A chicken processing plant in Canada has been forced to close after 28 employees tested positive for COVID-19.

Vancouver Coastal Health (VCH) said that all employees at the United Poultry Company Ltd. in East Vancouver have been told to self-isolate following the discovery of an outbreak at the plant.

VCH became aware of the issue after receiving a positive test on Sunday. The agency tested all 71 workers at the plant the next day, and more than 20 tests came back positive.

The plant closed on Monday.

VCH said that it isn't necessary to recall any chicken products distributed from the plant.

"At this time, there have been no reported cases of food or food packaging being associated with the transmission of COVID-19," the regional health authority said.

The B.C. Chicken Marketing board reassured a reporter on Sunday that the chicken supply in the province remains "intact," although it's unclear whether the latest closure will impact that.

The news comes just one day after an Alberta meat-processing plant announced that it would temporarily close its doors due to a COVID-19 outbreak.
