evidence: The Government says Sri Lankan tests which show high levels of DCD contamination in some batches of Fonterra milk powder are wrong. The Sri Lankan Government has ordered the New Zealand dairy co-operative to recall two batches of milk powder, claiming it contained residue of the farm chemical dicyandiamide (DCD). [...] Low-level residues of DCD were found by Fonterra in milk powder in September 2012, prompting New Zealand's Ministry for Primary Industries to suspend the chemical's use in January this year.
