Bleugh.
This is why I dread the BBQ season, because of habits like this.
@zingally :
We used to live in caves ffs. And no-one knew what food hygiene even was, until, what? 100 years ago? Funnily enough, the human race survived
The human race, survived, yes, but individuals had a pretty low chance of surviving. When in caves everyone was pretty much dead by age 30, later infant and maternal mortality was sky high, throughout the middle ages and Tudor times and beyond people regularly died from hygiene related illnesses such as cholera, typhoid and dysentry. Look at deaths from puerperal fever on maternity wards until Ignaz Semmelweiss discovered that hand washing was important!
Plus we did not raise chicken in intensive and battery conditions where disease is rife.
Your point really is not valid.
Lots of people do follow these lazy practices, and it's fine. But when it does hit unlucky and transmit salmonella, campylobacter or EColi the results are extremely painful, long lasting, and dangerous to anyone vulnerable.
