SPRAYING a mixture of 29 benign bacterial species on newly hatched chicks subtantially lowers the risk that they will become colonized with Salmonella, an important cause of food-borne infections, according to federal officials.
The new strategy, which was developed by researchers at the US Department of Agriculture (USDA), was approved by the Food and Drug Administration (FDA) last month. According to the FDA, an estimated 2 million to 4 million cases of Salmonella poisoning occur in the United States each year, most resulting from exposure to raw or undercooked meat, poultry, milk, and eggs.
