What do you call a term someone savoured and defiled a bit of food and left it

Question

We Indian don't eat food that was eaten by someone else. For example:

• If someone has taken or tasted a little pizza and left it then we do not eat it. We call it जूठा . I am looking for the word in English that the food was eaten a bit and left

Answer 1

I don't know if English has a word specifically for that, but the first word that came to my mind is touched:

I wouldn't eat the omelet. It's been touched.

In this context, word touched doesn't mean the omelet was necessarily touched by the fingers or a hand; it is speaking more about being touched by utensils during the act of eating. Or, as the dictionary says:

touch (trans. v.) To eat or drink; taste : She didn't touch her food.

In conversation, the word might be used like this:

Stan: Ew, Dan, why are you eating her hamburger?
Dan: Why not? She didn't touch it.

You can also use untouched as an antonym:

Do you want to eat my fish? It's untouched.

Answer 2

That could be said in several ways in English. Leftovers is the term for food made in abundance and eaten at a later time. Usage: "There was too much pizza so I'll have to eat the leftovers tomorrow."

A word with a slightly negative connotation is the term scraps, which means the undesirable part of food left uneaten or also the part of the food defiled by the first person who ate from it. Scraps may be something you would give your dog after you've eaten all you wish from your plate. Usage: "He picked off all the pepperoni and cheese from the pizza and left me with the scraps."
