Brazil has ordered three more meat processing plants to suspend production as it investigates allegations that beef processors exported rotten or tainted beef to foreign countries.

The investigation started with 21 plants, six of which were ordered closed by Brazilian health authorities, reports Reuters. The remaining 15 plants are not allowed to export but may produce food for the domestic market. The three newly closed plants are in Parana state, where the scandal has been centered.

Since the scandal broke, several countries have banned exports of Brazilian beef, though some like China and Chile have resumed exports.  The country’s government is working with the European Union and other countries to restore confidence and resume exports.
