It’s That Time of Year Again

It’s a few days after a major holiday (Memorial Day in the United States), and clinical microbiologists knows what that means. It’s foodborne illness season! According to the CDC, Norovirus and Salmonella are the biggest culprits, but several organisms can be implicated.

If your lab doesn’t recover Salmonella, Campylobacter, or E. coli O157:H7 often, consider brushing up on the identifying characteristics of these organisms. (Do you know which one doesn’t ferment sorbitol?) It’s also helpful to keep the patient history (in particular, their travel history) in mind when reading enteric cultures or performing a microscopic ova and parasite examination. Also, now is a good time to be sure your reporting procedures (including local public health contact information) are up to date.

Check out the CDC’s website for more information on foodborne outbreaks, including how many people are affected.
