Bratwurst

Bratwurst is a processed meat, and processing — grinding, mixing, and seasoning — gives histamine-producing bacteria more surface area and time to work.

• Processing raises histamine — once meat is ground and mixed, histamine can build up faster than in a whole, fresh cut

• Spices add another layer — many traditional bratwurst seasonings include spices like paprika that appear on some histamine intolerance lists, though the evidence for individual spices is not consistent and personal tolerance varies

Freshly made bratwurst from a trusted butcher may behave differently than packaged or pre-made versions.
