Can I eat the leftover spicy crab the next day if I didn't finish it?

Generally speaking, whether leftover spicy crab can be consumed the next day depends on the storage method and its condition. If it has been properly sealed and refrigerated without signs of spoilage, it may still be safe to eat; however, if left at room temperature or already spoiled, it should not be consumed. The details are as follows:

If the leftover spicy crab is promptly placed in an airtight container and refrigerated at 0–4°C, and shows no unpleasant odor, maintains firm flesh, and has no slimy texture the next day, it is generally safe for consumption. Refrigeration helps inhibit bacterial growth, while sealing prevents cross-contamination and odor absorption. Before eating, the crab should be thoroughly reheated until fully hot to eliminate any potential bacteria that may have developed.

If the leftover crab was not sealed and left at room temperature for more than two hours, or if it develops a sour or stronger fishy smell, soft and mushy texture, slimy surface, or cloudy sauce by the next day, it should not be eaten. Crab meat is tender and high in protein, making it particularly susceptible to bacterial growth at room temperature, which could lead to gastrointestinal discomfort if consumed.

When enjoying spicy crab, consume in moderation. Any leftovers should be promptly sealed and refrigerated, and not stored for more than 24 hours. Ensure crabs are fully cooked during preparation, and always choose live, fresh crabs when purchasing.
