Zinc chromate poisoning in calves

Extract

Losses in dairy cattle have occurred recently in which the clinical symptoms and general postmortem picture would suggest that an irritant poison was the cause of death. In these particular cases, zinc chromate paste* * A paste used by the State Hydro-electric Department for joining sections of steel-cored aluminium power conductors on cross-country transmission lines. had been used in the vicinity of the stock concerned just prior to the first mortalities. It was therefore reasonable to suggest that, in addition to the more common stock poisons, tests for zinc chromate should be made on the specimens submitted for toxicological examination.
