Maybe calculated tariffs on commodities where companies are contemplating outsourcing, but that's a step you take in advance in order to dissuade their action. This is like making the whole school sit with their heads down through recess because one specific kid was unruly.
Edit: There wasn't even an unruly kid. The Principal is just vindictive, has a hangover, and hates children.
The fungus you're thinking of is likely ergot, because it shows up in pretty large volume in batches of rye.
In processing, it ends up as a dark purple/black dried up mass that assumes kinda a crescent shape. Mills will run a batch of rye through a color-sorter - a bunch of times consecutively - to reduce the amount of ergot in the batch before milling.
You can technically refine it into LSD, but if you screw up, you can kill people. (Morning Glories are the preferred method).
The number of 55-gallon drums of ergot I've disposed of, though... It's difficult not to identify with Walter White and wonder... "what if?"
I mean, not for a lot of food production. We had Halal cert at our grain mill and a few other places I've worked at, and we never treated the food differently. Same with Kosher. They just send someone out to extort your business for certificate renewal.
Do you think it's conspiracy theories that turn people gay and they're just trying to justify it so they can feel comfortable with their sexualities?
