In addition, provided blood sampling is necessary for antibody tests, additional issues (linked to logistics, employee comfort, information privacy, etc) will be raised.

Company leadership ultimately decided to combine mandatory PCR screening with voluntary IgM and IgG screening. The company decided on pilot screenings at two U.S. production plants. Screenings involved mandatory viral testing (through reverse transcription polymerase chain reaction) and optional antibody testing (both immunoglobulins G and M). Pilot screenings showed benefits along with limitations: (1) detecting asymptomatic infections, but at questionably relevant time points; (2) identifying infection clusters, but with uncertain sites of transmission; (3) showing relatively low rates of infection, but absent details for meaningful community comparisons. Establishing a worker screening process was an enormous undertaking. Company employees had to stretch job roles and were distracted form usual responsibilities. Whether other companies would find sufficient benefits to justify similar screening is unclear. Moving forward, new Federal leadership could provide greater support for,?and assistance with, worker screenings. In addition, new technologies could make future screenings more feasible and valuable.

If food production wanes, the problem can only worsen. To keep our food supply thriving, it is imperative to keep production workers safe. During the COVID-19 pandemic, production worker safety has meant additional protections beyond the routine: added engineering controls (e.g. ventilation, air filtration, physical barriers); new procedures (e.g. staggered work shifts, symptoms screenings, contact tracing); and extra personal safeguards (e.g. hand sanitizer, face shields, universal masking). Early guidance about such protections came from several sources: the World Health Organization;8 , 9 the Occupational Safety and Health Administration; 10 and jointly from the U.S. Department of Health and Human Services and the Centers for Disease Control and Prevention (CDC).11 However, completely lacking from early COVID-19 guidance were recommendations around an essential issuetesting for the causative virus, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Some information about SARS-CoV-2 testing came from the CDC; but recommendations were limited to situations where a COVID-19 case had already been identified.12 Other CDC testing guidance was general in nature, not specific to a food production workforce.13 In addition, testing to screen for asymptomatic infections was not addressed. Without screening for asymptomatic infections, some food producers had outbreaks.14 , 15 A few facilities had to close.16 At the same time, emerging literature was making clear the problem of asymptomatic (and presymptomatic) COVID-19 spread.17 Purpose Toward identifying asymptomatic/presymptomatic cases, one company, Danone North America, thought a worker screening strategy could be of benefit. Danone North America (from here forward, the company) has approximately 6000 employees across the U.S., with approximately 3000 production workers in 16 US food production facilities. In deciding to undertake a worker testing pilot, the company had several aims: first, enhancing worker safety; second, keeping plants open to produce needed food; third, generating knowledge to benefit other critical infrastructure workersincluding employees at other food companies. In April 2020, when the company began considering SARS-CoV-2 worker screenings, the goals were essentially threefold: (1) detecting asymptomatic (or presymptomatic) infections before opportunity for spread; (2) identifying clusters of cases to indicate potential breakdowns in facility protections; (3) assessing overall workplace safety by comparing company results to community rates. Methods While consideration was given to different SARS-CoV-2 tests, reverse transcription polymerase chain reaction (PCR)specifically with nasopharyngeal samplingseemed to be the emerging test standard.18 Nonetheless, for worker comfort, less invasive nasal sampling was thought to be preferable. Reassuringly, such nasal sampling seemed to have similar sensitivity.19 Regardless, with either type of sampling, in relying on a PCR-only Rabbit Polyclonal to Histone H2B Phellodendrine strategy, it was recognized that SARS-CoV-2 infections could be missed.20 A potential solution Phellodendrine was thought to be add-on antibody testing. Early thinking was that add-on antibody.
