It is now known that the air quality in buildings used for animal production can affect the workers' quality of life and health as well as the performance of the animals. Although this reality is well known for swine production, no study deals with veal calf breeding, which is expanding. The aim of this study is to characterize and quantify, by season, the chemical substances and biological agents present in the air of veal calf production buildings, to determine the risks for people in relation to standards and guidelines, and then to propose simple and not very costly quality criteria for building managers to improve air quality, if needed. This study's recommendations will be disseminated to the stakeholders in the veal calf production industry, and an action grid will be made available to them so that they can make the relevant changes.
