It's something I've had for as long as I can remember and I know my general anxiety is bad when I start getting really worried about food hygiene and also throw food out even if I've made a meal, if I feel it smells off, or is dodgy in some way. I've also bought food at cafes and then thrown them away if I get worried.
Restaurants can be a challenge, I always check the hygiene ratings, and don't order foods that can easily be dodgy, I also order fish etc well done...but I try to make myself eat out and do stuff..
The other thing that happens of course then is if I eat something that I decide after eating it that it was a bit dodgy, I will start to feel sick, need the loo etc, which I'm pretty sure is always just the anxiety.
Anyhow if you have it and found any solutions I'd love to know.
