Poultry producers around the world are on high alert as avian influenza spreads through flocks.
New outbreaks were reported today in Senegal, in North Africa. The disease killed 60,000 birds on a commercial poultry farm. Producers are culling another 40,000 birds.
Another case in Lithuania killed a small backyard flock. Officials have quarantined the area.
More widespread outbreaks have slashed sales in other parts of the world. In India, broiler chicken prices fell by a third, after the virus was found in six states. In the past week, retail prices dropped about 30 percent. In France, duck farmers will cull more birds and the quarantine zones are expanded.
It has triggered a trade ban from China, one of its biggest customers.
