While this is not required by the state or local health departments, Friday’s press release referenced the Centers for Disease Control and Prevention recommendations, which state that wearing masks in public settings will help prevent the spread of COVID-19.

No known transmission through food or food packaging
There is no known evidence that COVID-19 is spread on food or on food packaging, according to the Oregon Health Authority and the Oregon Department of Agriculture. Therefore, even if someone on a farm or working in processing plant tests positive for COVID-19, food from that location doesn’t need to be recalled from supermarkets or restaurants after it's sold, the agencies said.
The OHA maintains that COVID-19 is generally spread from person to person through respiratory droplets when an infected person coughs or sneezes. In addition to wearing masks in public, the OHA still recommends that people wash their hands often. Wash for 20 seconds before and after preparing meals, before eating and after coming home after leaving the house.
