Bests & Worsts Reviews from Amazon

This is my first time purchasing this because based on my research this is the healthiest tuna can I can find. I was excited to try this, after opening 4 cans and while eating them, I chewed on this tiny piece of plastic. I was horrified by this. I had the throw away the rest, and I am not sure I safe I feel about eating the rest of the box. I am very disappointed by this. I don't know if anyone else experienced this, but something in the manufacturing process was overlooked.
