Which three primary categories of contaminants are monitored by agencies like the FDA in animal feed safety assessments?
Answer
Biological Contaminants, Chemical Contaminants, and Physical Contaminants
The safety monitoring performed by agencies like the FDA for animal feed is structured around identifying three main categories of risk. Biological contaminants encompass living or microscopic threats such as dangerous mycotoxins produced by molds or zoonotic pathogens like Salmonella bacteria or viruses. Chemical contaminants specifically refer to substances like residual veterinary drug residues that may remain from animal treatments. Physical contaminants involve any unwanted foreign materials introduced accidentally during the complex processes of milling, handling, or storage, which present potential physical harm upon ingestion.
