Kids Sick After McChickens - McDonald's,

My 2 kids, age 6 & 7, and myself all ate around 7p. I felt nauseous soon after eating and had diarrhea. An hour later both my boys (who ate mcchickens) almost simultaneously, started throwing up, had fever, & diarrhea. Took them to hospital where they said they believe they got food poisoning | Symptoms: Diarrhea, Nausea, Fever, Vomiting
