§ Mr. HindTo ask the Minister of Agriculture, Fisheries and Food what changes have been made in the temperature levels defined as appropriate for the heat treatment of animal waste since 1980; and if he will make a statement.
§ Mr. MacleanThe Government have strict controls which apply to animal protein processors' handling of animal waste, principally to minimise the risk of salmonella contamination, but it has never laid down specific heat treatment requirements.
Commercial technological developments led to a move away from batch processing to continuous rendering. Both batch and continuous systems operate at a range of temperatures; batch between 100 and 150 deg. C, and continuous between 100 and 145 deg. C.
