Results from LimitationRecognizer: We detected the following sentences addressing limitations in the study:A limitation of this work is that our analysis focused on a one-hour exposure duration of the susceptible worker to contaminated plastic packaging. This duration was selected as the timing and number of products arriving in a receiving warehouse beyond one hour was unpredictable. However, when extending this to an 8-hour shift, cumulative fomite risks remained very low (handwashing and mask use: 7·5 × 10−5 [95%CI: 1·8 × 10−7-1·7 × 10−4]). A second limitation is that there are limited data on the concentration of the Delta variant shed by infected individuals, beyond the Ct value that estimates approximately 6 × 105 copies/mL in oropharyngeal swabs.83 To simulate increased infectiousness/transmissibility of Delta or other VOC, we increased infectious viral shedding among the infected workers (2-, 10-, and 100-fold), which equates to 2·4 × 106 to 2·4 × 109 infectious virus/mL of saliva. While the Delta variant should clearly fall within or below this range of increased viral shedding, this analysis can be refined as more data become available. This would also serve to reduce the uncertainty in this and other parameters which result in a dynamic range in risk estimates and confidence intervals. Using QMRA modeling, we find that susceptible workers (unvaccinated, no precautions) in frozen food packaging facilities are at low risk of SARS-CoV-2 fomite-mediated transmission (exposure to large droplets and small aerosol particles on plastic packaging) under cold-chain conditions.
