Slaughterhouse video prompts unprecedented beef recall

This undercover video of sick and crippled cows being brought to slaughter in an abattoir in southern California has prompted the largest recall of beef in US history, (writes Will Pavia).

The US Department of Agriculture yesterday ordered that 143 million lb of beef from the slaughterhouse be recalled. Officials estimate that some 37 million lbs of the recalled meat had been heading to schools across America though they fear that most of it will have already been eaten.
