Centers for Disease control and prevention (CDC) and the U.S. Food and Drug Administration (FDA) have announced food safety alert regarding the outbreak of Salmonella Newport infections linked to onions in various states in America.
Salmonella enterica serotype Newport isolates resistant to at least nine antimicrobials (including extended-spectrum cephalosporins), known as serotype Newport MDR-AmpC isolates, have been rapidly emerging as pathogens in both animals and humans throughout the United States.

In addition to the resistance to five drugs found in Salmonella serotype Typhimurium DT104, this Salmonella serotype Newport, called serotype Newport MDR-AmpC, is also resistant to amoxicillin-clavulanic acid, cephalothin, cefoxitin, and ceftiofur and exhibits decreased susceptibility to ceftriaxone (MIC ≥ 16 μg/ml). Some serotype Newport MDR-AmpC strains have shown resistance to gentamicin, kanamycin, and trimethoprim-sulfamethoxazole. A multistate outbreak of serotype Newport MDR-AmpC infections was reported by the Centers for Disease Control and Prevention (CDC), and raw or undercooked ground beef was implicated as the vehicle of transmission.
