Many Vibrio species are pathogenic to humans and have been implicated in food-borne disease. They are naturally found in the estuarine and marine environment. The aim of this study is to study the distribution and antibiotics susceptibility profiles of Vibrio species recovered from two selected abattoirs in Akoko Southwest. A total of fifteen (15) samples consisting of Slab swabs (n = 4), Meat (n = 4), Effluent (n = 4), and Knife (n = 3) were collected from Abattoirs in Akungba and Iwaro-Oka Akoko. Bacteriological investigation was carried out in accordance with the microbiological standard method by serially diluted each sample in test tubes filled with 9ml of enrichment medium (Alkaline Peptone Water) and were isolated through the use of TCBS agar which is one of the recommended media for the selective isolation of Vibrio species. The overall proportion of Vibrio positive isolates was 86.67% in all samples, of which 100% were from effluent and meat, 75% slab and 66.67% knife. It was observed that more Vibrio spp. were isolated from the meat and effluent discharged than from other sources. The bacteria (Vibrio species) isolated were subjected to various biochemical tests and were also subjected to antimicrobial susceptibility tests. The isolates showed resistance to multiple antibiotics, and the susceptibility pattern of the isolates to different antibiotics was tested and interpreted using the disk diffusion method (Kirby-Bauer) described by the Clinical and Laboratory Standards Institute. It was observed that the organisms were susceptible to Imipenem, Nitrofurantoin, Ciprofloxacin, Azithromycin and Augumentin. Moreso, of the identified Vibrio species large percentage showed resistance to Tetracycline and Ampicillin. This study clearly indicated and concluded that the meat and the effluents discharged from these abattoirs to the environment are reservoir for Vibrio species as well as antibiotics resistance genes. The high distribution of resistant vibrios in these abattoirs shows potential public health hazards. Therefore, there is an urgent need to establish a sanitation and hygienic intervention majorly focused on limiting the rate of contamination of the slaughtered animal in causing human illness when in contact with, and also to adopt a strategies that are effective in eliminating antibiotics resistant Vibrios species.
