I have a question relating to testing heavy metals, specifically Cadmium, Mercury, Lead and Arsenic in feed.
I work for a pet food ingredients company where we sell proteins for further processing to the pet food manufacturers.
A big topic at the moment for us is heavy metals testing as it is the key focus of a couple of major customers. We have been testing our products for the 4 heavy metals and reviewing the results against 2002/32/EC and the respective updates (EC 2017/2229, EC 2015/186, etc.) however it has been at the moisture of the product (around 82%) not 12%.
Our lab sub-contracts out to their sister site (I believe) and their test consists of Total Lead, Total Mercury, Arsenic and Total Cadmium. I have spoken to them about testing our products (ingredients) at 12% moisture content however this is not a service they can offer us.
2002/32/EC states in their annexes as the table header a "Maximum content in mg/kg (ppm) relative to a feed with a moisture content of 12 %". These limits, in my opinion, are related to finished products and not ingredients. However we want to adhere to the limits in relation to our product.
Would this be possible to simulate or calculate these for ingredients to 12%. I have been doing a lot of reading however cannot think of an answer.
Any help would be very much appreciated :)
