Peanut Butter Safety Guide for Boston Residents & Restaurants

FDA & Massachusetts Peanut Butter Regulations

Peanut butter manufacturers must comply with FDA Food Safety Modernization Act (FSMA) requirements, which include preventive controls, supplier verification, and recall procedures. Massachusetts Department of Public Health enforces additional state-level food safety standards and conducts facility inspections. Restaurants and food service operations in Boston must maintain proper storage temperatures (below 70°F for unopened jars), separate peanut products to prevent cross-contamination, and clearly label items containing peanuts due to allergen regulations. The FDA's Peanut Butter Guidance Document (updated 2020) outlines requirements for pathogen testing and Aflatoxin monitoring, which applies to all products sold in Massachusetts.

Common Peanut Butter Contamination Risks

Salmonella and Listeria monocytogenes are the primary pathogens associated with peanut butter recalls. Aflatoxin—a naturally occurring mold toxin produced by Aspergillus fungi—is monitored during crop harvesting and processing; the FDA sets a maximum limit of 20 ppb in finished peanut butter products. Cross-contamination occurs when peanut products contact allergens or come into contact with contaminated surfaces in Boston food establishments. Opened jars stored improperly or past expiration dates increase bacterial growth risk. Consumers with peanut allergies face severe reactions even from trace amounts, making transparent labeling and dedicated prep areas critical for restaurants.
