1 Trace Minerals Quality Challenges and Protecting our Business Tara Jarman Alltech Asia-Pacific Quality Assurance Manager Asia-Pacific Biosciences Centre Thailand

2 Why is Quality Important? Because 80% of the 1000 European nutritionists questioned as part of a feed industry survey said that: Quality is the No.1 or No.2 most important factor when selecting a feed additive supplier

3 Why is Quality Important? E. Coli DIOXINS melamine SALMONELLA PCB s GMOs 2008 Alltech, Inc. All Rights Reserved.

4 Producers are not food chain oriented

5 Recycling is not HACCP-friendly!

6 Mined versus Re-cycled Minerals Mined minerals tend to be higher in heavy metal contamination (Cd) Mining gprocess can cause contamination with dioxins/pcbs Recycled materials dioxin formation Recycled materials PVC coating and other material not removed before processing

7 Factors in contamination Trace minerals from inorganic salts (sulphates & oxides) are produced in large continuous batches Batch contamination is not homogeneous pockets of heavy contamination Industrial applications dominate ceramics & fertilisers Food chain business is not key to high-volume suppliers QC is geared to non-food clients

8 Feed Contaminations March 2008 Australia High lead levels in pig livers Traced to contaminated zinc oxide imported from China Pre-mix manufacturers, pig producers Recalled initiated Discrepancies in COA s, batch numbers 2008 Alltech, Inc. All Rights Reserved.

9 Heavy metal testing results Asia-Pacific July 2009

10 Methodology 100-gram samples of the following were collected Inorganic mineral premixes (pigs, poultry, aqua, pets) Zinc oxide, zinc sulfate, Copper sulfate Ferrous sulfate Chelated zinc, copper Chelated mineral premix Organic selenium, Sodium selenite Manganous sulfate, Manganous oxide

11 Methodology Total samples submitted Thailand 37 Philippines 51 Malaysia 19 China 21 India 21 Australia 11 Pakistan 24 Taiwan 9 Vietnam 17 Total 210
