The company had suspended production at ten of its 36 Brazilian meat plants in the wake of the Brazilian meat scandal, which saw allegations of rotten and dangerous meat having been sold and public officials bribed.

As a result, the EU and China, some of Brazil's biggest markets, along with other countries put a ban on imports from the country.

This resulted in a huge decline in demand for meat from Brazil, causing JSB to suspend production at 10 plants at the end of March and put staff on leave.

The remaining four plants are to return on 2 May.

JBS along with other meat processors were undergoing investigations following the accusations.

EU ban still in place

China, Chile and Egypt have since lifted the bans on imports of meat from Brazil. However, the EU is continuing to block meat from plants caught up in the scandal.

The US has not imposed a ban on imports from Brazil, angering US farmers. Ranchers-Cattlemen Action Legal Fund (R-CALF), which represents US cattle producers, is seeking 100,000 signatures for its petition to block imports from Brazil until all beef is labelled with its country of origin.

The petition was filed on the White House’s "We the People" website and needs 100,000 signatures by 13 May to get an official response from the White House.
