Aim: To analyze group A rotavirus (RVA) environmental contamination in waters used for 
calves? consumption and to assess viral viability in dairy farm water sources. 
Methods and Results: We analyzed 202 samples of water used for calves? consumption and 
RVA was detected by RT-qPCR in 35.1% (95%CI: 28.9?42.0%). A marked pattern of seasonality 
was observed with higher frequency of detection in colder than warmer months (p=0.002). 
There was no association between viral load and season or between the number of milking 
cows in the herd and the detection of RVA in the farm. The viability of the RVA particles 
detected was confirmed by isolation of RVA in cell culture from 5/10 water samples. 
Furthermore, an RVA waterborne outbreak of neonatal calf diarrhea was described. 
Conclusions: We demonstrate that RVA is frequent in dairy farm waters, and that the virus is 
infectious and capable of generating a diarrhea outbreak. 
Significance and Impact of Study: Neonatal diarrhea syndrome leads to economic losses to the 
livestock industry worldwide. To determine transmission routes is essential to take action in 
this regard and reduce the impact that this syndrome has for the livestock production. The 
results obtained in this work alerts the dairy industry and highlights that mitigation strategies 
are crucial to improve the microbiological quality of this water.
