Nut Milk Safety Guide for San Francisco
Nut milks—including almond, cashew, and oat alternatives—have become staples in San Francisco restaurants and households. However, improper handling, cross-contamination, and manufacturing defects can introduce pathogens like Salmonella and Listeria monocytogenes into these products. Understanding local regulations and staying informed about recalls is essential for food safety.
San Francisco Health Code Requirements for Nut Milk Storage & Handling
The San Francisco Department of Public Health enforces California Food Code Title 13, which requires all ready-to-drink beverages—including nut milks—to be stored at 41°F or below if refrigerated. Restaurants and retailers must maintain temperature logs and segregate nut milk products from allergen-prone items to prevent cross-contamination. Once opened, nut milk should be discarded after 7 days per SF health standards. Commercial establishments must also verify supplier certifications and maintain traceability documentation, enabling rapid response if the FDA or CDC issues a recall notice.
Common Nut Milk Contamination Risks & Recall Patterns
Nut milks are vulnerable to contamination during manufacturing, particularly in facilities processing tree nuts or seeds. Salmonella contamination has been identified in almond and cashew milk products, while Listeria monocytogenes poses a risk in improperly pasteurized batches. Cross-contact with peanuts or other allergens remains a critical concern in production environments. The FDA monitors nut milk manufacturing through the FSMA preventive controls rule, and San Francisco retailers must verify that suppliers comply with these standards. Recent years have seen multiple recalls affecting distributed products in California, making supplier verification and real-time alert monitoring essential.
