Presentation reviewing the relevance of toxic cyanobacteria as a One Health issue. SSWR 4.01B - One Health Problem Solving 2017
Description:
The study of environmental health typically focuses on human populations. However, companion animals, livestock and wildlife also experience adverse health effects from environmental pollutants. Animals may experience direct exposure to pollutants unlike people in most ambient exposure situations, as potable water, foodstuffs and sometimes air designated for human use receives treatment and/or quality control procedures. As most animal exposures are not reduced via these methods, animals may act as sentinels of health risks due to higher exposures, species-specific susceptibilities and shorter lifespans. Examples of One Health environmental issues include toxic exposures to pesticides, lead, mercury, and biotoxins. We will provide an overview of some environmental health issues applicable to the practice of One Health with a special emphasis on harmful algal blooms associated with the occurrence of cyanobacteria and their toxins in freshwater. We will characterize cyanobacteria and their toxins and discuss the effect of anthropogenic activities on their occurrence. Finally, we will describe outbreaks of illness associated with harmful algal blooms in recreational lakes that affected humans and animals during 2009 – 2010 in the United States.
