MOSCOW, Nov 23 (Reuters) - Russia will resume beef and pork imports from 12 subsidiaries of Brazilian producers from Nov. 25, its agriculture safety watchdog said in a statement on Tuesday. Most of the Russian restrictions on Brazilian beef and pork producers have been in place since 2017 due to alleged use of the feed additive ractopamine. Brazilian meat industry groups have denied using the additive. Moscow allowed beef imports from another three units of major Brazilian beef exporters last week as it moved to boost domestic supply. read more Further supplies will resume from nine units producing pork and three units producing beef from Thursday, the watchdog, Rosselkhoznadzor, added. It did not name the producers. "Rosselkhoznadzor continues to work on expanding the list of Brazilian producers certified to supply beef to Russia," it said. Brazil"s biggest beef processors – JBS SA (JBSS3.SA), Minerva SA (BEEF3.SA) and Marfrig Global Foods SA (MRFG3.SA) – did not immediately respond to requests for comment. Russia plans to set a duty-free import quota for up to 200,000 tonnes of beef in 2022 to boost domestic supply as part of measures the government hopes will help stabilise domestic inflation, which is at a five-year high. For Brazil - the world"s largest beef exporter - Russia is a promising market as its exports to China were temporarily suspended in September after two atypical cases of mad cow disease were reported in the South American nation. At the time, Brazil"s Agriculture Ministry stressed that the two cases had generated spontaneously and were not related to contaminated feed, as in classic mad cow disease. Since the cases in cattle were announced, Brazil has also reported two cases of the neurodegenerative Creutzfeldt-Jakob disorder in people, though agriculture officials said they were not related to beef consumption. read more Reporting by Polina Devitt Additional reporting by Roberto Samora in Sao Paulo Editing by Louise Heavens, Jan Harvey and Aurora Ellis
