Review of successes and failures of contagious bovine pleuropneumonia control strategies in Tanzania.

Contagious bovine pleuropneumonia (CBPP) was first introduced in Tanzania in 1916 and was eradicated in 1964. The disease re-emerged in the country in 1990 and since then it has spread widely, threatening the entire national cattle herd. Because of lack of a clear disease-control policy, uncontrolled cattle movements, lack of public awareness and commitment, ineffective legislation, attempts to control and eradicate the disease for the last 10 years have failed. We reviewed the methods that were used to control CBPP in Tanzania during the 1916-1964 and 1990 episodes.
