I've tried our local KFC twice, dunno why twice, I guess everyone deserves a second chance, or maybe not so much with Jodi Arias or KFC. Needless to say I got a lot of reading done both times. You can trace down the culprit by going back about 12 hours, it takes approximately that long for the Salmonella (the most common food poisoning with poultry products) to fester.
Incubation Period - 12-72 hours
Symptoms - Diarrhea, fever, abdominal cramps, vomiting
Duration of Illness - 4-7 days
What Do I Do? - Drink plenty of fluids and get rest. If you cannot drink enough fluids to prevent dehydration or if your symptoms are severe, call your doctor. Antibiotics may be necessary if the infection spreads from the intestines to the blood stream.
