load and antibiotic susceptibility pattern of microorganisms in muscle foods sold in akure, southwest nigeria

Background: muscle foods, notably red meat, poultry meat, and fish are the first choice of animal source food with adequate protein for human. the present study was undertaken to analyze the load and antibiotic susceptibility pattern of microorganisms in muscle foods sold in akure, southwest nigeria.methods: hundred muscle food samples, including meat and fish were collected from different locations (ae) of akure, nigeria and examined microbiologically using cultural techniques, biochemical tests, and analytical profile index. antibiotic susceptibility patterns were also determined in isolated microorganisms from muscle foods against different antibiotics. data were analyzed using spss software version 17.0.results: the highest (p<0.05) total viable bacterial count (8.3 ×10^6 cfu/g) were obtained from pork, including with 6.0 ×10^5 cfu/g for staphylococcus and 5.8 ×10^5 cfu/g for salmonellashigella. mackerel collected from location d (kings market) had the highest (p<0.05) bacterial count of 9.97 ×10^5 cfu/g, followed by 8.57 ×10^5 cfu/g, and 7.03 ×10^5 cfu/g in locations c and e, respectively. low fungal counts were recorded ranged from 1.0 ×102 to 1.30 ×102 spore forming unit/g. the highest (p<0.05) occurrence of 26.50% was observed for escherichia coli. the isolated microorganisms displayed varying degree of resistance (33.3 to 100%) to commonly used antibiotics.conclusion: the microorganisms found in muscle foods from akure, nigeria could be considered as result of poor hygiene of the retailers or handlers. also, presence of the multidrug resistant bacteria in muscle foods distributed in this region could pose a serious risk factor to public health.
