Stephan Guyenet has a 6 part series called "Is Meat Unhealthy?" In his last post a few weeks ago he addressed this study and here is part of the relevant section:
>This study needs to be interpreted in the proper context. First, it was conducted in mice. Second, the amount of Neu5Gc in the diet was equivalent to a diet composed entirely of beef-- and not just any beef, but the highest-Neu5Gc beef measured in the study (beef Neu5Gc ranges 10-fold). The exposure to dietary Neu5Gc was therefore some 40-fold higher than what most red meat eaters would experience. Still, the study outlines a plausible mechanism for a link between red meat and cancer, and that helps increase our confidence in the observational findings.

I can elaborate a little more, but in short Guyenet is incredibly balanced and professional on this sort of stuff.
