Today is World Food Safety Day, and the U.S. Department of Agriculture’s Agricultural Research Service (ARS) has launched a sweeping new initiative known as the Salmonella Grand Challenge. The project brings together an elite group of ARS, university and food industry scientists from different specialties to fight Salmonella, a foodborne pathogen that sickens over a million Americans each year, sometimes fatally. The challenge complements the work being done by the Food Safety and Inspection Service to develop a more effective strategy to reduce human Salmonella illness linked to poultry.
