ABSTRACT
Wanzala W,
Onyango-Abuje JA, Kang'ethe
EK, Zessin KH, Kyule NM,
Baumann MPO, Ochanda H, Harrison LJS., Analysis of
post-mortem diagnosis of bovine cysticercosis in
Kenyan cattle, Onl J Vet Res., 7:1-9, 2003. A total of 55 cattle divided into two groups of
experimentally (n =30) and naturally (n = 25) infected animals
were used to study the reliability of meat inspection methods in Kenya.
Total dissection method was used as a gold standard to indicate the absence or
presence of bovine cysticercosis infection in cattle.
The level of agreement between the two methods was, on average, lower in naturally
infected animals than in artificially infected calves. This was because in
natural infections, there were more light infections than in experimental
infections and these could not be detected by meat inspection method. The
results further confirm that in spite of the time and effort taken by meat
inspectors in looking for cysticerci at predilection
sites, this method is very insensitive. It was therefore recommended that more
parts of the carcass not currently inspected according to the Kenya Meat
Control Act – 1977, for bovine cysticercosis such as
hind legs, ribs, lungs and liver, need to be considered as possible and equally
important predilection sites and larger areas of these predilection sites
should be examined. However, other better sensitive ante-mortem diagnostic
methods should be developed to assist in the integrated management of the
infection.
