When properly stored, vacuum-sealed salmon can last in the refrigerator for about 2-3 days past its printed expiration date. However, it's important to note that this is a general guideline, and the actual shelf life can vary depending on factors such as the freshness of the salmon before vacuum sealing, the quality of the vacuum seal, and the temperature of your refrigerator.
Considering you've had the vacuum-sealed salmon in the fridge for one week, it is beyond the recommended time for safe consumption. While a lack of bad smell is a positive sign, it's not a foolproof indicator of freshness or safety. The quality and safety of the salmon can deteriorate even without a noticeable smell.
To ensure food safety, it's best to follow the recommended storage guidelines and discard the salmon if it has been in the refrigerator for longer than the suggested time. Consuming expired seafood carries the risk of foodborne illness, such as bacterial contamination, which can cause symptoms like nausea, vomiting, diarrhea, and abdominal pain.
To prevent potential illness, it is generally advisable to err on the side of caution and avoid consuming seafood that has been stored for an extended period beyond the recommended time.
