The Centers for Disease Control and Prevention now lists a hepatitis A illness in Washington as a "probable case" in the outbreak linked to frozen berries sold at Costco.
A man in Thurston County was sick in March, but has since recovered. The outbreak now includes 79 cases in eight different states.
Townsend Farms Organic Anti-Oxidant Blend frozen berries were grown in Oregon and sold at Costco stores in Washington. The berries have been recalled.
The Washington state Department of Health advises anyone who has this brand of frozen berries to discard the remaining product. Additionally, the DOH says to contact your medical provider if you have consumed the berries in the past two weeks and never had the vaccination for hepatitis A nor had the disease.
Costco announced it was offering free vaccinations for anyone who had eaten potentially-contaminated berries.
