Food watchdogs have warned a portion of standard cooked sausages contains more than a third of the recommended amount of salt for an adult.

The amount of salt in sausages has risen over the last 12 years from 2.2g per portion (two sausages) to 2.4g. The recommended daily amount for an adult is 6g.

Deputy chair of the FSA, Julia Unwin, said: "Sausages are popular, but our survey shows that their salt levels are still too high." She warned that having too much salt in your diet can contribute to two of the big killers in the UK - heart disease and stroke.

Unwin said that manufacturers and retailers are starting to respond to the Agency’s calls to reduce the amounts of salt and fat in their food, but urged them to "go further" and "play their part in improving the nation’s health."
