In theory yes, although in practice many patient I see who get
staphStaph aureus food poisoning (short for staphylococcus, a kind of germ) infections weren't exposed to anyone or anything that would explain it.
StaphStaph aureus food poisoning germs live on our body and sometimes cause trouble, so the infection doesn't have to come from outside. But it is possible to spread it, so if someone nearby gets a suspicious eruption, they should of course check it out.
Best.
