Naaaaaah. It's all overblown hype. I've eaten things things (literally I was unaware of the species of meat I was consuming) that would make a billy goat puke and in conditions that would make a gorilla retch. All over the world. I was never ill. I avoided dysentery by using the little purification pills provided by my wise old Uncle Sam and everything was fine. Take reasonable precautions and live your life to the fullest extent. I mean safety is nice....but it's not first. LIFE is first and life....is....not....safe.
That's a good attitude. I remember when I was a kid in Brooklyn picking up someone else's cast-off bubble gum off the sidewalk and putting it in my mouth--and enjoying it!
And I'm still around, some seventy years later. ;)
