From Forbes...
“The five cases do in fact seem connected. Four of the five cases have been from Pierce County with the remaining one being from Thurston, the neighboring county. Whole genome sequencing has shown that the bacteria from each cases have similar genetic fingerprints, strongly suggesting a source of the bacteria in common. However, authorities have yet to identify what specifically this source may be. Therefore, at this point, they can’t determine what food may need to be pulled from the market.
Probably the food they hand out to those in need.
One of those meals.
