Times are for unopened, properly stored herring and reflect best quality. Always use your senses and follow any date on the package.
Signs herring has gone bad
- Strong fishy, sour, or ammonia smell — fresh seafood should smell of the sea, not 'fishy'.
- Slimy coating, dull eyes, or flesh that no longer springs back when pressed.
- Discolouration or a sticky surface.
When in doubt, throw it out — the cost of a spoiled meal isn't worth the risk.
Best way to store herring
Seafood is highly perishable — keep it on ice or in the coldest part of the fridge and cook within a day or two. To freeze, wrap tightly and freeze fast; thaw in the fridge, never on the counter.
