Prevalence of <i>Eschericia coli</i> 0157:H7 in fresh and roasted beef in Kano City, Nigeria

Abstract

The prevalence of Enterohemorrhagic Escherichia coli 0157:H7 in 300 fresh beef and 150 roasted beef samples from Kano city Nigeria was determined, by direct plating on Sorbitol MacConkey agar (CT-SMAC) supplemented with Cefexime 50µg/L and Potassium tellurite 25mg/L and resuscitation on Trypticase Soy Broth (TSB) at 25 0 C for two hours for roasted beef samples. Presumptive colonies were confirmed by using E. coli 0157:H7 latex agglutination test kit. Prevalence rate of 53% was obtained in fresh beef and 25.3% in roasted beef. Consumption of inadequately cooked beef poses a serious risk of infection. The study therefore stressed the need for health authorities to educate and put in place efficient surveillance strategies for detection and control of possible outbreaks of E. coli O157:H7 in the society.

Occurrence and Antibiogram of Escherichia coli O157 : H7 in Raw Beef and Hygienic Practices in Abattoir and Retailer Shops in Ambo Town, Ethiopia

“…However, the present finding is higher than some other reports from Ethiopia, such as 1.3% in Addis Ababa [ 25 ], 2.7% in Haramaya University [ 24 ], and 6.7% in Mekele [ 35 ], and also from other countries in the world, such as 3.76% in Botswana [ 36 ], 1% in Ireland, 0.3% in the Czech Republic, and 0.3% in the Netherlands [ 37 ]. On the other hand, other scholars reported much higher results than the present findings: 60% from street meat sellers in Mekele town and 19.8% and 53% in Nigeria [ 38 ]. The overall variations in the prevalence of E. coli O157 : H7 might be due to the difference in sample size, sampling techniques, laboratory methodologies, study areas, time, and hygienic conditions employed [ 26 , 39 ].…”

Escherichia coli O157:H7 in Raw Meat in Addis Ababa, Ethiopia: Prevalence at an Abattoir and Retailers and Antimicrobial Susceptibility

“…The difference in the overall prevalence observed among the three types of meat samples in present study is high (13.3%) in beef, but relatively similar between sheep meat (9.4%) and goat meat (7.8%). In contrast, the prevalence of E. coli O157:H7 in beef in this study was higher than the 8.8% prevalence reported by Abong (2008) in South Africa and Hajian et al (2011) in Iran; and lower than 53% prevalence reported by Dahiru et al (2008) in fresh beef meat in Nigeria.…”

Risk Analysis and Antibiogram Spectrum of &lt;i&gt;Escherichia coli&lt;/i&gt; O157: H7 Serotype from Children Stool and Raw Bovine Meat in Households Across Cross River State, Nigeria

“…The overall prevalence of E. coli O157:H7 from bovine meat in the present study (21.11%) was higher than the 4.2% reported by [18] and 10.2% by [19] in various areas in Ethiopia. In contrast, the results obtained in this study was higher than the 8.8% prevalence reported by [20] in South Africa and [21] in Iran; and lower than 53% prevalence as reported by [22] in fresh beef meat in Nigeria. The presence of E. coli O157: H7 in meat might be due to contamination either from gastrointestinal content and/or skin [23].…”
