Peru has placed a temporarily ban (180 days) on all Brazilian beef, while Egypt has specifically banned beef from Mato Grosso state.
The Brazilian will receive a negative effect on the beef exporting. The Brazilian beef exports to Egypt, for the first four months of the year totalled 48,450 tonnes swt, up 91% year-on-year, with shipments from Mato Grosso state representing 25% of total exports or 12,074 tonnes swt. Since 2001, Egypt has been one of the major destinations for Brazilian fresh beef, averaging 110,000 tonnes swt annually for the last five years.
