What characteristic distinguishes spoiled lobster from gummy undercooked lobster?

Answer

Slimy texture or an off-putting odor

It is important to differentiate textural issues arising from incorrect cooking time (undercooked vs. overcooked) from issues related to spoilage, which involve bacterial growth and safety concerns. Undercooked lobster manifests as a gummy or slightly rubbery texture due to incomplete protein setting, and it might appear translucent. Spoiled lobster, however, presents different sensory signals. If the meat is old or compromised by bacterial activity, it will typically exhibit an undesirable slimy texture that feels different from the density of undercooked flesh, and it will usually be accompanied by an off-putting or foul odor. While both states are undesirable, spoilage indicates a direct safety hazard beyond mere palatability issues caused by insufficient heat.
