Microbiome research is an area of increasing interest in livestock production due to potential microbiome impacts on animal performance. The term microbiome, while scientifically rooted in the genetic makeup of the microbes, is used to more generally represent the microbial populations that are present in an environment.
The meat industry uses refrigeration as the air-chilling system to slow microbial growth and maintain carcass quality. In the pork industry, the time between harvest and fabrication is typically 24 to 48 hours.
