Dog poisonings associated with a Microcystis aeruginosa bloom in the Netherlands

Abstract

In early autumn 2011, three dogs died after they had been exposed to a Microcystis aeruginosa bloom on Lake Amstelmeer, The Netherlands. The cyanobacterial scum from the lake contained up to 5.27 × 103 μg g-1 dry-weight microcystin, the vomit of one of the dogs contained on average 94 μg microcystin g-1 dry-weight. In both cases, icrocystin-LR was the most abundant variant. This is the first report of dog deaths associated with a Microcystis bloom and microcystin poisoning in The Netherlands. © 2013 by the authors; licensee MDPI, Basel, Switzerland.
