There are three types of microorganisms that can contaminate fresh produce: Bacteria, Parasites, and Viruses. Between 1996 and 2014, there have been 148 FDA Outbreaks linked to bacteria, 21 outbreaks linked to viruses, and 3 outbreaks linked to parasites.
Bacteria
- Microorganisms that can multiply both inside and outside of a host
- Good Agricultural Practices can minimize situations that support bacterial survival and growth
Viruses
- Small particles of nucleic acid that only multiply in a host
- Only a few particles will make someone ill
- Usually spread by individuals who have not washed their hands before touching produce
- Prevention is key to reducing viral contamination
Parasites
- Protozoa or intestinal worms that only multiply in a host
- Can survive in the body for a long time without producing any symptoms
- Usually transmitted through water, and often not killed by chemical sanitizers
