Magnetic chicken products from WOOLWORTHS

My brother in law bought some Woolworths organic free range chicken breast fillets from the Woolworths store in Claremont, together with some Woolworths chicken viennas,and decided to check the meat for magnetism. After making sure that the meat was thoroughly dry and the viennas, he held a magnet to the meat and the magnet stuck to both of the products successfully, even when he shook the meat. In light of the fact that amongst other material, both foreign and harmful to the human body, which seem to be being added to many consumer products, ie: graphene oxide etc, I'd like to know what excuse Or explanation Woolworths has for this fact, as I see I am not the only Woolworths customer who has found the same thing with chicken bought from Woolworths?I have authentic video proof of this if needed. I can be contacted via email as above. I eagerly await your response
