I've read Humphrey Bogart avoided illness during the filming of Africa Queen due to his vast quantities of alcohol consumed. I've heard ceviche is safe to eat due to being marinated in lime juice (acidic). I've also heard similar properties of hot sauce.
Barring control over safe food handling, food freshness and temperatures, are there any hacks to help avoid food borne illness when on the road? Will drowning my dirty taco in Mexico with lime help? Will a shot or two with my meal help?
