Human bodies are not meant to eat raw meat.
And eating Raw Chicken can certainly harm you by infecting you with Salmonella, E Coli and also an illness called campylobacter.
These things can be fatal if you're not treated.
Symptoms of this illness and food poisoning from eating Raw Chicken are Vomiting, Diarrhea, Fever and Abdominal Pain.
Always cook chicken fully before eating it to kill off bacteria and prevent you and your family from becoming sick and potentially dying as a result.
