oa Central African Journal of Medicine - Rift valley fever in abattoir workers

Volume 26, Issue 6
  • ISSN : 0008-9176



Antibody titres indicative of Rift Valley Fever (RVF) infection were found in the sera of 32 out of 365 (9%) workers at the Sinoia abattoir who were tested following the 1978 epizootic. A significantly higher rate of infection was found in workers who had regular contact with fresh carcasses and organs compared with that in workers with no apparent contact at all or in contact with cold or frozen tissue of 24 hours old or more. The highest incidence of infection occurred in 9 out of 16 workers (56%) in the byproducts section of the abattoir where diseased carcasses are processed. This suggests that RVF-infected carcasses are generally condemned as unfit for human consumption. Control measures include vaccination of abattoir staff, increased vigilance at abattoirs and improved vaccination cover of livestock in enzootic areas.
