baby formula

Question

enfamil nutramigen hypoallergenic formula does not bear an OU hechsher. It seems to be the only product in the enfamil line that does not have an Hechsher. The reason, according to the company customer service in Canada, that they use Porc pancreatic enzymes to hydrolise the proteins in the formula to render them hypoallergenic. You are listing this product as Kosher for Passover 2004 Are you still standing by this? and why? Is the american production different then the Canadian version? Thanks
