Sao Paulo , Brazil ( CNN ) -- The U.S. Food and Drug Administration said on Friday it had detained shipments of orange juice and concentrate from Brazil and Canada after finding traces of the unapproved fungicide carbendazim . The agency discovered the substance in 11 shipments , six from Canada and five from Brazil . The FDA said it had detained nine of the shipments because companies behind two of the shipments withdrew their import request . The fungicide is allowed in limited quantities across Europe and Latin America , but the United States banned its use in 2009 . The levels found by the FDA are below international maximum levels . Earlier this month , the FDA temporarily halted all orange juice imports after low levels of carbandazim were found in some juice shipments from Brazil . It later declared that the juice posed no health risks , but that it would analyze all incoming shipments for even trace elements of the banned fungicide . The controversy has sent orange juice prices skyrocketing . Brazil is the world 's biggest exporter , accounting for 85 % of total global exports . The United States is its second-biggest market after Europe . The FDA has collected samples from 80 shipments of orange juice . So far , 29 have tested negative for carbendazim .
