Description

This project addresses the risks posed by the spreading of manure and emissions released into the environment to the biosecurity of farms, as well as to the health of workers and nearby populations. Considering the nature of the contaminants present in manure (dust, odours, bio-aerosols), the research team asserts that there are considerable risks to animal health, human health, and the environment associated with the spreading of manure on farmlands. We believe that by acquiring more knowledge about emissions and modifying spreading techniques accordingly, it is possible to limit the spread of disease, reduce environmental impacts, and improve biosecurity protocols.

Objective(s)

In order to assess and lower the risks associated with the spreading of manure, this project aims to

  • quantify fugitive emissions of air contaminants following the spreading of manure;
  • assess the biosecurity risks associated with these emissions; and
  • determine the most effective risk-lowering strategies and test them in the field.

From 2019 to 2023
