Waiver Participants Tables 

Table 1 identifies establishments currently participating in the Salmonella Initiative Program (SIP), a regulatory 

waiver program. FSIS regulations (specifically 9 CFR 303.1(h), 381.3(b), and 590.10) authorize the Administrator to 

waive for limited periods any provisions of the regulations to permit experimentation so that new procedures, 

equipment, and processing techniques may be tested to facilitate definite improvements. As described in the July 

13, 2011, Federal Register notice, Salmonella Verification Sampling Program: Response to Comments on New Agency 

Policies and Clarification of Timeline for the Salmonella Initiative Program (SIP), “[the] Salmonella Initiative Program 

(SIP) [is] for meat and poultry slaughter establishments that agree to share internal food safety data with FSIS in 

order to receive waivers of regulatory requirements. SIP benefits public health in that it encourages slaughter 

establishments to test for microbial pathogens and to respond to the ongoing results by taking steps when necessary 

to regain process control and thus to minimize the presence of pathogens of public health concern.”

Table 1 lists the waivers from regulatory requirements that FSIS has granted to SIP establishments. Establishments 

participating in SIP test for Salmonella, Campylobacter (if applicable), and generic E. coli or other indicator 

organisms and share all sample results with FSIS. The SIP data may inform future rulemaking activities. Table 1 

includes the dates establishments initially joined the SIP and the date the most recent updated waiver letter was 

issued, if applicable. Additionally, the former swine HIMP establishments have been removed from the HIMP 

column in Table 1 and have been listed in Table 3 below. 

Table 2 lists the waivers from regulatory requirements that FSIS has granted to establishments that are not part of SIP 

(for example, processing establishments). The data collected from these types of waivers are intended to inform 

future rulemaking activities.

FSIS will update this information should it grant new waivers.
