A horse walks into a Burger King... but where is PETA?

A case of speciesism that should be scoured and cleansed from the history of this fine institution, I submit:

Burger King announced Thursday that it had terminated its relationship with European supplier Silvercrest Foods after finding traces of horse meat in beef patties at a Silvercrest facility.

So what if some horse wants to participate in the feast? I mean, where does speciesism stop?

Methinks PETA should get onto the act and learn them.
