Child ate chicken nuggets in restaurant that slight undercooked some pink inside. was told they defrosted properly before cooked. risk of getting sick?

Low risk but: If your son feels well, does not have fever, chills, vomiting, diarrhea or cramping abdominal pain you are ok. The infections that can be transmitted through undercooked poultry include campylobacter, salmonella, enteropathogenic e-coli, and norovirus, Commercially sold poultry is closely managed by the USDA but there have been occasional reported outbreaks of salmonella from chicken that was frozen, suggesting the freezing process does not render salmonella non infectious. Should there be a risk, there will surely be enough affected members of the community to trigger an investigation.
