Sausage manufacturers have been accused of failing to cut salt levels to meet public health targets.
As a result some brands and supermarkets are putting customers at risk of overdosing on salt, say campaigners.
The lobby group CASH says salt, which is linked to raised blood pressure and strokes, has become a ‘forgotten killer’.
Its research suggests that eating a sausage sandwich for breakfast could contain nearly two-thirds of an adult’s maximum daily recommended intake for salt, which is 6g.
