However, only 5% of cranberries sold are consumed raw. As such, you may wonder if you can eat them right out of the bag (3).
This article explains whether it’s safe to eat raw cranberries.
Cranberries are generally considered safe whether they are cooked or raw.
However, because of their notoriously bitter, sharp taste, most people prefer not to eat them raw or unsweetened.

If you have too many fresh cranberries, you can freeze them for up to a year. After cleaning, simply place them in an airtight container or bag in your freezer.
You can enjoy raw cranberries whole, juiced, or dropped into smoothies, baked goods, or other recipes that call for sharp-bitter notes.
How to find them
You can buy raw cranberries at some farmers markets when they are in season or purchase them frozen at your local grocery store.
Fresh cranberries contain pockets of air within the fruit’s membrane that gives them a little bounce when you squeeze them. This air also allows the fruit to float in bogs during harvesting.
