Pacific Northwest seafood companies had made vigorous plans to try to avoid the multitude of cases experienced by meat production companies as their workers headed out for a normally busy summer season, but were unable to avoid a major outbreak. Nearly three-fourths of the 126 people aboard a ship owned by American Seafoods were confirmed to have Covid-19 this week. The ship, just 30 feet shy the size of a football field, large enough for an onboard fish processing factory, was still small enough for the virus to spread among employees working in close quarters. Another contributing factor was that the company's advance quarantine time was only five days; it has since been extended to 14 days.
