When handling swordfish, always use clean utensils and cutting boards, and wash your hands thoroughly before and after handling the fish.
When storing swordfish, it’s essential to prevent cross-contamination with other foods. Keep swordfish separate from other foods, and use a clean cutting board and utensils when preparing it. If you plan to freeze swordfish, make sure to wrap it tightly in plastic wrap or aluminum foil and label it with the date and contents. Frozen swordfish should be stored at 0°F (-18°C) or below.
Can I eat swordfish if I’m pregnant or breastfeeding?
Pregnant women and breastfeeding mothers should avoid eating swordfish due to the high levels of mercury it contains. Mercury can harm the developing fetus’s nervous system and brain development, and it can also pass into breast milk, posing a risk to the baby. The FDA and EPA recommend that pregnant women, breastfeeding mothers, and young children avoid eating swordfish and other high-mercury fish altogether.
However, it’s essential to note that not all fish are created equal, and some types of fish are safer to eat during pregnancy and breastfeeding. Fatty fish like salmon, sardines, and anchovies are rich in omega-3 fatty acids and low in mercury, making them a safer choice. If you’re pregnant or breastfeeding, consult with your healthcare provider or a registered dietitian to determine the best fish choices for you.
How can I cook swordfish to minimize food safety risks?
Cooking swordfish to the recommended internal temperature is essential to minimizing food safety risks.
