Poland - Tons of Food Recalled Over Contamination - NYTimes.com Polish health authorities on Friday ordered the withdrawal from the market of more than 500,000 pounds of pickles, bread and other food suspected of containing industrial salt, the latest development in a scandal raising fears about food safety. Revelations that industrial salt, intended for deicing roads in winter, was sold to food producers have prompted a criminal investigation and the arrest of five people. Laboratory tests so far have found that the amounts of dioxins and heavy metals in the salt are minimal and unlikely to harm human health.
