Super bug bacteria in meat and poultry, study says - SmartPlanet

Meat and poultry inspectors usually look for many types of multi-drug-resistant bacteria, but staph is often times overlooked. The bacteria can cause skin infections and can lead to more serious illnesses such as pneumonia and sepsis.

Here’s a summary of what the study, published in the journal Clinical Infectious Diseases, found:

  • half of the meat sold in grocery stores are contaminated with S. aureus
  • one in four samples were resistant to at least three classes of antibiotics
  • methicillin-resistant staph was found in three of the samples
  • the staph are resistant to up to nine different antibioitics, making it hard to treat

However, The New York Times reports that “federal health officials estimate that staph accounts for less than 3 percent of all food-borne illnesses. In a statement Friday, the American Meat Institute said the study was misleading.” Businessweek reports staph infections occur only three percent of the time and are not nearly as common as other foodborne illnesses like salmonella and E. coli.

Multidrug-Resistant Staphylococcus aureus in US Meat and Poultry

Abstract

We characterized the prevalence, antibiotic susceptibility profiles, and genotypes of Staphylococcus aureus among US meat and poultry samples (n = 136). S. aureus contaminated 47% of samples, and multidrug resistance was common among isolates (52%). S. aureus genotypes and resistance profiles differed significantly among sample types, suggesting food animal–specific contamination.

Antimicrobials are used extensively in food animal production, where they are often applied subtherapeutically for growth promotion and routine disease prevention [1]. Surveys conducted by the National Antimicrobial Resistance Monitoring System (NARMS) indicate that retail meat and poultry products are frequently contaminated with multidrug-resistant Campylobacter species, Salmonella species, Enterococcus species, and Escherichia coli [2]; but little is known about the prevalence of other antibiotic-resistant pathogens in the US food supply.
