Surveillance Programme for Dioxins in Feeds
• 2008 – dioxins in pork meat
• Investigation: zinc oxide – need to monitor high risk ingredients
• 2009 – Programme starts
• 2013-2016 – Programme is established and consolidated for feed ingredients
• 200 samples/year

Epidemiologic study
• Epidemiology Unity used the data fromsamples, lots and lab results.
• Concluded that the investigation should be focused in the pork and poultry hydrolizedprotein and animal origin oil.
• Other product lots were sampled.
• Company was asked to improve the selfcontrolsystem (lot definition, storing of countersamples, etc.)
![Page 33: Presentación de PowerPoint€¦ · Subtitulo de la presentación en una línea Chilean experience with dioxin contamination in feed Alejandro Pozo Araya, MV Subdepartamento de Alimentos](https://reader033.fdocuments.in/reader033/viewer/2022060316/5f0c30bf7e708231d4342fae/html5/thumbnails/33.jpg)

Vegetable oil
• Product corresponds to a batch of a mix of soya and sunflower seed oils
• Imported and domestic oils and fats collectionestablishment
Manufacturer
• Export to Chile soya/sunfloweroil
Importer in Chile
• Sells to colectors
Collectors
• Store and supply to theindustry
![Page 42: Presentación de PowerPoint€¦ · Subtitulo de la presentación en una línea Chilean experience with dioxin contamination in feed Alejandro Pozo Araya, MV Subdepartamento de Alimentos](https://reader033.fdocuments.in/reader033/viewer/2022060316/5f0c30bf7e708231d4342fae/html5/thumbnails/42.jpg)
Vegetable oil
• Whole batch in the establishment
• The collector does not have any thermalprocessing
• Supplier control?
• Follow up on the contaminated lots:1. Communication to Seremi de Salud Regional
2. Redestination of other lots to products that are not foranimal feeding
• Closure of investigation
![Page 43: Presentación de PowerPoint€¦ · Subtitulo de la presentación en una línea Chilean experience with dioxin contamination in feed Alejandro Pozo Araya, MV Subdepartamento de Alimentos](https://reader033.fdocuments.in/reader033/viewer/2022060316/5f0c30bf7e708231d4342fae/html5/thumbnails/43.jpg)
Conclusions
1. Events that are detected in the early stages of the the chain allow a better containment
2. When further detection in the chain, more complex to find the cause
3. Selfcontrol systems are a valuable tool for theearly detection and alert as a complement to the oficial programmes
4. Surveillance of raw materials offers betterpossibilities to stop possible transfers to theproduction chain and contamination of human products
![Page 44: Presentación de PowerPoint€¦ · Subtitulo de la presentación en una línea Chilean experience with dioxin contamination in feed Alejandro Pozo Araya, MV Subdepartamento de Alimentos](https://reader033.fdocuments.in/reader033/viewer/2022060316/5f0c30bf7e708231d4342fae/html5/thumbnails/44.jpg)
Conclusions
5. Definition of the lot has to be as specific as possible
6. Monitoring of high risk feed minimizeseconomical losses in the livestock production
7. The programme has to be focused on a riskanalysis (ingredients/establishment/type of system)
8. It will not always be possible to find a clearcause for the contamination
