How can you tell if a frozen lobster is bad?

To determine if a frozen lobster is bad, check for any signs of freezer burn, such as dry spots or discoloration, which can affect taste and texture. Additionally, if the lobster has a strong, off-putting odor when thawed, it's likely spoiled. Ensure that the packaging is intact without any tears or leaks, as this could indicate contamination. Lastly, if the lobster has been stored for an extended period beyond its recommended freezing time (typically up to 12 months), it may not be safe to eat.
