The horse meat crisis has led the world’s largest food manufacturer Nestle to test for the presence of meat such as kangaroo and dog, according to the head of food safety at the firm’s research centre Dr John O’Brien.

As reported in the Irish Times, Dr O’Brien, a former head of the Food Safety Authority of Ireland, people working in food safety had now become molecular detectives. “Not only are we concerned with horse, we are also keeping an eye on kangaroo, dogs, goats and a few other species and asking questions. Could any of these find their way into the food chain? So we have probes for all of those.”
