Someone sent me tuna in olive oil from a delicatessen shop via post in a box. When I received the package the safety button of the jar was off (you could squeeze it). Due to this I was hesitant to eat it but when I opened it there was no bad smell and put it in the fridge immediately.
My question is, assuming that it was kept in room temperature during transit for about 3-4 days with the safety button in the jar released is it safe to eat it ?
Does fish stay fresh in olive oil even in room temperature ?
It is a really expensive and tasty product and I just don't feel like throwing it away.
