You'll need a penicillin shot.
Isn't that what he's processing right now?
In truth - there's not much you can do, iirc, except some medical professional assistance if it gets way out of hand.
Most food-borne molds aren't going to do anything except give you a decent case of "food poisoning" - except, it'll likely be far more acute than a bad case of true bacterial food poisoning.
Your stomach can usually break down mold pretty well, and active fungus growth is easier for the body to kill than spores. Most of the most dangerous mold toxins are delivered by spores that survive the body - spores are usually extremely hardy, so they pass through the worst of the body's defenses, survive long enough to grow into their full selves, and delivery their toxins.
Most fully-capable fungus specimens can't survive the body long enough to deliver the toxins that harm us most at the point in our digestive tract the toxin is most likely to survive.
If anything, you might have a bout of nausea and the runs, but if you've ever had a bad case of food poisoning, it probably won't come close to matching that.
If it does, pay close attention - bad cases of toxin ingestion or even mold allergies, will require treatment.
You could also experience seemingly non-food-borne illness. If it seems you're head is in bad shape, like you're all kinds of confused and or have weird twitches, call a doctor immediately. Could be odd reaction but nothing important, could be an emergency.
You could also get hives and otherwise display signs of an allergic reaction.
Take allergy meds, pay close attention, and its probably still a good idea to call a doctor even as your reaching for those allergy meds. Consuming mold and displaying signs of mold allergies aren't everyday occurrences, so who knows how it'll progress and in what time frame.
