    (c) Labeling. (1) The label and labeling of retail packages of foods 
irradiated in conformance with paragraph (b) of this section shall bear 
the following logo along with either the statement
[GRAPHIC] [TIFF OMITTED] TR01FE93.000


[[Page 435]]


    ``Treated with radiation'' or the statement ``Treated by 
irradiation'' in addition to information required by other regulations. 
The logo shall be placed prominently and conspicuously in conjunction 
with the required statement. The radiation disclosure statement is not 
required to be more prominent than the declaration of ingredients 
required under Sec. 101.4 of this chapter. As used in this provision, 
the term ``radiation disclosure statement'' means the written statement 
that discloses that a food has been intentionally subject to 
irradiation.
    (2) For irradiated foods not in package form, the required logo and 
phrase ``Treated with radiation'' or ``Treated by irradiation'' shall be 
displayed to the purchaser with either (i) the labeling of the bulk 
container plainly in view or (ii) a counter sign, card, or other 
appropriate device bearing the information that the product has been 
treated with radiation. As an alternative, each item of food may be 
individually labeled. In either case, the information must be 
prominently and conspicuously displayed to purchasers. The labeling 
requirement applies only to a food that has been irradiated, not to a 
food that merely contains an irradiated ingredient but that has not 
itself been irradiated.
    (3) For a food, any portion of which is irradiated in conformance 
with paragraph (b) of this section, the label and labeling and invoices 
or bills of lading shall bear either the statement ``Treated with 
radiation--do not irradiate again'' or the statement ``Treated by 
irradiation--do not irradiate again'' when shipped to a food 
manufacturer or processor for further processing, labeling, or packing.
