     CHAPTER III--FOOD SAFETY AND INSPECTION SERVICE, DEPARTMENT OF 
                               AGRICULTURE
 
PART 424--PREPARATION AND PROCESSING OPERATIONS--Table of Contents
 
          Subpart C--Food Ingredients and Sources of Radiation
 
Sec. 424.22  Certain other permitted uses.

    (a) Under appropriate declaration as required in parts 316 and 317 
of this chapter, the following substances may be added to meat:
    (1) General. Common salt, approved sugars (sucrose, cane or beet 
sugar), maple sugar, dextrose, invert sugar, honey, corn syrup solids 
(corn syrup, glucose syrup and fructose), wood smoke, vinegar, 
flavorings, spices, sodium nitrate, sodium nitrite, potassium nitrate, 
potassium nitrite, and other food and color additives specified in the 
chart in paragraph (c) of this section may be added to meat under 
conditions, if any, specified in this part or in part 317 of this 
chapter.
    (2) Artifical flavorings. Other harmless artificial flavorings may 
be added to meat, with the approval of the Administrator in specific 
cases.
    (3) Coloring matter and dyes. Coloring matter and dyes, other than 
those specified in a regulation permitting that use in this chapter or 
in 21 CFR Chapter I, Subchapter A and Subchapter B, may be applied to 
meat mixed with rendered fat, applied to natural and artificial casings, 
and applied to such casings enclosing products, if approved by the 
Administrator in specific cases. When any coloring matter or dye is 
applied to casings, there shall be no penetration of coloring into the 
product.
    (b) Use of nitrite and sodium ascorbate or sodium erythorbate 
(isoascorbate) in bacon.
    (1) Pumped bacon. With respect to bacon injected with curing 
ingredients and massaged bacon, sodium nitrite shall be used at 120 
parts per million (ppm) ingoing or an equivalent amount of potassium 
nitrite shall be used (148 ppm ingoing); and 550 ppm of sodium ascorbate 
or sodium erythorbate (isoascorbate) shall be used. Sodium ascorbate or 
sodium erythorbate have a molecular weight of approximately 198. 
Hydrated forms of these substances shall be adjusted to attain the 
equivalent of 550 ppm of sodium ascorbate or sodium erythorbate.
    (i) The Department shall collect samples of pumped bacon from 
producing plants and analyze them for the level of nitrosamines by the 
Thermal Energy Analyzer (TEA). In the event that a TEA analysis 
indicates that a confirmable level of nitrosamines might be present, 
additional samples shall be collected and analyzed by gas 
chromatography. Presumptive positive results

[[Page 648]]

must be confirmed by mass spectrometry before being considered positive. 
If during the interval required for the Department to analyze the 
confirmatory samples by gas chromatography and mass spectrometry, 
changes are made in processing procedures which are expected to result 
in no confirmable levels of nitrosamines in pumped bacon produced by 
these new procedures, an establishment may submit samples to USDA for 
analysis upon prior notification and arrangements with USDA. If, 
however, an establishment furnishes USDA with laboratory results from 
testing five consecutive lots of pumped bacon produced under the new 
procedures and the testing is performed by the USDA methodology and 
procedures, those results will be utilized in making the determination 
concerning the product produced under the new procedures. Should the 
results of these tests reveal that confirmable levels of nitrosamines 
are not indicated in any of the five consecutive lots, the confirmation 
analysis by USDA shall be terminated and the establishment shall revert 
to normal monitoring status. In the event the test results continue to 
indicate nitrosamines, however, USDA shall proceed in its confirmation 
analysis on the original samples taken for confirmation. If any one of 
the original samples collected by USDA for confirmation is found to 
contain confirmable levels of nitrosamines, all pumped bacon in the 
producing establishment and all future production will be retained. The 
Department shall sample and analyze such retained pumped bacon for 
nitrosamines on a lot by lot basis. A production lot shall be that 
pumped bacon produced by the establishment in any single shift. Samples 
from any lot of pumped bacon under retention found to contain 
nitrosamines at a confirmable level shall cause the lot of pumped bacon 
to be disposed of in a manner to ensure it will not form nitrosamines 
when cooked. Such disposal may include incorporation of the uncooked 
pumped bacon as an ingredient of another meat provided it is processed 
for eating without further preparation in a manner to preclude the 
formation of nitrosamines. Bacon subsequently produced shall not be 
retained because of nitrosamines if the operator of the establishment 
makes adjustments in the processing of the product and laboratory 
results obtained by TEA analysis of samples from five consecutive normal 
sized lots of pumped bacon indicates that the product being produced 
contains no confirmable levels of nitrosamines. These tests from five 
consecutive normal sized lots of pumped bacon shall be conducted by the 
Department. However, if the establishment furnishes the Department with 
the results of tests conducted under the methodology and procedures used 
by the Department, such test results will be utilized in making the 
determination concerning the nitrosamine content of the product. All 
tests of pumped bacon for nitrosamines under this paragraph (b)(1)(i) 
shall be made on pumped bacon cooked at 340 degrees F. for 3 minutes on 
each side. In order to determine that no confirmable levels of 
nitrosamines are present in a sample tested, the testing must be 
performed by methodology and procedures that would detect the presence 
of any nitrosamines at 10 ppb.
    (ii) Notwithstanding the provisions of paragraph (b)(1)(i) of this 
section, sodium nitrite may be used at:
    (A) 100 ppm ingoing (potassium nitrite at 123 ppm ingoing); and 550 
ppm sodium ascorbate or sodium erythorbate (isoascorbate) shall be used; 
or
    (B) A predetermined level between 40 and 80 ppm (potassium nitrite 
at a level between 49 and 99 ppm); 550 ppm sodium ascorbate or sodium 
erythorbate (isoascorbate); and additional sucrose or other similar 
fermentable carbohydrate at a minimum of 0.7 percent and an inoculum of 
lactic acid producing bacteria such as Pediococcus acetolactii or other 
bacteria demonstrated to be equally effective in preventing the 
production of botulinum toxin at a level sufficient for the purpose of 
preventing the production of botulinum toxin.
    (C) The Department shall collect samples of bacon from 
establishments producing under paragraph (b)(1)(ii) of this section and 
analyze them for the level of nitrosamines. Samples shall be randomly 
selected throughout the production of a lot. The actual sampling

[[Page 649]]

plans and methods of analysis that are used will result in approximately 
the same likelihood as under paragraph (b)(1)(i) of this section of 
having a presumptive positive result when the true mean level of 
nitrosamines in a production lot is 10 ppb. In the event of a 
presumptive positive result, the establishment shall become subject to 
the provisions of paragraph (b)(1)(i) of this section.
    (2) Immersion cured bacon. Immersion cured bacon may be placed in a 
brine solution containing salt, nitrite and flavoring material or in a 
container with salt, nitrite and flavoring material. Sodium nitrite 
shall not exceed 120 ppm ingoing or an equivalent amount of potassium 
nitrite (148 ppm ingoing) based on the actual or estimated skin-free 
green weight of the bacon bellies.
    (3) Bacon made with dry curing materials. With respect to bacon made 
with dry curing materials, the product shall be cured by applying a 
premeasured amount of cure mixture to the bacon belly surfaces, 
completely covering the surfaces. Sodium nitrite shall not exceed 200 
ppm ingoing or an equivalent amount of potassium nitrite (246 ppm 
ingoing) in dry cured bacon based on the actual or estimated skin-free 
green weight of the bacon belly.
    (c) Irradiation of meat food and poultry products.
    (1) General requirements. Meat food and poultry products may be 
treated to reduce foodborne pathogens and to extend product shelf-life 
by the use of sources of ionizing radiation as identified in 21 CFR 
179.26(a). Official establishments must irradiate meat food and poultry 
products in accordance with 21 CFR 179.26(b), the Hazard Analysis and 
Critical Control Point (HACCP) system requirements in part 417 of this 
chapter, and the provisions of this section.
    (2) Dosimetry. Official establishments that irradiate meat food and 
poultry products must have the following procedures in place:
    (i) Laboratory operation procedures for determining the absorbed 
dose value from the dosimeter.
    (ii) Calibration criteria for verifying the accuracy and consistency 
of any means of measurement (e.g., time clocks and weight scales).
    (iii) Calibration and accountability criteria for verifying the 
traceability and accuracy of dosimeters for the intended purpose, and 
the verification of calibration at least every 12 months. To confirm 
traceability, establishments must relate, through documentation, the end 
point measurement of a dosimeter to recognized standards.
    (iv) Procedures for ensuring that the product unit is dose mapped to 
identify the regions of minimum and maximum absorbed dose and such 
regions are consistent from one product unit to another of like product.
    (v) Procedures for accounting for the total absorbed dose received 
by the product unit (e.g., partial applications of the absorbed dose 
within one production lot).
    (vi) Procedures for verifying routine dosimetry, i.e., assuring each 
production lot receives the total absorbed dose. Establishments may 
either position one dosimeter at the regions of minimum and maximum 
absorbed dose (or at one region verified to represent such) on at least 
the first, middle, and last product unit in each production lot or use 
statistically based validation and dose mapping to determine the number 
and placement of dosimeters in each production lot.
    (vii) Procedures for verifying the relationship of absorbed dose as 
measured by the dosimeter to time exposure of the product unit to the 
radiation source.
    (viii) Procedures for verifying the integrity of the radiation 
source and processing procedure. Aside from expected and verified 
radiation source activity decay for radionuclide sources, the radiation 
source or processing procedure must not be altered, modified, 
replenished, or adjusted without repeating dose mapping of product units 
to redefine the regions of minimum and maximum absorbed dose.
    (3) Documentation. Official establishments that irradiate meat food 
or poultry products must have the following documentation on premises, 
available to FSIS:
    (i) Documentation that the irradiation facility is licensed or 
possesses gamma radiation sources registered

[[Page 650]]

with the Nuclear Regulatory Commission (NRC) or the appropriate State 
government acting under authority granted by the NRC.
    (ii) Documentation that the machine radiation source irradiation 
facility is registered with the appropriate State government, if 
applicable.
    (iii) Documentation that a worker safety program addressing OSHA 
regulations (29 CFR chapter XVII) is in place.
    (iv) Citations or other documents that relate to incidences in which 
the establishment was found not to comply with Federal or State agency 
requirements for irradiation facilities.
    (v) A certification by the operator that the irradiation facility 
personnel will only operate under supervision of a person who has 
successfully completed a course of instruction for operators of food 
irradiation facilities.
    (vi) A certification by the operator that the key irradiation 
personnel, who monitor or control daily operations, have been trained in 
food technology, irradiation processing, and radiation health and 
safety.
    (vii) Guarantees from the suppliers of all food-contact packaging 
materials that may be subject to irradiation that those materials comply 
with the Federal Food, Drug, and Cosmetic Act (21 U.S.C. 301 et seq.).
    (4) Labeling. (i) The labels on packages of meat food and poultry 
products irradiated in their entirety, in conformance with this section 
and with 21 CFR 179.26(a) and (b), must bear the logo shown at the end 
of this paragraph (c)(4)(i). Unless the word ``Irradiated'' is part of 
the product name, labels also must bear a statement such as ``Treated 
with radiation'' or ``Treated by irradiation.'' The logo must be placed 
in conjunction with the required statement, if the statement is used. 
The statement is not required to be more prominent than the declaration 
of ingredients required under Sec. 317.2(c)(2). Any label bearing the 
logo or any wording of explanation with respect to this logo must be 
approved as required by Section 317.4. of this chapter or subparts M and 
N of part 381.

    (ii) For meat food or poultry products that have been irradiated in 
their entirety, but that are not sold in packages, the required logo 
must be displayed to the purchaser with either the labeling of the bulk 
container plainly in view or a counter sign, card, or other appropriate 
device bearing the information that the product has been treated with 
radiation. In either case, the information must be prominently and 
conspicuously displayed to purchasers. Unless the word ``Irradiated'' is 
part of the product name, the labeling counter sign, card, or other 
device also must bear a statement such as ``Treated with radiation'' or 
``Treated by irradiation.'' The logo must be placed in conjunction with 
the required statement, if the statement is used.
    (iii) The inclusion of an irradiated meat food or poultry product 
ingredient in any multi-ingredient meat food or poultry product must be 
reflected in the ingredient statement on the finished product labeling.
    (iv) Optional labeling statements about the purpose for radiation 
processing may be included on the product label in addition to the 
stated requirements elsewhere in this section, provided that such 
statements are not false or misleading. Statements that there has been a 
specific reduction inmicrobial pathogens must be substantiated by 
processing documentation.
