Two outbreaks of botulism in central Saskatchewan in which mortality of waterfowl continued into late autumn and then recurred in the same marshes the following spring are described. Small numbers of birds were involved in each instance. Dabbling ducks (predominantly mallards, Anas platyrhynchos and pintails, Anas acuta) and American coots, Fulica americana were affected most commonly in autumn, whereas only diving ducks (predominantly lesser scaup, Aythya affinis) were found to be involved in spring. Live maggots present in carcasses despite sub-freezing temperatures were the probable source of intoxication in the autumn; the source of toxin in the spring was not determined.
本文描述了萨斯喀彻温省中部发生的两起肉毒中毒事件，水禽的死亡持续到深秋，次年春天在同一湿地再次发生。每次事件涉及的鸟类数量都很少。在秋季，涉禽（主要是绿头鸭、绿头鸭和尖尾鸭）和美洲白骨顶最常受到影响，而在春季，仅发现潜鸭（主要是小潜鸭）受到影响。尽管温度低于冰点，但尸体中存在活蛆虫可能是秋季中毒的来源；春季毒素的来源尚未确定。
