UK food industry watchdog, the Food Standards Agency (FSA), is set to review the Over Thirty Month (OTM) rule implemented to control the spread of BSE, which prohibits the sale of meat for human consumption from cattle aged over 30 months at slaughter. The rule was introduced in 1996 and has had a major impact on reducing the risk to public health by significantly limiting the number of infected animals which might otherwise have entered the food chain.
