Food Safety Reports: Jack in the Box, Kipapa Drive, Mililani, HI, USA

Ate a chicken salad and my kids had slight fever and was throwing up and could not hold no food down. Next day i hear my friends daughter ate chicken salad from a different jack in the box and she too had the same symptoms as my sons. Could some thing be wrong with the chicken or the salad?  | Symptoms: Diarrhea, Fever, Vomiting
