re-post of mine ....
"Best Before" dates are generally intended as a guide and are generally only critical in fresh produce. With processed foods that are properly stored these dates become much less important. Obviously for best results, the fresher the food, the better. (food does not last forever)
How long the food is good for mostly depends on how the food has been stored. Provided that it has been kept in a tightly sealed container so that moisture is not an issue, it has not been exposed to sunlight, or prolonged high temps, there should be no serious changes to the overall quality of the food. Some vitamin content will be lost, but this should not cause any major problems. The biggest problem with some fish foods, especially those higher in fat content, is the changes to fatty acids due to oxidation which can lead to rancidity over time. This generally tends to make the foods unpalatable and fish will refuse to eat it. If it smells ok, and you don't see any issues with mold, it should be ok. Just feed it all in a relatively short period of time after the container is initially opened.
In this case (stored in freezer) the food should be fine, but even when frozen there will be some nutrient loss over time.
