Antibiotic-Resistant Bacteria in Raw Meat from Retail Markets

Abstract

Raw meat samples from retail markets were examined for bacteria resistant to chloramphenicol and neomycin sulfate. Total numbers of bacteria ranged from 17,000 to 30,000,000 per gram and resistant bacteria from < 100 to 450,000 per gram. Twelve isolates resistant to both antibiotics were identified as either Pseudomonas aeruginosa, Pseudomonas putida. or Pseudomonas fluorescens.
