We've all had it. It only lasts about 24 hours, but it is miserable and not treatable.
It's not treatable because the Staph bacterium (Staphlococcus aureus) produces a toxin which causes the physical reaction. The toxin is the problem, not the Staph. Staph is everywhere.
Food poisoning is avoidable by proper food management. Specifically, don't leave susceptible foods out of refrigeration for more than 2-3 hours. Yes, I know, we all do sometimes but it's not "best practices."
My last food poisoning incident was from a shrimp dish.
