Cancer alert raised over sausages and ham

Eating sausages, ham and other processed meats causes colon cancer, and red meat probably does too, an arm of the World Health Organization said on Monday.

The findings support recommendations to limit intake of meat, said the International Agency for Research on Cancer, which compiled a review of more than 800 studies on the link between a meat diet and cancer.

"In view of the large number of people who consume processed meat, the global impact on cancer incidence is of public health importance," agency official Kurt Straif said in a statement.

For an individual, the risk of getting cancer from eating processed meat is statistically small, the agency said, but "increases with the amount of meat consumed".

"Each 50-gram portion of processed meat eaten daily increases the risk of colorectal cancer by 18 percent."

The report was compiled by 22 experts from 10 countries.

The evaluation revealed "strong mechanistic evidence supporting a carcinogenic effect" for red meat consumption - mainly for cancer of the colon and rectum, but also the pancreas and prostate, said the agency, which is based in Lyon, France.

Red meat includes beef, veal, pork, lamb, mutton, horse and goat.

As for processed meat, including hot dogs, sausages, corned beef, dried meat such as beef jerky or South African biltong, canned meat or meat-based sauces, there is "sufficient evidence in humans that the consumption of processed meat causes colorectal cancer".

Meat can be processed in various ways, through salting, curing, fermentation or smoking.

Given that red meat is an important source of human nutrition, the results should help governments and regulatory agencies balance the risk and benefits of eating meat, the agency said.

It did not state whether the cooking method of meat affects the cancer risk.

The agency added processed meat to the same category of cancer-causing agents as tobacco smoke and asbestos, but stressed this did not mean it was just as dangerous.
