“…Public health (zoonotic) risk associated with the respondents' awareness and practices of bTB found in this study had agreed with the report of Cadmus and Adesokan [ 8 ] who reported an economic loss of N13, 871,014/annum with associated public health implications due to tuberculosis (7.95%) as major reasons for condemnations in some abattoirs in Western Nigeria. This also agreed with the report of Cadmus et al [ 21 ] and Bello et al [ 22 ], on management of slaughter houses in Northern Nigeria, who reported that none of the major abattoirs in Northern Nigeria met the minimum hygienic standard of operation as recommended by the Codex Alimentarius and they could not have supported the production of safe meat and meat products for human consumption.…”

Bovine tuberculosis (bTB) is a chronic infectious and contagious zoonotic disease of domestic animals, wild animals, and humans. It poses a public health threat and economic losses due to abattoir condemnation of infected carcasses during meat inspection of slaughtered animals. Bovine tuberculosis is widespread in Africa including Nigeria affecting both cattle and humans, particularly Northern Nigeria. A prospective survey was conducted from June to August 2013 in the three Zonal abattoirs of Bauchi State, Nigeria. A total of 150 structured close-ended questionnaires were administered to abattoir personnel to assess their level of awareness of bTB. This study was aimed at determining the level of public health awareness, attitude, and practices of abattoir workers of bTB in Bauchi State, Nigeria. There was a statistically significant association between respondents' awareness of bTB and their occupational status, age, and duration of exposure to cattle carcasses (P < 0.05); the odds of being aware of bTB were 9.4, 7.3, and 2.1, respectively. In conclusion, these demonstrate the urgent need for public health authorities to intervene in bTB control. The risk of bTB transmission as indicated by the personnel's practices and awareness levels in Bauchi State could be prevented through the use of protective clothing (PPEs).

“…The preponderance of the Staphylococcus contaminants in beef widely consumed in Nigeria [ 30 ] is disheartening in view of the toxigenic and antimicrobial resistance profiles of the contaminants. High rate of contamination of beef could be attributed to unwholesome slaughter or beef processing practices in some slaughterhouses in the study area [ 31 , 32 ]. The practice of flaying or evisceration of cattle carcass on bare floor or immersion of processed meat in water of unproven microbial quality, to make it appear bigger, predisposes meat to Staphylococcus contamination [ 33 ].…”

Aim:An epidemiological surveillance for Staphylococci contamination of ready-to-eat (RTE) meats from Enugu State, Nigeria, was carried out to determine the prevalence, species distribution, toxigenic potential and antimicrobial susceptibility profile of the organisms and hence the microbiological and toxicological safety of the meats.Materials and Methods:Isolation and phenotypic Staphylococcus detection were done according to standard microbiological methods. Phenotypic resistance to 17 commonly used antimicrobial agents was determined by disc diffusion method. Molecular characterization of the isolates to species level and detection of selected toxigenic and antimicrobial-resistance genes were done by PCR methods.Results:Twenty-four (9.4%) of the 255 meat samples investigated were contaminated with Staphylococcus species. Twenty-four Staphylococcus isolates belonging to six species of coagulase-negative Staphylococcus (CoNS) were identified. Four (16.7%) isolates harbored genes coding for exfoliative toxin-A. Ten (41.7%) isolates were multidrug resistant, while mecA, tetK, mphC, ermT and ermC were the antimicrobial-resistance genes detected in the isolates. Meat samples sourced from motor parks (16.7%) and open markets (8.5%) were the most contaminated.Conclusion:9.4% of RTE meats sampled were contaminated with toxigenic and multidrug resistance CoNS. Beef was the most contaminated RTE meat type and harbored all the toxigenic and most of the antibiotic-resistant genes detected. Meat samples from motor parks had the highest staphylococcal contamination (16.7%), while those from mechanic village had the least (2.4%). Majority (79.2%) of the isolates were not susceptible to fusidic acid but none exhibited antimicrobial-resistance to chloramphenicol, ciprofloxacin, linezolid or teicoplanin. Food safety authorities in the study area should work proactively to massively improve the hygienic practices of meat vendors; in order to limit staphylococcal contamination of RTE meats and the associated public health problems.

“…In developing countries, animals are commonly slaughtered and dressed under unhygienic conditions and this further compromises the microbiological quality and safety of the meat obtained from the animals [6,7]. The presence of Escherichia coli O157:H7 in animal faeces provides the potential for these organisms to enter the food chain via faecal contamination of milk, contamination of meat with intestinal contents during slaughter or contamination of fruit and vegetables by contact with contaminated manure.…”

Background: Raw meat is one of commonly consumed traditional diets in Ethiopia. However, unhygienic processing and distribution practices were risky for contaminations of meat leads to human infection. This study was conducted to assess the presence of multi-drug resistant E. coli and E. coli O157:H7 in meats, ceacal content, and swabs samples of different contact surfaces at abattoir and butcher shops in Jimma town, Southwest Ethiopia. Methodology: A cross-sectional descriptive study was conducted from April to July, 2018. The isolation and identification processes passed through enrichment of samples with modified tryptone soy broth (mTSB), streaked onto MacConkey agar and Cefixime- tellurite sorbitol MacConkey agar, biochemical testing (indole and TSI), followed by latex agglutination test. Results: Out of 505 samples, 102(20.2%) and 27(5.4%) were positive for E. coli and E. coli O157:H7, respectively. Of these, 55(19.3%) and 47 (21.4%) of E. coli and 17 (6.0%) and 10 (4.5%) of E. coli O157:H7 were isolated from the abattoir and butcher shop samples, respectively. A significant difference in the occurrences was observed among sample sources. Antimicrobials susceptibility test result showed that, 92.2% to 96.1% of E. coli and 85.5% to 96.3% of E. coli O157:H7 were susceptible to third generation cephalosporin, ciprofloxacin, gentamycin, kanamycin, streptomycin and chloramphenicol. About 91.2% and 97.1% of E. coli and 88.9 % and 92.6% of E. coli 0157:H7 were resistant to ampicillin and erythromycin, respectively. A total of 98 (76.0%) E. coli and E. coli O157:H7 isolates were resistant to two or more classes of antibiotics. All abattoir and butcher shops workers were not have any formal education and training certificate on food safety and unhygienic practice were also observed.Conclusion: The presence of E. coli and E. coli O157:H7 including multi-drugs resistant isolates in raw meat highlights how the current meat processing and distribution practice was unhygienic. Therefore, strategies in the prevention and control of food borne infections that could be caused by multi-drug resistant strains will depends much on hygienic processing and distribution practices of meat.
