Grocery stores often donate food they no longer need or can't sell to local food banks. what problems might this create for the food banks?

the food they are giving to the fodd banks may be rotten or old and may be un eatable and some people may be allergic to the food.

Explanation:

Most of the stuff is already past the expiration date, and can or is rotten and not edible at all. People can also get sick or die from the un-kept condition of the food. For example, steaks that are past their expiration date 2 months ago but have not been refrigerated but given to a less fortunate family. That could cause food poisoning a type of reaction or on set seizures.

Explanation: The types of stuff in the food, or the place that kept it could have not been in good conditions. They could have been left out for other animals "rodents" to take action on. The food or beverages, could also have been tampered with such as putting preservation chemicals into them even though they are not needed. The food banks could be sued or not used anymore which means millions of less fortunate people would not have food if there is not another one out there (close to them).
