PRESTON, ENGLAND – OCTOBER 13: Pigs looks on while in a barn on October 13, 2021 in Preston, England. British pig farmers say a combination of Brexit and COVID-19 has led to an exodus of migrant workers from abattoirs and meat processors. This leaves pigs to over-fatten on units across the UK. Once over a certain weight, abattoirs charge penalties for handling the animals leaving many farms unable to afford their services. The National Farmers Union warned recently that up to 150,000 animals would have to be culled by pig farmers. (Photo by Nathan Stirk/Getty Images)
