Drug Resistance in One Salmonella Strain Grows; Others Remain Low

Findings from the National Antimicrobial Resistance Monitoring System (NARMS) has found that overall drug resistance in Salmonella bacteria is low, except for one serotype. NARMS is a partnership between the CDC, the FDA, the USDA, and state and local health departments, that tracks antibiotic resistance in bacteria that cause human disease and are transmitted commonly through food. The report states that overall, antibiotic resistance in Salmonella bacteria is low, but multidrug resistance in one serotype is increasing. Multidrug resistance in Salmonella is 9.3%, a bit higher than the 2009-2013 average of 9%, but down from 11% in the 2004-2008 report. Resistance to one of the drugs used to treat severe Salmonella infections, ceftriaxone, dropped from 3% to 2%. But multidrug … [Read more...]

FDA Releases NARMS Report for Salmonella in Meat

The FDA has released the NARMS (National Antimicrobial Resistance Monitoring System) Retail Meat Interim Report with data from January 2014 through June 2015. This report focuses on Salmonella, including serotype distribution, prevalence by food source and state, selected resistance patterns, and a list of all the identified antimicrobial resistance genes. The "encouraging trends" in the report include finding that the prevalence of Salmonella in retail poultry is at its lowest level since testing began in 2002. In ground turkey, the prevalence of Salmonella has declined from a high of 19% in 2008 to 6% in 2014. In retail chicken during the same time period, it dropped from 15% to 9%. Salmonella resistance to ceftriaxone, a medically important antibiotic from chicken sources declined … [Read more...]

NARMS Now Interactive Tool Launched by CDC

NARMS Now, which is part of the National Strategy for Combating Antibiotic-Resistant Bacteria (CARB) and the President's Open Government Initiative has been released to the public. NARMS reports present aggregated data, but this new system is the entire collection of the government's enteric bacterial isolates collected over the past 18 years. The data includes information for Salmonella, Campylobacter, E. coli, and Enterococcus. It allows data sharing for those who want to download and analyze microbiological data. It will be incorporated into interactive displays to let readers visualize findings across sample sources. The new tool makes it quicker and easier to see how antibiotic resistance for four bacteria spread through food. Every year in the U.S., antibiotic-resistant … [Read more...]

FDA Releases NARMS Report on Antibiotic Resistance

The Food and Drug Administration (FDA) has released its 2012-2013 National Antimicrobial Resistance Monitoring System (NARMS) Integrated Report. The report focuses on major food born pathogens that are resistant to antibiotics important in human medicine, and on multidrug resistant pathogens. NARMS screens for non-typhoidal Salmonella, Campylobacter, E. coli, and Enterococcus. Salmonella and Campylobacter are the leading causes of bacterial food poisoning. The report reveals "mostly encouraging findings, with some areas of concern." About 80% of human Salmonella isolates are not resistant to any of the tested antibiotics. This number has not changed in the past 10 years. In addition, Salmonella multi-drug resistance has not changed, and the number of multi-drug resistant Salmonella … [Read more...]

Antibiotic Resistance Increasing for Some Pathogens, CDC Reports

Some types of Salmonella and other bacteria are increasing their resistance to antibiotics, according to a new report from the National Antimicrobial Resistance Monitoring System (NARMS) which tracks antibiotic resistance in humans, farm animals and deli meat. Each year, about 440,000 Americans develop antibiotic-resistant infections from foodborne germs. Created in 1996, NARMS is an interagency collaboration of the Centers for Disease Control and Prevention (CDC),¬†the U.S. Food and Drug Administration (FDA) and the U.S. Department of Agriculture (USDA). It tracks antibiotic resistance in six pathogens: non-typhoidal Salmonella,¬†typhoidal Salmonella, Shigella,¬†Campylobacter, E. coli O157, and Vibrio. The new report, based on information from 5,000 isolates gathered in 2013, … [Read more...]

FDA Releases 2012 NARMS Retail Meat Annual Report

The FDA has released two reports that measure antimicrobial resistance in certain bacteria isolated from raw meat and poultry. The data is collected through the National Antimicrobial Resistance Monitoring System (NARMS). The 2012 Retail Meat Report summarizes key findings in bacterial resistance related to raw chicken, ground turkey, ground beef, and pork chops collected at retail stores around the country. The 2013 Retail Meat Interim Report is also being released today, which focuses only on Salmonella. These reports detail antimicrobial resistance in Salmonella, Campylobacter, E. coli, and Enterococcus. The reports find that there was a decrease in third-generation cephalosporin resistance amount poultry meats in 2012 and 2013, although current cephalosporin resistance levels are … [Read more...]
