This probably includes all stages of the food value chain. A good chunk will be at the farmer but in general their scale is big enough that they can redirect to animal feed. Or a it could be at the grocer who bought too much carrots and they are starting to wilt. But at this stage things are mixed up too much so more likely to be redirected for compost. Or it could be at the restaurant which gives you a big plate of food but you are full and don't take the rest home.
