Researchers at the U.S. Centers for Disease Control (CDC) believe that cases of resistant salmonella occurred in about two of every 100,000 cases annually between 2004 and 2012, according to the Center for Infectious Disease Research and Policy (CIDRAP) at the University of Minnesota.

The CDC report cited clinically significant resistance being linked to four specific salmonella serotypes: Enteritidis, Newport, Typhimurium, and Heidelberg with what is considered nontyphoidal salmonella causing an estimated 1.2 million foodborne illness cases each year. Although most people with salmonella infections recover within a week and do not require antibiotics, about 450 people die from salmonella infection annually.

The new figures are based on data from the U.S. Census Bureau and two surveillance systems the CDC uses to track both salmonella and antibiotic-resistant salmonella. The four serotypes account for only half of the culture-confirmed salmonella infections, but accounted for 73 percent of the salmonella infections that involved clinically important resistance.

The CDC added that for every culture-confirmed case of salmonella infection, there may be as many as 29 undetected cases among the U.S. population, placing the annual incidence estimate at 180,000 cases.
