Antibiotic-Resistant Bacteria Found in Produce, Dairy Products Some bacteria even resistant to colistin

Antibiotic-resistant bacteria were found in fresh produce and dairy products throughout California grocery stores, researchers found. Samples from organic and conventional produce were the most resistant to cefotaxime, an antibiotic that treats a variety of bacterial infections. Moreover, numerous samples were positive for bacteria resistant to colistin, a "last resort" antibiotic, reported Bryan Sanchez, of California State University Northridge, and colleagues. The authors described their study as "preliminary surveillance." They purchased organic and conventional produce and dairy products at grocery stores throughout the San Fernando Valley. They defined antibiotic concentrations as the minimal concentration to inhibit particular strains of both Escherichia coli and Staphylococcus aureus. Researchers then measured antibiotic resistance against eight types of antibiotics: Ciprofloxacin Tetracycline Erythromycin Chloramphenicol Gentamicin Ampicillin Cefotaxime Colistin https://www.medpagetoday.com/MeetingCoverage/ASMMicrobe/65821?xid=nl_mpt_DHE_2017-06-07&eun=g721819d0r&pos=0
