[Code of Federal Regulations] [Title 9, Volume 2] [Revised as of January 1, 2008] From the U.S. Government Printing Office via GPO Access [CITE: 9CFR430.4] [Page 665-667] TITLE 9--ANIMALS AND ANIMAL PRODUCTS CHAPTER III--FOOD SAFETY AND INSPECTION SERVICE, DEPARTMENT OF AGRICULTURE PART 430_REQUIREMENTS FOR SPECIFIC CLASSES OF PRODUCT-- Table of Contents Sec. 430.4 Control of Listeria monocytogenes in post-lethality exposed ready-to-eat products. (a) Listeria monocytogenes can contaminate RTE products that are exposed to the environment after they have undergone a lethality treatment. L. monocytogenes is a hazard that an establishment producing post-lethality exposed RTE products must control through its HACCP plan or prevent in the processing environment through a Sanitation SOP or other prerequisite program. RTE product is adulterated if it contains L. monocytogenes or if it comes into direct contact with a food contact surface which is contaminated with L. monocytogenes. (b) In order to maintain the sanitary conditions necessary to meet this requirement, an establishment producing post-lethality exposed RTE product must comply with the requirements included in one of the three following alternatives: (1) Alternative 1. Use of a post-lethality treatment (which may be an antimicrobial agent) that reduces or eliminates microorganisms on the product and an antimicrobial agent or process that suppresses or limits the growth of L. monocytogenes. If an establishment chooses this alternative: (i) The post-lethality treatment must be included in the establishment's HACCP plan. The antimicrobial agent or process used to suppress or limit the growth of the pathogen must be included in either the establishment's HACCP plan or its Sanitation SOP or other prerequisite program. (ii) The establishment must validate the effectiveness of the post- lethality treatment incorporated in its HACCP plan in accordance with Sec. 417.4. The establishment must document, either in its HACCP plan or in its Sanitation SOP or other prerequisite program, that the antimicrobial agent or process, as used, is effective in suppressing or limiting growth of L. monocytogenes. (2) Alternative 2. Use of either a post-lethality treatment (which may be an antimicrobial agent) that reduces or eliminates microorganisms on the product or an antimicrobial agent or process that suppresses or limits growth of L. monocytogenes. If an establishment chooses this alternative: (i) The post-lethality treatment must be included in the establishment's HACCP plan. The antimicrobial agent or process used to suppress or limit growth of the pathogen must be included in either the establishment's HACCP plan or its Sanitation SOP or other prerequisite program. (ii) The establishment must validate the effectiveness of a post- lethality treatment incorporated in its HACCP plan in accordance with Sec. 417.4. The establishment must document in its HACCP plan or in its Sanitation SOP or other prerequisite program that the antimicrobial agent or process, as used, is effective in suppressing or limiting growth of L. monocytogenes. (iii) If an establishment chooses this alternative and chooses to use only an antimicrobial agent or process that suppresses or limits the growth of L. monocytogenes, its sanitation program must: (A) Provide for testing of food contact surfaces in the post- lethality processing environment to ensure that the surfaces are sanitary and free of L. monocytogenes or of an indicator organism; (B) Identify the conditions under which the establishment will implement hold-and-test procedures following a positive test of a food- contact surface for L. monocytogenes or an indicator organism; (C) State the frequency with which testing will be done; (D) Identify the size and location of the sites that will be sampled; and (E) Include an explanation of why the testing frequency is sufficient to ensure that effective control of L. monocytogenes or of indicator organisms is maintained. [[Page 666]] (iv) An establishment that chooses this alternative and uses a post- lethality treatment of product will likely be subject to more frequent verification testing by FSIS than if it had chosen Alternative 1. An establishment that chooses this alternative and uses an antimicrobial agent or process that suppresses or limits the growth of L. monocytogenes will likely be subject to more frequent FSIS verification testing than if it uses a post-lethality treatment. (3) Alternative 3. Use of sanitation measures only. (i) If an establishment chooses this alternative, its sanitation program must: (A) Provide for testing of food contact surfaces in the post- lethality processing environment to ensure that the surfaces are sanitary and free of L. monocytogenes or of an indicator organism; (B) Identify the conditions under which the establishment will implement hold-and-test procedures following a positive test of a food- contact surface for L. monocytogenes or an indicator organism; (C) State the frequency with which testing will be done; (D) Identify the size and location of the sites that will be sampled; and (E) Include an explanation of why the testing frequency is sufficient to ensure that effective control of L. monocytogenes or of indicator organisms is maintained. (ii) An establishment producing a deli product or a hotdog product, in addition to meeting the requirements of paragraph (b)(3)(i) of this section, must meet the following requirements: (A) The establishment must verify that the corrective actions that it takes with respect to sanitation after an initial positive test for L. monocytogenes or an indicator organism on a food contact surface in the post-lethality processing environment are effective by conducting follow-up testing that includes a targeted test of the specific site on the food contact surface area that is the most likely source of contamination by the organism and such additional tests in the surrounding food contact surface area as are necessary to ensure the effectiveness of the corrective actions. (B) During this follow-up testing, if the establishment obtains a second positive test for L. monocytogenes or an indicator organism, the establishment must hold lots of product that may have become contaminated by contact with the food contact surface until the establishment corrects the problem indicated by the test result. (C) Further, in order to be able to release into commerce the lots of product that may have become contaminated with L. monocytogenes, the establishment must sample and test the lots for L. monocytogenes or an indicator organism using a sampling method and frequency that will provide a level of statistical confidence that ensures that each lot is not adulterated with L. monocytogenes. The establishment must document the results of this testing. Alternatively, the establishment may rework the held product using a process that is destructive of L. monocytogenes or the indicator organism. (iii) An establishment that chooses Alternative 3 is likely to be subject to more frequent verification testing by FSIS than an establishment that has chosen Alternative 1 or 2. An establishment that chooses Alternative 3 and that produces deli meat or hotdog products is likely to be subject to more frequent verification testing than one that does not produce such products. (c) For all three alternatives in paragraph (b): (1) Establishments may use verification testing that includes tests for L. monocytogenes or an indicator organism, such as Listeria species, to verify the effectiveness of their sanitation procedures in the post- lethality processing environment. (2) Sanitation measures for controlling L. monocytogenes and procedures for antimicrobial agents or processes that suppress or limit the growth of the pathogen may be incorporated either in the establishment's HACCP plan or in its Sanitation SOP or other prerequisite program. When these control procedures are incorporated into the Sanitation SOP or prerequisite program, and not as a CCP in the HACCP [[Page 667]] plan, the establishment must have documentation that supports the decision in its hazard analysis that L. monocytogenes is not a hazard that is reasonably likely to occur. (3) The establishment must maintain sanitation in the post-lethality processing environment in accordance with part 416. (4) If L. monocytogenes control measures are included in the HACCP plan, the establishment must validate and verify the effectiveness of measures for controlling L. monocytogenes included in its HACCP plan in accordance with Sec. 417.4. (5) If L. monocytogenes control measures are included in the Sanitation SOP, the effectiveness of the measures must be evaluated in accordance with Sec. 416.14. (6) If the measures for addressing L. monocytogenes are addressed in a prerequisite program other than the Sanitation SOP, the establishment must include the program and the results produced by the program in the documentation that the establishment is required to maintain under 9 CFR 417.5. (7) The establishment must make the verification results that demonstrate the effectiveness of the measures it employs, whether under its HACCP plan or its Sanitation SOP or other prerequisite program, available upon request to FSIS inspection personnel. (d) An establishment that produces post-lethality exposed RTE product shall provide FSIS, at least annually, or more often, as determined by the Administrator, with estimates of annual production volume and related information for the types of meat and poultry products processed under each of the alternatives in paragraph (b) of this section. (e) An establishment that controls L. monocytogenes by using a post- lethality treatment or an antimicrobial agent or process that eliminates or reduces, or suppresses or limits the growth of the organism may declare this fact on the product label provided that the establishment has validated the claim.
