There’s lots of machinery involved in processing hay and silage into feed. Any broken part, such as the tine of a rake, could end up in the feed. There’s no good way of screening that out once it’s baled or in a silo/bag.
Of course it’s best to avoid contaminating areas with metal debris, but there’s still plenty of potential sources for contamination that aren’t feasible to elliminate.
Wow.
I’d prefer if they just swept the area with a large magnet regularly though. Or, y’know, converted to a farm maybe.
