RESUMEN
ABSTRACT Introduction Clostridium difficile is an important cause of diarrhoea, particularly in patients receiving antibiotic therapy. Recent studies have shown that a substantial proportion of C. difficile infections are acquired in the community, as a zoonotic disease. Brazil is a large exporter of meat and so far no study has evaluated meat contamination with C. difficile spores. Methods Here we analysed 80 retail meat products purchased from local supermarkets in a Brazilian metropolis (Porto Alegre, Southern Brazil). Samples from these products were grown in anaerobic conditions, and tested with a real time polymerase chain reaction test. Results Contamination with C. difficile spores was not found in the study. Bacteria isolated from meat included Streptococcus gallolyticus, Lactobacillus plantarum, Enterococcus gallinarum and Pediococcus acidilactici. Discussion Close vigilance is required in order to guarantee the quality of Brazilian retail meat in the long term.
