What would you use to test for pathogens in food?
Testing for pathogens
One is plating food samples on agar plates and watching for the growth of bacterial colonies, which may take several days. This process can be accelerated using chromogenic agar and proper enrichment procedures—tools offered in kits such as Bio-Rad’s rapid chromogenic-agar assays.
What are two examples of viruses that can cause foodborne illness?
Other important bacteria and viruses that cause foodborne illness include: Bacillus cereus. Botulism. Hepatitis A.
Bacteria and Viruses
