According to this article some British sausages are made up of as much as a third fat and only 32 per cent meat. The rest of the sausage is usually made up of ground wheat rusk which is used as a bulking agent to cut costs and improve the texture of the sausage. A study has been carried out on 36 brands of sausages including the country’s biggest sellers to find out exactly what goes into them. Researchers for the journal Meat Science looked at the packaging for information on meat fat and salt content. On average the sausages contained 62 per cent meat but four of the sausages that were looked at had less than 50 per cent and the worst one had less than a third pork. The study did not identify the different brands but did reveal that the two sausages with the lowest meat content were Asda Smart Price with 34% pork and Sainsbury’s Chipolatas with 32% pork.
