The World Health Organisation is planning to declare that bacon, sausages and other processed meats cause cancer.
The announcement is expected to list the fry-up favourites in the same category as arsenic, asbestos and cigarettes.
Red meat will also be declared “probably carcinogenic to humans”, and will be ranked as only slightly less dangerous than preserved products, according to a Daily Mail source.
Processed meat, which include pastrami, salami, hot dogs and some types of sausages is made by smoking, curing, salting or adding preservatives.
The World Cancer Research Fund said: “There is strong evidence that eating a lot of these foods [red and processed meat] increases your risk of bowel cancer.”
