The "Strengthening Local Processing Act of 2025" seeks to bolster small and very small meat and poultry processing establishments by providing critical resources and financial support. It amends the Poultry Products Inspection Act and the Federal Meat Inspection Act to require the Secretary of Agriculture to develop and disseminate essential guidance. Specifically, within 18 months, the Secretary must establish a free, searchable database of approved peer-reviewed validation studies and publish online scale-appropriate model Hazard Analysis and Critical Control Points (HACCP) plans for various types of smaller establishments. Furthermore, within two years, comprehensive guidance on HACCP plan approval requirements will be published, all while ensuring the confidentiality of business information. The bill also aims to enhance state inspection programs and facilitate interstate commerce for these smaller processors. It increases the maximum federal share for state meat and poultry inspection expenses from 50 percent to 65 percent. For the Cooperative Interstate Shipment (CIS) program, the employee cap for eligible establishments is raised from 25 to 50, and the federal share for program costs increases from 60 percent to 80 percent. To encourage broader participation, the Secretary is mandated to conduct outreach and negotiation with at least 25 percent of eligible states annually from fiscal years 2025 through 2030, reporting on these efforts to Congress. Crucially, the legislation establishes two new grant programs to foster resilience and workforce development. The Processing Resilience Grant Program will award competitive grants, up to $500,000, to eligible entities including small processors, state-inspected facilities, and those starting new operations. These grants aim to increase processing capacity, support employee health and safety, and enhance overall sector resilience, with priority given to proposals increasing farmer access to slaughter options. Additionally, the Processor Career Training Programs will provide competitive grants to educational institutions and training centers to establish or expand career training, including structured apprenticeships, for meat and poultry processing, particularly benefiting smaller establishments. Both grant programs include simplified application processes for smaller awards and are authorized with significant appropriations through fiscal year 2030.
