Some 20 meat production factories have closed due to mass spreading of COVID-19, in fact, Tyson meats in Wallula is temporarily closed due to 250 workers at the 1400 person plant have tested positive for the virus. So with so many factories shutting down meat production has slowed tremendously.

Costco implemented rationing so it's members will be able to get what they need and is a temporary measure.

As far as the mask policy here's what a Press release from Costco says:

Dear Costco Member,

To help protect our employees and members, effective May 4, 2020, all Costco members and guests must wear a face covering that covers the mouth and nose, at all times while at Costco. This requirement does not apply to children under the age of 2 or to individuals who are unable to wear a face covering due to a medical condition.

Costco employees are required to wear face coverings, and now we are asking that Costco members do so too. We know some members may find this inconvenient or objectionable, but under the circumstances we believe the added safety is worth any inconvenience. This is not simply a matter of personal choice; a face covering protects not just the wearer, but others too.

In short, we believe this is the right thing to do under the current circumstances.
