No association has otherwise been demonstrated with any occupational group. All existing guidance is currently being reviewed and will be revised where necessary. The principles of the control measures previously recommended remain valid, for example the need for high standards of personal and occupational hygiene. Since 1988, all definite and suspected cases of BSE in cattle have been slaughtered and incinerated. Meat and bone meal derived from rendering non SBM from cattle less than 30 months old and for human consumption can be safely disposed of by landfill as can incinerated bovine waste.
Liquid waste poses a negligible risk when disposed of by land spread.
The Government has as an extreme precautionary measure prohibited the sale of beef for human consumption from cattle over the age of 30 months. No BSE infectivity has ever been found in milk from clinically affected cows. SEAC is satisfied that milk and dairy products can he safely consumed. This conclusion has been endorsed by the World Health Organisation. This advice also applies to infants, children of school age and vulnerable groups such as the immunosuppressed, patients in hospital and pregnant women.
