Thank you for your inquiry.
I assume that you are referring to allergy to galactose-1,3-alpha-galactose (alpha-gal) when you mention "red meat allergy." If so, the issue would be whether or not porcine heparin was contaminated with a sufficient quantity of alpha-gal to produce a reaction.
Unfortunately, I am not aware of any studies addressing this issue, and could not find any reference to it on a literature search. However, I assume it would be unlikely that a sufficient amount of alpha-gal would be present in porcine heparin.
Thank you again for your inquiry and we hope this response is helpful to you.
