After the White House issued its recent statements regarding action on antibiotic-resistant Salmonella, the Center for Science in the Public Interest (CSPI) is asking USDA to declare four antibiotic-resistant strains of the pathogen to be classified as adulterants under federal law.

CSPI filed a petition with the agency that states USDA is obligated to keep those strains out of the food supply. The government agency denied a 2011 CSPI petition in July that asked it to declare antibiotic-resistant Salmonella strains that caused illnesses as adulterants in ground meat and poultry.
