Enjoying Grilled Mackerel Safely During Summer

During the hot and humid summer months, it's crucial to be extra cautious with seafood that can spoil easily. While many are aware of the risks of eating raw fish and oysters in the summer, it's less commonly known that even when cooked, certain oily fish like mackerel, saury, and tuna can still pose a risk.

The Dangers of Oily Fish

Oily fish are particularly susceptible because their red flesh contains a high concentration of an amino acid called histidine. When these fish are exposed to warm temperatures, bacteria rapidly multiply and convert histidine into histamine. This process happens surprisingly quickly; oily fish left at room temperature during summer can become problematic in as little as an hour.

Histamine poisoning often presents symptoms similar to food allergies. Typically, within 10 minutes to 2 hours after consuming contaminated fish, you might experience flushing of the face, neck, or chest, along with rashes, hives, nausea, and a tingling sensation in the mouth. Importantly, once histamine is formed, it cannot be destroyed by high-temperature cooking, so caution is essential.

How to Safely Eat Mackerel

When buying mackerel in the summer, don't solely rely on the expiration date. It's safer to avoid products that have been sitting out at the front of display shelves in supermarkets or markets. If possible, opt for salted mackerel (gango-deungeo), which has had its guts removed and been seasoned with salt, rather than fresh, whole fish. After purchasing, refrigerate it immediately and aim to cook and consume it as soon as possible.

• It's safest to cook mackerel within the same day or the next day during the hot and humid summer months.
• To minimize temperature fluctuations, store seafood deep inside the refrigerator rather than near the door, which is opened frequently.

Limitations of Freezing

Freezing isn't a foolproof solution either. Freezing doesn't kill bacteria but rather slows their growth. Over extended periods, a decline in taste and quality is inevitable. Fish with high fat content, like mackerel, should not be stored frozen for excessively long periods; it's best to consume them within 3 months if possible.

Conclusion

To safely enjoy grilled mackerel in the summer, choosing fresh ingredients and proper storage are key. Use these tips to savor delicious and safe seafood dishes all summer long!
