     "text": "This study provided the first baseline data on AIV occurrence in groundwater and documented the methods and challenges of conducting such a study during an ongoing animal health event. Results indicated that AIV was present in groundwater underlying poultry operations. Three wells and one lagoon were positive for the influenza A matrix gene. One well was positive for the H5 subtype that matched the outbreak virus gene although confirmatory cell culture and embryonating egg culture for live viruses results were negative. In addition, seven wells were positive for the poultry parvovirus, which provided supporting evidence for virus transport pathways between avian fecal wastes and groundwater."

All samples were analyzed for the influenza A matrix gene, the H5 subtype, and the poultry parvovirus."

HPAIV outbreaks in commercial poultry in the United States have historically been rare events, with only three outbreaks documented prior to 2014\u201315 (1924, 1983, and 2004)."

Results of this pilot study provide information to guide future studies addressing AIV and other pathogen transport to groundwater. The scope of this study was limited to an evaluation of the occurrence of AIV in groundwater. Potential next steps include an evaluation of the risks that AIV in groundwater presents to poultry, other animals, and humans."
