Polish health authorities ordered the withdrawal of more than 230,000 kilogrammes of pickles, bread and other foodstuff suspected of containing industrial salt today.
The salt was intended for deicing roads in winter.
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.
Nonetheless, following a series of food safety scandals, the Chief Sanitary Inspectorate ordered the withdrawal of suspect food as a preacaution.
Revelations that industrial salt was sold to food producers has prompted authorities to open a criminal investigation and arrest five people.
With much of its territory devoted to agriculture, Poland produces everything from apples and beets to eggs and meat for export.
