The United Nations Food and Agriculture Organization is urging farmers to be on guard against transboundary animal diseases. Officials warn that ticks, lice and other pests can spread quickly from one country to the next. Experts from across Africa say trans-border diseases kill between 10 and 20 percent of the continent’s animals every year. The experts gathered in Cameroon last month to discuss the problem. They suggested large vaccination and anti-pest programs to stop the spread of the diseases. Dr. Taiga is Cameroon’s livestock minister. He says pests like nose bot flies and wool maggots are harming animals in some areas of his country. Dr. Taiga says all animals in an area must be killed if one animal is affected because the diseases are contagious. They spread quickly from animal to animal. He says the FAO and the World Organization for Animal Health are working together to destroy the diseases. Dr. Sebastien Mongomo is an animal pest expert from Equatorial Guinea. He told the conference that diseases caused by pests have killed at least 10 percent of the sheep and goats in his country this year. Dr. Mongomo says it is difficult to control the movement of animals across country borders. Dr. Felix Njemi is an animal health officer at the FAO. He says the large number of animal deaths is worsening the food crisis in Africa, especially in countries south of the Sahara Desert. He says the diseases can impact food security.
