Why isn't all pork being screened for Covid-19?

"The halting of a British pork plant’s sales to China after just a few workers contracted coronavirus highlights the risk that more facilities around the world could see exports disrupted."

Dr. Immo Norman Fiebrig from Germany, a licensed pharmacist and PhD in biochemistry explains his ‘Corona Triangle Hypothesis’ where mapping cases of COVID-19 in humans in the State of Santa Catarina in Brazil over maps of factory pig farms, reveals a strong overlap between high pig densities and high COVID-19 infection rate in humans in spite of relatively few people living there.

Hypothesising on the emergence of SARS-CoV-2 through bats: Its relation to intensive pig-factory farming and the agro-industrial complex 

 "The emergence of SARS-CoV-2 and the resulting disease, COVID-19, is possibly related to bats, which have been shown to be a reservoir for many kinds of viruses, including coronaviridae, due to their physiological peculiarities. However, it remains controversial how, if at all, the virus evolved from bats to become infectious to humans, turning the resulting disease into a pandemic. The current discussion is based on some facts around the agro-industrial complex, such as intensive pigfactory farming in the city of Wuhan and its surroundings. A putative triangular relationship between bats, pigs and humans is described as a striking fictional story first, serving to illustrate the hypothesis. Then the history of current globalised animal farming from its beginnings during the 'Green Revolution' and its detrimental impacts are summarised. With COVID-19 research in its infancy, this is followed by mappings of pigfactory farming in the state of Santa Catarina, in the south region of Brazil and outbreaks of COVID-19 in humans."
