“The half-life of 0.48 (95% CrI 0.42–0.56) days (12 [95% CrI 10–13] hours) in wastewater shows persistence on a time scale that may lead to exposure of humans or animals when in contact with contaminated wastewater or surface water.”

“…detectable quantities of infectious virus could theoretically persist in refrigerated irradiated raw milk for 45 (95% CrI 33–73) days.”

Figure 3. Violin plots showing results of experimental testing of highly pathogenic avian influenza A(H5N1) virus stability in irradiated raw milk and wastewater and on surfaces, United States. Plots show the posterior distribution of the half-life of viable virus at each condition, determined from the estimated decay rates. Viral decay was calculated for H5N1 virus in irradiated raw milk at 22°C and 4°C, in irradiated wastewater at 22°C, and on polypropylene, steel, and rubber surfaces at 22°C and 4°C. The point at the center of each violin is the posterior median estimate, and the vertical black bars show 95% credible intervals (2.5%–97.5%).
