 Hundreds of meatpacking workers at a single BRF SA plant in southern Brazil have tested positive for the novel coronavirus, the company said on Monday, amid global concerns about the pandemic disrupting food supplies. Brazilian meatpacker BRF said in a statement that nearly 340 people, or 6.6 of workers, at its Concórdia plant in Santa Catarina state had tested positive for the virus. The workers have been preemptively suspended from work based on the positive results from rapid testing and will now be submitted to slower but more accurate molecular diagnostic testing, BRF said.
