Food safety regulations in most states require that food workers replace gloves if they handle raw meat and switch to other foodstuffs.

But they don't generally require them to replace gloves between batches of (the same kind of) meat, or between different kinds of vegetables, or when switching from vegetables to meat, or between customers if they're on a service line. While it's recommended in those situations, I'm not sure any state mandates it.

I mean, they don't require gloves to be replaced in those situations because there isn't a good safety reason to. There's zero reason to replace your gloves when switching from dicing green peppers for a salad to picking up raw chicken. Or similarly between customers if you're just handling food, and not a cash register or anything. It's not like you're touching the customers...
