TMAO MEDIUM (TRIMETHYLAMINE-N-OXIDE MEDIUM) (as per APHA)

Campylobacters are mainly present in the intestinal tract of animals and therefore contaminate the foods of animal origin. Campylobacter lari is a thermophilic species that was first isolated from gulls and has since been isolated from other avian species, dogs, cats and chickens. C. lari has been frequently reported from humans with bacteremia and with gastrointestinal and urinary tract infections. TMAO is an osmolyte found in salt water fish, sharks and rays, molluscs and crustaceans. TMAO decomposes to trimethylamine (TMA) which is the main odorant that is characteristic of degrading seafood.
