• Pasteurization was shown to successfully inactivate SARS-CoV-2 in human breast milk. Conzelmann et al. spiked five different virus isolates from Germany, France, and the Netherlands into five individual milk samples. Incubating the milk samples at room temperature for 30 minutes resulted in a 40.9-92.8% drop in viral titers, and after pasteurization no further residual infectivity was detected in any of the samples.
