Do they (Aldi -- sell questionable food)? 
Of course. Most stores in this country seem to have extremely low health standards. Theyll sell whatever falls off the truck.
And at Iceland, you can get some great deals on frozen hair currys. They're called "beef curry" but after eating about 10 of them, I can confirm that "hair" should definetely be in the ingredients list.
The first time I picked a hair out of it I said "well...maybe it's one of mine (even though it was a somewhat long hair and my hair is very short)"
The second time I figured "well...maybe it just somehow flew in here"
But by the third time (third consecutive time, I should point out) I knew that it was a hair that originated from the manufacturer. I'm not sure if it's animal hair or human hair and Im also not sure which I'd prefer. But its extremely hairy curry that they sell. I cant believe theyre allowed to sell this sh*t. Really, the quality control for food in this country must be absolutely zero.
It's also extremely low-grade, probably not entirely safe-to-eat beef.
