often cause non-specific symptoms (diarrhea, lethargy) that are self-limiting
can result in chronic diseases making dx difficult
infectious dose
the amount of an organism that is required to cause illness
zero tolerance

does NOT mean that no bacteria can be found in food
is it possible to completely eradicate microbes from the food supply
no

- beef
- produce

- dairy
what viruses are transmitted via food
- hepatitis A

does the USA use active surveillance for E. coli
yes - active surveillance of STEC (shiga producing E. coli)
