This sort of thing still happens
I’ve had a chat with a farmer in Australia where they were feeding dariy cows boiled sweets (He got access to some sort container load of factory seconds, still with the plastic on, farmer wasn’t going to remove the plastic from millions of boiled lollies)
Ok wow didn’t realise it was that wide spread. These were just some locals talking about stuff and he was proud they had gotton a good deal on seconds sweets. Feeding left over stuff, bread, cakes, seemed common place.
I was horrified about the plastic but seems to be pretty normal!
