ARS scientists in Beltsville, Md., and Athens, Ga.—and their co-investigators—are analyzing dairy manure samples, bird droppings and water, for instance, from test farms in New York, Pennsylvania and Vermont to check for such pathogens as Salmonella, E. coli, Listeria and Campylobacter.An example: Samples from one farm showed that although 45 percent of the cows tested positive for Salmonella, milk from the animals was free of detectable levels of the microbe
