When visiting the store, it\u2019s easy to choose individually wrapped frozen fish. There\u2019s much to like about the packaging. They are easy to store and prepare. Cooking also is a breeze too since everything is pre-cut and portioned out.<\/p>\n\n\n\n
The vacuum-sealed packaging, also known as Reduced Oxygen Packaging (ROP), prevents water loss and the fish from drying out. It\u2019s designed to minimize odors and thus extend shelf life. But what if there was more than what meets the eye?<\/p>\n\n\n\n

This health risk is known as botulism.<\/p>\n\n\n\n What is botulism?<\/strong><\/p>\n\n\n\n Shutterstock<\/p>\n\n\n\n The CDC defines botulism as a \u201crare but serious illness caused by a toxin that attacks the body\u2019s nerves.\u201d Symptoms initially involve weakened muscles. However it can lead to difficulty breathing and even death. Botulism is most commonly associated with canned goods, but the risk also presents itself with vacuum-sealed packaging.<\/p>\n\n\n\n Why does this happen?<\/strong><\/p>\n\n\n\n Shutterstock<\/p>\n\n\n\n Clostridium botulinum is an anaerobic bacteria. It produces spores that grow in warmer, low-oxygen conditions. These spores then can release the toxin which results in botulism. In other words, when you remove the frozen package from the freezer and the temperature rises, the risk of this happening increases rapidly.<\/p>\n\n\n\n How do you prevent this from happening?<\/strong><\/p>\n\n\n\n Luckily, there are a series of simple tips to prevent this from happening.<\/p>\n\n\n\n 1. Properly store frozen fish<\/strong><\/p>\n\n\n\n Shutterstock<\/p>\n\n\n\n Make sure you freeze the individual packets of vacuum-sealed fish at the right temperature. The risk of botulism increases dramatically at temperatures above 38\u00b0F. Many home refrigerators do have temperatures above 38\u00b0F, so you\u2019ll want to be sure you to check yours.<\/p>\n\n\n\n 2. Remove the fish from packaging before thawing<\/strong><\/p>\n\n\n\n Shutterstock<\/p>\n\n\n\n Why is removing the fish so important? Remember, the vacuum-sealed packaging eliminates oxygen. You want to expose frozen fish to oxygen to prevent the spores from producing toxins in the first place.<\/p>\n\n\n\n 3. Follow thawing guidelines provided by seller<\/strong><\/p>\n\n\n\n Shutterstock<\/p>\n\n\n\n As always, follow the thawing recommendations provided by the seller. By itself, vacuum-sealed fish is not a shelf stable or commercially stable product, meaning it requires refrigeration.<\/p>\n\n\n\n
