Risk management measures to reduce exotic disease risk of feeding processed catering waste (etc) to non-ruminants - SE4406

The feeding of food waste to pigs and other livestock is a practice carried out in many countries under various processing conditions. The UK has prohibited the feeding of catering waste and former foods associated with animal by-products from being fed to livestock due to the risk of spreading disease. Recent research commissioned by Defra found that more food waste could be used safely if properly segregated and if changes in legislation were made (e.g. former foodstuffs containing poultry-sourced ABP could be fed to pigs). However, further research was required to explore whether it would be feasible to put in place control measures that would ensure that the additional risk of an outbreak of exotic notifiable disease - that might arise from the feeding of processed catering/food waste to non-ruminants - is no greater than negligible levels (as defined internationally).

The proposed research will assess potential risk management measures to reduce the exotic disease risk of feeding processed catering waste and former foodstuffs no longer intended for human consumption containing products of animal origin. The OIE framework for risk assessment of release, exposure and consequence assessment, will be used. It is likely with some knowledge of the data sources available that the risk assessment will be semi-quantitative, with quantitative estimates made where numerical data are available. A review of the relavant literature will be conducted to parameterise the risk assessment. It is likely that there may be gaps in knowledge for some aspects in which case expert opinion will be sought. The resulting risk assessment, data, assumptions, and results will be provided within a technical report and subject to review by Defra and other scientific bodies if required.
1. Identification and agreement on the risk question and the hazards to be included in the assessment in consultation with Defra.
2. Release Assessment. The release assessment will provide a summary of the ways in which catering waste and former foodstuffs no longer intended for human consumption may become contaminated with exotic animal diseases. The initial loading of the pathogen in the animal product will be evaluated by prioritised hazard.
3. Exposure Assessment to assess the fate of the pathogen post processing under difference methods and develop the risk pathways from designation as food waste to ingestion by livestock as animal feed.
4. Investigation of dose-response relationship for prioritised hazards.
