This bill adds alpha-gal, a sugar molecule found in certain animal products and red algae, to the federal definition of "major food allergens" that must be labeled on packaged foods. Alpha-gal is a protein compound that triggers allergic reactions in people with alpha-gal syndrome, a condition that develops after tick bites and causes reactions to red meat and certain other animal products. The legislation would require food manufacturers to clearly disclose alpha-gal on ingredient labels, similar to how they currently label common allergens like peanuts and shellfish. The new requirement would take effect 18 months after the bill becomes law, giving manufacturers time to update their labeling practices. This change would help people with alpha-gal allergies identify and avoid foods that could trigger dangerous reactions.
