Environmental Health Monitoring
Publications

There have been an increasing number of publications on environmental health monitoring in our field. At least 42 peer-reviewed publications have formally evaluated environmental health monitoring. They find that all types environmental health monitoring are superior to soiled bedding sampling at detecting pathogens, regardless of the taxonomic classification of the pathogens.

Below we list all the publications that evaluate environmental health monitoring. Each publication includes a note of the specific pathogens evaluated and sampling types evaluated so you can easily search publications for those that are of most interest of you.
