Histamine-Melamines and Dyes Sudans
Contaminants are substances that have not been intentionally added to food. Various substances can enter food at all stages of the food chain, from primary production to distribution, including processing, handling and storage. Contaminants can also come from the environment. (Codex Alimentarius)
These contaminants can be intentional and therefore cause adulteration, such as maternal milk adulterated by the fraudulent incorporation of melamine.
In addition, contamination may be due to an intrinsic denaturation of the product, the case of histamine in fish.
However, the presence of these substances in foods must be strictly controlled in order to avoid any contamination affecting their quality or rendering them harmful. (Codex Alimentarius)
