Microbiological Contaminants

Overview

Microbiological organisms are present almost everywhere but are usually dormant or harmless to humans. If conditions are right, however, a colony of organisms can grow and become dangerous for consumption. Additionally, certain organisms can release toxins as a reaction to heat or other perceived threats. The presence of various bacteria and pathogens must be shown to be below the allowable limit of colony forming units per gram or not present in any amount depending on the organism’s suitability for human consumption. Check your state's laws on allowable limits.
