Good morning, Last night I cooked a pickled pork I purchased from the supermarket. I prepared the food as instructed etc. All went well until the 3rd bite into my roll to which I received a sharp pain in my gum. I found a bone shard in my roll from the pickled pork which cut my gum. Pain was short lived last night though today I have discomfort from my gum in the spot the bone shard cut. Are there grounds for negligence here on the food preparation side of the supermarket? Thanks in advance.
