Is it OK to combine food and feed pallets in a trailer?

Dear Sir/Madam, 

I am working for a dutch company who wants to achieve the BRC S&D certification. We are a transport company and we transport the product groups Food and Feed (animal feed). All products we transport are packed and sealed on a pallet, which makes the level of contamination lower.

Is it allowed to combine these two product groups in a trailer (like 10 pallets Food - 10 pallets Feed) when we have the BRC S&D certification? And which document makes that clear? (because i couldn't find it)

Thank you very much for your reply!

Hi,

...it depends.. What products? How packed? What possible interference? Do you can more details please
