Is it safe to eat red crabs?

The red crab typically refers to the Australian red crab, which is generally not edible as it may lead to poisoning and unnecessary bodily harm. The Australian red crab contains a certain level of toxicity, including special formic acid, which may cause damage to the gastrointestinal mucosa upon consumption. This can result in obvious abdominal pain and potentially trigger food poisoning. Especially for patients with gastric ulcers, consuming it may exacerbate their condition, leading to symptoms such as hematemesis and melena. Even normal individuals may experience abdominal discomfort after ingestion. Therefore, it is not recommended for consumption. If obvious symptoms of discomfort appear after ingestion, such as upper abdominal pain and appetite loss, it is necessary to use medications like Omeprazole Enteric-coated Capsules, Rabeprazole Sodium Enteric-coated Capsules, and Colloidal Bismuth Pectin Capsules under a doctor's guidance to reduce the irritation to the gastric mucosa. When necessary, gastric endoscopic surgery can be performed to facilitate the recovery of the gastric mucosa. In daily life, it is important to maintain a light diet, chew food thoroughly, and avoid overeating. Additionally, one should pay attention to regular meal times throughout the day. If other symptoms of discomfort appear, standardized treatment should be sought promptly.
