Italy ordered a recall yesterday of mozzarella cheese potentially contaminated with cancer-causing dioxin, as a widening health scare tainted the reputation of one of its best-known culinary products.

Italy's Health Ministry said it was withdrawing products from 25 companies in Campania region, where Italy's best buffalo mozzarella is produced.

France briefly prohibited sales of some Italian mozzarella yesterday, but revoked the ban hours later after winning Rome's assurances that none of the suspect cheese was exported there. Japan and South Korea had already blocked imports.

The European Commission, which had previously threatened a trade ban unless Rome acted more aggressively, said it was satisfied with Italy's latest effort to contain the scare.

Italian Foreign Minister Massimo D'Alema played down the health risks even as he announced a recall affecting an industry which employs 20,000 people and is worth about €300 million a year. "This is a limited phenomenon and once the (recall) measures are completed, we're convinced that we can restore confidence in the quality of a product that remains a symbol of Italian gastronomy," he said.

In Brussels, the European Commission said Italy had also pledged to carry out "constant monitoring" of production sites to ensure no further cases of mozzarella cheese were found with dioxin levels exceeding EU limits.
