Chinese meat importers and processors have called on exporters in countries with Covid-19 outbreaks to step up checks on shipments before they are sent to the world’s biggest market, Reuters quoted the country’s top industry group as saying.

“China has been importing a large quantity of meats this year, and has detected virus on the packaging of cold chain products many times, even as lots of disinfection has been done domestically,” Gao Guan, spokesman for the China Meat Association, said by telephone on Tuesday.

“It should be better to handle this (virus control) at the meats exporting origins, and carry out disinfection at the production plants,” as the cost would be lower, and efficiency higher, Gao added.

China has ramped up disinfection and virus testing on frozen food after it found coronavirus on imported products and packaging.

The measures have pushed up costs, disrupted trade, and irritated major exporters.
