Animals harboring the micro organism often don’t appear sick, mentioned Dr. Francois Watkins.
When livestock are butchered, the micro organism of their intestines can contaminate the meat. One out of every 25 packages of rooster bought at grocery shops incorporates salmonella, in response to the C.D.C.

Some folks develop reactive arthritis after salmonella infections and expertise joint ache, eye irritation or painful urination that may persist after the an infection has cleared.
