Occurrence of Salmonella in ruminants and camel meat in Maiduguri, Nigeria and their antibiotic resistant pattern

Abstract

Objective: This study was conducted to determine the occurrence of Salmonella in various meat products (beef from cattle, chevon from goats, mutton from sheep and jaziir from camel), by screening the various selling points which includes; meat retailers in abattoir, markets and shops in Maiduguri and its environs. Materials and methods: A total of 120 samples of fresh meat from cattle, sheep, goats and camels sampled from ten meat retailers in abattoir, markets and shops in the Maiduguri metropolis, using simple random sampling technique. All samples were processed and examined according to standard bacteriological protocols. Results: Percentage occurrence of Salmonella species had the highest value of 15 (50.1%) from the market, found in sheep, while the lowest occurrence of Salmonella species was associated with 3(10.0%) in goats sampled from shop meat.. Antibiotic susceptibility pattern of Salmonella species from cattle meat revealed high resistant to Erythromycin (52%). In sheep, the higher percentage of resistance occurred against Ampicillin (33.3%) and less resistant to Amoxicillin (4%) was obtained. The isolates from camel meat recorded 25% resistant against Ampicillin, Gentamycin and 12.5% to Streptomycin. A total of 28.4% of the isolates were resistant to Ampicillin, Gentamycin and 23.1% to Ofloxacin. Conclusion:The study has shown that Salmonella species are present in fresh meat sold in abattoir, retail markets and shops. We recommend strict hygienic measures in places where fresh meat are sold in Maiduguri metropolis, Nigeria to ensure consumers right to have safe food.

Microbiological Quality Assessment of Marketed Broiler Meat in Different Markets of Dhaka City

“…was Gram negative, very short plump rod arranged as single or paired and those properties of Salmonella spp. were supported by other authors (Musa et al, (2017); Kamal et al, (2018). Isolated Salmonella spp.…”

“…were able to ferment dextrose, maltose and mannitol with the production of both acid and gas but did not ferment lactose and sucrose and those characteristics of Salmonella spp. were satisfied the statement of (Han et al, 2011; Musa et al, (2017).…”

Prevalence, genetic characterization, and antimicrobial resistance of Salmonella isolated from meat goats in the Northeastern region of Thailand

“…Teklu and Negussie (2011) reported a prevalence of 11.7% for Salmonella in goats at an export abattoir in Ethiopia, and Ferede et al (2015) reported a prevalence of 17.7% in apparently healthy goats at Dire Dawa municipal abattoir, Eastern Ethiopia. Similar prevalence of Salmonella in goats and goat meat was reported in Nigeria, where prevalence of Salmonella infections in goats was found at 17.6% (Chandra et al, 2006); 10% of goat meat sampled from retail shops in Maiduguri were shown to contain Salmonella (Musa et al, 2017). In the Asian country of Bangladesh, the prevalence of Salmonella associated with goats was reported at 12.76% (Saha et al, 2013).…”

Prevalence, Antimicrobial Resistance and Risk Factors of Zoonotic Foodborne Pathogens Isolated from Camel Meat

“…From the previous investigations concerned camel meat, Salmonella was mentioned in agreement with the current obtained results as: 10% in Menofia governorate, Egypt (Edris et al, 2013), and 8% in Behera governorate, Egypt (Nossair et al, 2016). Higher prevalence rates were detected as: 16.2% in Ethiopia (Molla et al, 2003), and 20% in Nigeria (Musa et al, 2017) whereas Sevilla-Navarro et al ( 2021) reported a lower prevalence rate of 5.5% in Iraq. Regarding S. aureus, the obtained results were in accordance with Al-Thani and Al-Ali ( 2012) who reported a prevalence rate of 23.8% in Qatar.…”

“…showed resistance to all the used antibiotic discs (Amoxicillinclavulanic, Doxycycline, Ampicillin, Cefotaxime, Ciprofloxacin, Ceptaxime, Imipenem, Tetracycline, Streptomycin, and Nalidixic acid) whereas the Gram positive S. aureus showed resistance against (Amoxicillin-clavulanic, Ampicillin, and Ceptaxime). From the previously published data upon the antibiotic resistance of pathogens isolated from camel meat, Musa et al (2017) represented Salmonella spp. in Nigeria were susceptible to the antibiotics since the pathogen showed resistance percentages of 25% against Ampicillin, 12.5% against Streptomycin, and 0% against both Ciprofloxacin and Tetracycline.…”
