By Kurt Kleiner COWS are no longer cannibals, but some are turning into vampires. Some farmers in the US are giving calves a processed food supplement that contains cows’ blood. The practice has not caught on in Britain. But even the strict British prohibition on feeding animal protein to cows makes an exception for blood and milk, so it would not be illegal. American pig farmers have fed their animals blood for some time, but its use by cattle farmers has only begun to take off in the past year, says Michael Hansen of the Consumer Policy Institute in Yonkers, New York, which opposes the practice. The feed is given to veal and dairy calves to promote growth. Blood is heated to 200 °C then forced through a sprayer. Dried droplets are processed into feed. Jim Quigley, a nutrition manager at American Protein, a company in Ames, Iowa, that makes the supplement, says the blood is only taken from cows which have been certified as healthy by the US Department of Agriculture. There is no evidence that BSE is transmitted by eating blood. “We consider blood a safe product for cattle, so long as the cattle have been killed for human consumption,” says Ray Bradley, a veterinary pathologist based in Surrey who serves on the British government’s Spongiform Encephalopathy Advisory Committee. But with feelings running high in Britain after the launch of a BSE public inquiry, consumer groups are anxious that the practice should not cross the Atlantic. “Given the origin of BSE from feeding meat and bone meal to cattle, we’re obviously concerned,” says Rory Hegerty,
