I will never understand why many otherwise clean people don't wash their braai grills, assuming that "the heat from the fire will kill the germs".
I have no idea if the heat from a braai fire can kill germs, but I have severe gastroenteritis, and I suspect that I got the virus that caused it from an unwashed braaistand which had been lying on the floor for weeks.
It could just have been a coincidence that I got sick after the braai, but I cannot help but wonder if my discomfort could have been avoided if I had just avoided the meat.
