Peanut Butter Safety Guide for Louisville, KY

Louisville Health Department Regulations for Peanut Butter

The Louisville Metro Department of Public Health & Wellness enforces food code standards based on the FDA Food Safety Modernization Act (FSMA) and Kentucky state regulations. Commercial food handlers must maintain peanut butter and peanut-containing products at proper temperatures (typically 41°F or below for refrigerated items) and clearly label all allergen information. Restaurants must have documented cleaning and sanitization procedures for surfaces and equipment that contact peanut products, and staff must receive allergen training. Retail establishments must also comply with shelf-life requirements and proper rotation (FIFO: First In, First Out) to prevent expired products from reaching consumers.

Common Peanut Butter Contamination Risks

Salmonella and Listeria monocytogenes are the primary pathogens associated with peanut butter recalls, often introduced during harvesting, processing, or storage. Cross-contamination occurs when peanut butter comes into contact with raw proteins, unwashed vegetables, or contaminated utensils in restaurant kitchens and home environments. Aflatoxins—naturally occurring toxins produced by mold—can develop when peanuts are stored in warm, humid conditions (above 70°F and 70% humidity), a risk amplified in Louisville's summer months. Improper thawing of frozen peanut products and inadequate cooking temperatures in dishes containing peanut butter paste also create pathogenic survival conditions.
