An employee at the Kansas State College of Veterinary Medicine brought me a present the other day: a bag of salad that apparently had a big wad of mud in it. Or was it poop? Smelled like mud.

She wasnt sickened by the food, but if you think a specific food has made you sick, here’s what to do:

• go to the doctor if necessary;

• keep the food, in the fridge or freezer if necessary; and,

• contact your local health department.

Bill Marler’s got some more specific guidelines here.
