroom sink before starting the cooking process.
During food preparation, your hands can become soiled and wet.
Always wash them when they become soiled and especially after
handling raw meat or poultry. Dry your hands with a towel for
hand drying only. Do not use the same towel that you would use
to dry clean dishes or to dry the counter. A damp, hand-drying
towel may contain bacteria that can grow to millions after several
hours.
