Enzymes are not considered a type of pathogen. Pathogens are microorganisms that can cause disease, and they primarily include bacteria, viruses, and fungi. Each of these pathogens has the capacity to invade hosts and lead to illnesses, affecting human health and food safety.

Bacteria, for instance, are single-celled organisms that can reproduce rapidly and can lead to foodborne illnesses such as Salmonella and E. coli. Viruses, which are even smaller than bacteria, require a host cell to reproduce and can cause diseases like norovirus and hepatitis A. Fungi, which include yeasts and molds, can also spoil food and cause foodborne illnesses.

In contrast, enzymes are biological catalysts that speed up chemical reactions in various processes, including digestion and fermentation. While they play significant roles in food preparation and preservation, they do not cause disease themselves. Understanding this distinction is vital in food safety contexts, as it helps in identifying and controlling risks associated with foodborne diseases.
