A federal-state partnership that monitors for foodborne illnesses quietly scaled back its operations nearly two months ago. As of July 1, the Foodborne Diseases Active Surveillance Network (FoodNet) program has reduced surveillance to just two pathogens: salmonella and Shiga toxin-producing E. coli (STEC), a spokesperson for the Centers for Disease Control and Prevention told NBC News. Before July, the program had been tracking infections caused by six additional pathogens: campylobacter, cyclospora, listeria, shigella, vibrio and Yersinia. Some of them can lead to severe or life-threatening illnesses, particularly for newborns and people who are pregnant or have weakened immune systems.
