Introduction
It is not recommended to consume Australian lobster that has been dead for more than 2 hours at room temperature. Australian lobster has tender meat rich in protein, but after death, bacteria inside the body multiply rapidly, breaking down nutrients and producing harmful substances. At room temperature, bacterial growth is extremely fast; within 2 hours, the meat quality may not have noticeably deteriorated, but beyond this time, there is a safety risk, and consumption may lead to gastrointestinal discomfort.
Generally, it is not recommended to consume Australian lobster that has been dead at room temperature for more than 2 hours. When refrigerated, this time can be extended to 6–8 hours, beyond which bacterial growth becomes more likely. If in doubt, freshness should be the primary criterion. Detailed analysis is as follows:
Australian lobster has tender meat rich in protein. After death, bacteria inside the body multiply rapidly, breaking down nutrients and producing harmful substances. At room temperature, bacterial proliferation is extremely fast; within 2 hours, the meat may not have noticeably deteriorated, but beyond this point, there is a safety risk, potentially causing gastrointestinal discomfort after consumption.
If promptly stored at 0–4°C after death, bacterial growth can be suppressed, extending the safe consumption window to 6–8 hours. However, even when refrigerated, the condition of the lobster must be carefully observed. If signs such as slimy texture, unpleasant odor, or discoloration of the shell appear, it indicates spoilage—such lobsters should not be eaten, even if the time limit hasn't been exceeded.
To ensure both taste and safety, it's best to slaughter and cook the lobster immediately after purchase. If temporary storage is needed, refrigerate promptly and strictly control the duration. Always inspect freshness carefully before consumption, and discard any spoiled lobster without exception. Ensure thorough cooking to minimize food safety risks.
