Heterocyclic amines (HCAs) and polycyclic aromatic hydrocarbons (PAHs) are chemicals formed when muscle meat, including beef, pork, fish, or poultry, is cooked using high-temperature methods, such as pan frying or grilling directly over an open flame (1). In laboratory experiments, HCAs and PAHs have been found to be mutagenicโ€”that is, they cause changes in DNA that may increase the risk of cancer
