Best Question:

Do we need to report an employee who tested positive for a non-shiga-toxin-producing (non-STEC) E.coli? 


This question is much more complicated to answer than it should be, and it's heavily influenced by the exact city and state where the person works. 

‍

It’s not nearly as concerning from a foodborne illness perspective if an employee tests positive for a non-STEC E. coli. The worst outbreaks are generally from E. coli O157:H7 or other STECs. California is one example of a state that only requires reporting for STEC, also known as enterohemorrhagic (EHEC) or vero-toxin producing (VTEC). 

‍

For some state and county health departments, all E. coli cases are reportable, but different health departments respond differently to non-STEC E. coli. If the employee had GI symptoms and tested positive for E. coli, you should assume that there’s a foodborne illness risk and act accordingly, but it may not require the same level of response (or panic) as O157:H7, for example. 

‍

In short, be prepared for a call or visit from your health department, but rest assured that you probably don’t need to report it. If required in your state or jurisdiction, the lab that did the testing will report it to the health department. There are some situations where we might advise you to proactively call, but those are fewer and further between. When in doubt, give ZHH a call and we can support you in figuring out the right next steps with the sick employee and the health department.
