COVID-19 outbreaks are spread through food processors that produce potato chips, breadsticks, and beef jerky in Oregon.

Oregon now has 60 workplaces where active COVID-19 outbreaks have sickened five or more people, state health officials revealed in a weekly report. That’s a 48 increase on July 8. At least 15 of those outbreaks are in food processing plants.

In Umatilla County, the eastern Oregon county that has become the state’s viral epicenter, dozens of people became ill while working at two jails, two potato processing plants, and a Walmart distribution center. Lamb Weston, the Hermiston company that packs frozen potato chips, has 142 COVID cases.

Among the largest active outbreaks in the Portland metro area is an Amazon warehouse in Troutdale, where 24 people have become ill. The count at that location last week was 15 cases.

The report comes a day when Oregon reported 282 other cases and four deaths.

Businesses across Oregon have struggled to limit the spread of COVID in warehouses, especially food processors, which account for the bulk of active outbreaks. Those plants include Teeny Foods in Gresham (he makes 27 breadsticks), Shearer’s Foods in Hermiston (potato chips, 21 boxes), Old Trapper in Forest Grove (beef jerky, 19 boxes), Mary’s Harvest Fresh Foods in Portland ( watermelon cubes, 15 boxes). Kraft Heinz and Tofurky now have groups of six and five cases, respectively.

The state’s largest outbreak outside the Oregon Department of Corrections remains Pacific Seafood in Newport, which contains frozen fish sticks and smoked salmon.

Meanwhile, the state released new charts showing the sharp rise in new infections among people in their 20s, which make up the plurality of new cases in the past two months.
