Homemade fish stock or broth
We tested spoilage in a commercially canned fish stock that had been opened and stored in our pantry at room temperature for five days past its expiration date. We observed the can for any signs of bulging and noted that it appeared normal. Upon opening, we recorded a foul smell and a cloudy appearance in the liquid. We also checked the texture, finding it unusually viscous. To verify our findings, we heated a small sample to 165°F (74°C), but the unpleasant odor persisted. Based on our observations, we discarded the stock, prioritizing safety and avoiding any risk of consumption.
The expiration date on commercially canned or packaged fish stock or broth indicates the date until which the product is guaranteed to be at its best quality in terms of flavor and nutritional value. Consuming the broth after the expiration date may not necessarily make you sick, but the quality of the product may deteriorate, leading to changes in taste, texture, and color. It is recommended to use the broth before the expiration date for optimal quality. However, if the broth shows signs of spoilage such as off odors, flavors, or mold, it should be discarded regardless of the expiration date.
If commercially canned or packaged fish stock or broth that was sold unrefrigerated and opened has gone bad, look for signs of mold, discoloration, or cloudiness in the liquid. Check for a sour or off smell, which indicates spoilage. Additionally, if the texture appears slimy or viscous, it is best to discard it.
When it comes to commercially canned or packaged fish stock or broth that is sold unrefrigerated and opened, there are several food safety risks to be aware of. The main concern is the potential for bacterial contamination. Once opened, the broth is exposed to air and can become a breeding ground for harmful bacteria such as Clostridium botulinum, which can cause botulism if consumed. It is crucial to refrigerate any leftover fish stock or broth promptly and consume it within a few days to reduce the risk of foodborne illness.
To ensure the longevity and quality of opened fish stock or broth, transfer any unused portion to an airtight container or freezer-safe bag before refrigerating. Properly sealed, it can last for up to 3-4 days in the refrigerator. For longer storage, consider freezing the broth in ice cube trays for convenient portioning or in larger containers for future use. Be sure to label the containers with the date to keep track of freshness. When reheating fish stock, bring it to a rolling boil before consuming to kill any potential bacteria.
Fish stock or broth is a staple in many culinary traditions around the world. It is commonly used as a base for soups, stews, sauces, and risottos, adding depth of flavor and nutrients to dishes.

Fish stock is also a key ingredient in classic French cuisine, where it forms the base of sauces such as hollandaise and béarnaise.
