Which of the following practices can be performed after slaughter?

The practice of checking for lesions is conducted after slaughter to ensure the safety and quality of the meat. This process involves inspecting the carcass for any signs of disease, infection, or abnormal conditions that could affect the health of consumers or compromise the integrity of the meat. This is a crucial step in meat inspection protocols and is performed by trained professionals to determine whether the meat is fit for human consumption.

In contrast, stunning the animal is typically carried out prior to slaughter as a means to render the animal unconscious and minimize suffering. Puncturing the lungs and tearing the skin are actions that are also associated with the slaughtering process itself, rather than practices done after the animal has been killed. Thus, the appropriate practice to perform after slaughter is indeed the examination for lesions, aligning with the goals of food safety and public health.
