Expired canned food is recommended to be best not to eat, because the canned food will certainly be added inside some preservatives, although that still looks good, not bad, but in fact the food is already spoiled.
Generally, canned pangasius with black beans can only be kept at room temperature for 1 to 2 days after opening, if you want to keep it for a longer time, you can seal it with plastic wrap and put it in the refrigerator.
