Antibiotic-Free poultry half as likely to be contaminated with MDR-Salmonella

IDWeek 2019 5 October, 2019

Meat from conventionally raised poultry was twice as likely to contain multidrug-resistant Salmonella as poultry labeled antibiotic-free or organic, according to a first-of-its-kind study being presented at IDWeek 2019. A related study of a variety of meat purchased from randomly selected stores found nearly one-third of Salmonella in contaminated samples was resistant to three or more antibiotics and more than one in six were resistant to five or more antibiotics. Severe Salmonella infection requires treatment with antibiotics, which is especially challenging when the bug is highly resistant to drugs. In the study, researchers reviewed data from chicken and turkey randomly purchased in Pennsylvania between 2008-2017 and found 280 of the 2,733 (10.2%) samples of conventionally raised poultry were contaminated with non-typhoidal Salmonella compared to 40 of the 748 (5.3%) poultry samples labeled antibiotic-free. Further, they determined that 154 of 280 (55%) Salmonella cultures from conventionally raised poultry were resistant to three of more antibiotics compared to 11 of 40 (28%) Salmonella cultures from poultry raised without antibiotics.
