My son just ate a Hershey's Kiss that contained maggots. Unfortunately, he did not realize it until he unwrapped the second one and was able to see maggots actually crawling in and out of it. He realized he had something in his mouth still, and spit out a maggot. We are looking for some guidance on what to do, what to watch for, any possible adverse effects possible from this ingestion, basically need reassurance for his mental well-being. Thank you for your assistance.
