Why is it necessary to test the final product if non-product contact surfaces are positive, but contact surfaces are negative?
Industry should work towards the elimination of Listeria monocytogenes from non-product contact surfaces, as the organism may eventually spread to product contact surfaces and finished products. We feel that testing end-product(s) after 3 positive results from non-product contact surfaces, is a reasonable end point. Please refer to Figure 1 in the policy.
