Detailed explanation-1: -Briefly, biological contamination is when food is contaminated with infectious bacteria (such as Salmonella spp. and L. monocytogenes) or toxin-producing organisms (such as Clostridium botulinum) and viruses (such as norovirus), which are a common cause of food poisoning and food spoilage.

Detailed explanation-2: -Salmonella can cause salmonellosis and typhoid fever and paratyphoid fever. Botulism is most often caused by Clostridium botulinum. Some other germs that cause foodborne illness include Cryptosporidium, Cyclospora, hepatitis A virus, Shigella, and Yersinia.

Detailed explanation-3: -Biological contamination refers to food that’s contaminated by substances produced by living creatures – such as humans, rodents, pests or microorganisms. This includes bacterial contamination, viral contamination or parasite contamination that’s transferred through saliva, pest droppings, blood or faecal matter.

Detailed explanation-4: -Biological contaminants include bacteria, viruses, animal dander and cat saliva, house dust, mites, cockroaches, and pollen. There are many sources of these pollutants. By controlling the relative humidity level in a home, the growth of some sources of biologicals can be minimized.
