Additionally, FDA notes in the COVID-19 Transport Media Policy that it would be helpful to theFDA if manufacturers additionally provide information on their expected manufacturing capacity of their transport medium in their notification discussed above. A recent study by Public Health England [3]investigated a wide array of apparent inactivation reagents in current use in UK laboratories during the COVID-19 pandemic for sample transportation and subsequent molecular processing. Cotton swabs/toothpicks/dry swabs will not work for reasons described above in the section on anaerobic cultures. Standard UTM and VTM media were designed for transporting intact viable microbial samples for culture, this means that there is still a biohazard which requires a controlled environment for subsequent laboratory work. As discussed in section IV.B.4 of the COVID-19 Transport Media Policy, FDA is interested in interacting with commercial manufacturers of alternative formulations of viral transport media that may wish to discuss alternative approaches to validation that are not identified in the policy.
