Meat-eating is on the rise around the globe, a trend that could raise the risk of animal disease spread across borders, the Food and Agriculture Organization of the United Nations (FAO) said this week in a document circulated at a meeting on meat and dairy products. Worldwide meat consumption is expected to grow by 2 percent each year until 2015 — the result of population increases, rising incomes, and the movement of people from rural areas to cities. “However, increased volume of trade and improvements in transportation, infrastructure and technology hold potential risks of spreading of animal diseases rapidly worldwide,” FAO warned.
