Food for thought

Each day we seem to hear another supermarket has taken food off its shelves as its products contain horse, and now today a council has announced a local school has been serving food to children with traces of horse in the meals.

How do we know we’re not eating dog? Is this kind of thing checked? Before this scandal I would have assumed that all meat was tested at some point.

Thanking you in advance.
