When refrigerating raw shrimp, it’s crucial to label the container with the date and use them within a day or two, as they are highly perishable. Additionally, always handle raw shrimp safely by washing your hands thoroughly before and after handling them, and make sure to cook them to an internal temperature of at least 145°F (63°C) to ensure food safety. By following these tips, you can help maintain the quality and freshness of your raw shrimp and enjoy them at their best.
Can I leave cooked shrimp out at room temperature?
It’s generally not recommended to leave cooked shrimp out at room temperature for an extended period, as this can pose a risk of foodborne illness. According to food safety guidelines, cooked shrimp should be stored in the refrigerator at a temperature of 40°F (4°C) or below within two hours of cooking. Leaving cooked shrimp at room temperature can allow bacteria like Staphylococcus aureus and Vibrio vulnificus to multiply rapidly, potentially causing food poisoning. To keep cooked shrimp safe to eat, it’s best to refrigerate or freeze it promptly, or discard it if it has been left out for too long.
