Foodborne pathogens mostly bacteria and fungi but also some viruses prions and protozoa contaminate food during production and processing but also during storage and transport before consuming. The symptoms of a foodborne illness vary depending on which illness a person has. There are several factors that can contribute to the symptoms and severity of.

Methods for rapid detection of these pathogenic bacteria are important in order to avoid contamination of food. -can contaminate water and many types of food. Foodborne illness occurs when people eat or drink food or beverages contaminated with pathogens chemicals or toxins.

Chemical microbial physical and allergenic. Mold A fungi that can produce a dangerous toxin. Stationery phase--keep growing until conditions are unfavorable.

Pathogens can also be spread via contaminated food and water. They are E coli Hepatitis A Nontyphoidal Salmonella Norovirus Shigella Salmonella Typhi. All food is at risk of contamination from these four types.
