Most food pantries including the Flemington food pantry allow you to go to the food pantry once per month or once every other month depending on the place and how much food the food pantry has available to distribute to people.
You can sometimes go to a different food pantry in your area or in another town to get more help with more food if you need more food.
However if you only have one food pantry near you and cannot get to another food pantry then it's usually just once per month or in some cases once every 2 months in some places.
I've been to food pantries that allow once per month and then another smaller food pantry that only allowed you to go to the food pantry every 2 months due to low food stock.
