If you find suspicious material, do not rely on cooking alone to resolve every concern. Separate the fish from other foods, avoid cross-contamination, and ask a qualified professional whether it should be discarded or assessed further.
Chapter 4: How to Recognize Fresh Fish and Handle It Safely
Freshness is an important consideration when buying and preparing seafood. Although no single sign guarantees safety, several practical checks can help consumers make better decisions.
Fresh whole fish often have clear, relatively bright eyes, moist skin, and flesh that springs back when gently pressed. The smell should be mild and characteristic of fresh fish rather than strongly sour, rancid, or ammonia-like. Gills may appear red or pink in many species, although their appearance varies.
Fish should be purchased from a reputable seller and kept properly chilled. If you are transporting seafood home, minimize the time it spends at warm temperatures. Refrigerate it promptly, ideally at 40°F (4°C) or below, and follow local food-safety guidance for storage.
During preparation, wash your hands before and after handling raw fish. Use clean utensils and cutting boards, and keep raw seafood separate from cooked food, salads, and other ready-to-eat items. Clean and sanitize surfaces that have come into contact with raw fish.
Do not wash raw fish in a way that splashes contaminated water across the kitchen. Instead, focus on safe handling and proper cooking.
If a fish has an unusual odor, deteriorated texture, or unexplained internal material, do not assume that removing the suspicious part makes the rest safe. When its condition is questionable, discarding it is the safer choice.
These precautions apply whether you buy fish from a supermarket, a traditional market, or a local fisherman. Good handling reduces risk, but it cannot guarantee that every fish is free from contamination.
