There has been a marked shift in consumer preferences about food choices. Today, consumers not only demand safe, inexpensive, tasty, and healthy food but also expect animal welfare and environmental safety. Consumers have become more curious about the source of meat—whether it comes from a conventional or an antibiotic-free farm (ABF) and if biosecurity requirements were met. To ensure the supply of safe meat to consumers, preventive measures need to be taken at the farm when animals are alive. This is where the concept of preharvest food safety comes from. Preharvest food safety is the combination of measures and interventions adopted at the farm to detect harmful pathogens and to reduce pathogen load in the food chain. Preharvest food safety is not only about the food animals and the microbes they carry but also includes the surrounding environment and human activities. The farm is a dynamic environment where pathogens, food animals, human interventions, environmental factors, and other animal species interact closely.
