Horsemeat scandal: Tesco reveals 60% content in dish

Some Tesco Everyday Value Spaghetti Bolognese contains 60% horsemeat, DNA tests by the retailer have found.

The meal, withdrawn from sale on Tuesday, came from the French factory producing Findus beef lasagne, also at the centre of a row over horsemeat.

Meanwhile, Environment Secretary Owen Paterson has told MPs of plans to test all processed beef in the UK.

Fergus Walsh examines whether there could be any health concerns from eating horsemeat.
