Which of the following statements about inspections of livestock is true?

The statement that all livestock must be inspected before slaughter is accurate and reflects the regulations in place to ensure food safety and animal welfare. In many countries, including the United States, federal regulations require that all livestock, such as cattle, sheep, pigs, and poultry, undergo inspection by a veterinarian or trained inspector before they can be processed for human consumption. This mandatory inspection process is designed to identify any signs of disease or distress and to ensure that the meat produced is safe and healthy for consumers.

The necessity of inspections before slaughter helps safeguard public health, as it reduces the risk of contaminated meat entering the food supply. Additionally, these inspections also serve to ensure that animals are treated humanely throughout the process.

Other options may misrepresent the situation regarding the mandatory nature of these inspections or suggest that their implementation varies based on certain conditions; however, the necessity for inspection remains consistent across the board for all livestock intended for human consumption.
