if they were frozen, you can absolutely get food poisoning from it. frozen food gets thawed out sometime when being moved from place to place in the grocery stores, manufacturing, and shipping. being thawed out and refrozen is a real risk, and bacteria can grow on those food items regardless of whether or not the item itself is usually safe raw (like non-greened potatoes).

that's why a lot of frozen food packaging still says to cook to 165, even for vegetables and other things you eat raw all the time.
