A survey of abattoir data in northern Nigeria.

A survey of the abattoirs in 10 selected towne in Nigeria showed that about 41.9 per cent of whole carcasses condemned between 1975 and 1977 were due to tuberculosis and 22.2 per cent to beef cysticercosis. Seventy per cent of organ condemnations, mainly of livers, were due to fascioliasis. Other major causes of organ condemnations were hydatid cysts, tuberculosis and pneumonia of various causes. An estimated 500 tonnes of meat valued at about 1.25 million Naira (US $1.8 million) are condemned each year throughout Nigeria. The use of abattoirs as monitoring stations in national animal disease eradication programmes is highlighted.
