PREVALENCE AND MOLECULAR CHARACTERIZATION OF ROTAVIRUS IN MEAT CUTS, AND MEAT HANDLERS IN SELECTED ABATTOIRS IN NAIROBI, KENYA

In Kenya, food screening exercises mostly applies to bacterial and parasitic agents, with enteric viral detection neglected. This study aimed to determine the prevalence and molecular characterization of rotavirus in beef/pork cuts and beef/pork handlers in 4 selected abattoirs in Nairobi. Rotavirus was preferred because of its high prevalence rates and its ability to cause pathophysiologic infective gastroenteritis in humans. It has diverse strains characterized as P and G genotypes based on the VP7 and VP4 proteins, respectively. This cross-section study involved the collection of a total of 467, (165) beef/pork cuts and (302) handlers fecal samples. Collected samples wereprepared before rotavirus identification. Prepared meat and stool suspensions were subjected to direct RNA extraction and EIA detection respectively. All the stool suspensionsand RNA extracted meat suspensions subjected to EIA and Two step RT-PCR were all non-reactive respectively. Therefore, there was no VP4 and VP7 genotyping for characterizationpurposes on confirmed primary PCR products. Eppicollect5 was also used to collect and store the descriptive data of study participants, and the analysis conducted using Power BI statistical software application. The studys findings, indicating no human rotaviral infections in meat cuts, enhance public health by reassuring consumers, guiding regulatory policies, emphasizing the need for ongoing surveillance, directing resources to pressing concerns, supporting safe food handling campaigns, establishing baseline data for future assessments, and encouraging best practices in both formal and informal markets.
