The Food and Drug Administration said Friday that it had detained orange juice shipments from Canada after they tested positive for low levels of a banned fungicide previously found in Brazilian juice. The FDA announced earlier this month that it would begin testing foreign orange juice shipments for the presence of the fungicide carbendazim before allowing them to enter the country.
