California's New Law Forces Chains to Reveal Hidden Food Allergens

A new law in California will soon change how larger restaurant chains share allergen information. Starting July 1, customers at big-name eateries will see clearer details about major food allergens in menu items. The rule aims to help diners with allergies make safer choices when eating out. The requirement comes from Senate Bill 68, also called the Allergen Disclosure for Dining Experiences Act. It applies to chains with 20 or more locations under the same name and offering similar menus. Restaurants must now list allergens either directly on menus, through digital platforms with a written backup, or by using standard pictograms.

The law covers nine major allergens: milk, eggs, fish, crustacean shellfish, tree nuts, wheat, peanuts, soybeans, and sesame. However, it does not demand 'may contain' warnings or force kitchens to prevent cross-contact. Small mobile food vendors, temporary setups, and prepackaged foods (already regulated by federal rules) are also exempt. Bay Area residents will spot these changes in chain restaurants, fast-casual spots, and even drive-thru menus. The updates will also appear on apps, online ordering pages, and QR-code menus. With nearly 7% of U.S. adults and 5% of children diagnosed with food allergies in 2024, the law provides essential information for many families.

The new rule takes effect on July 1, giving diners more transparency about allergens in their meals. While it does not eliminate cross-contact risks, it ensures that key allergen details are easily accessible. Larger chains must now comply, making eating out safer for those with food allergies.
