Public health aiuthorities in Thailand are warning against excessive use of preservatives in processed meat, saying that high concentrations of nitrite and nitrate salts in food have been linked to an increased cancer risk.
The Department of Medical Sciences recently released the results of a three-year food safety surveillance, which found high concentrations of nitrate and nitrite salts in popular processed meat products. The salts are commonly added as preservatives because they maintain the product's colour and inhibit bacterial growth.
