Ensuring Seafood Freshness and Safety: Expert Tips

by Ella

Seafood is celebrated for its health benefits, yet it’s crucial to be aware of the challenges associated with its perishability and food safety, particularly when consumed raw. This report provides valuable advice to help you savor the advantages of seafood while minimizing the risks.

Risks of Consuming Raw Fish


From sushi and ceviche to oysters and clams, raw seafood is a culinary delight in various cuisines. However, when seafood is consumed raw, it poses distinct food safety concerns. Cooking seafood at 145 degrees Fahrenheit typically eliminates most harmful pathogens, but when consumed raw, these pathogens can remain present and cause illness.


For fin fish, parasites such as roundworms, tapeworms, and intestinal flukes are the primary concern. These parasites can potentially infiltrate the intestinal wall, leading to symptoms like nausea, diarrhea, or abdominal pain. Some may even migrate to vital organs like the liver or heart, causing severe damage.


For shellfish, especially oysters, clams, and mussels, bacteria, particularly Vibrio, is a common cause of food poisoning. Vibrio thrives in coastal waters, especially during warmer months, and can induce symptoms such as diarrhea, vomiting, and fever. Severe infections may necessitate hospitalization and could be fatal.


Safety Guidelines

Pregnant individuals, children under five, adults over 65, or those with weakened immune systems should avoid raw seafood.
When preparing raw fish at home, carefully select seafood and ensure it’s prepared properly.
For most raw fin fish, choose commercially frozen fish, as freezing at temperatures below zero degrees is essential to kill parasites. Thaw the fish slowly, and only use it if it remains cold and exhibits no signs of spoilage.
For raw shellfish, check for freshness, paying attention to the harvest date and the appearance of the shells.
When dining out at sushi or seafood restaurants, consider the establishment’s reputation based on ratings, reviews, and food inspection results.
Safe Shopping, Storage, and Preparation

Learn to recognize signs of spoilage in seafood, including odor, discoloration, and texture.

Don’t dismiss frozen fish, as it can be of high quality and less expensive.

Keep seafood separate from other groceries while shopping to prevent cross-contamination.

Store raw seafood properly to prevent contamination of other foods.

Freeze raw seafood if not using it within one to two days.

Thaw seafood slowly in the refrigerator or cold water.

Maintain a clean workspace when handling seafood and use separate utensils.

Ensure seafood reaches an internal temperature of 145 degrees Fahrenheit before consumption.

Refrigerate or keep seafood cold when serving.

Discard any seafood that raises doubts about its safety.

By adhering to these guidelines, you can savor the flavors of seafood while minimizing health risks and ensuring your culinary experiences remain enjoyable.
