The microbiological requirements for enhanced treated sludge in the Safe Sludge Matrix are reviewed and compared with those for foods, which are much less stringent. Quantitative microbial risk analysis shows that the risks to human health from disease transmission through sewage sludge to grazing animals or food crops are very low, indicating that the strict requirements of the Safe Sludge Matrix are not really justifiable.
