Dozens of confirmed cases on the mainland
Linked to Costco frozen berry mix
Townsend Farms Organic Anti-Oxidant Berry Blend is being pulled off Costco shelves.
The company has been selling the frozen berry mix nationwide and in the islands.
The Food and Drug administration has linked more than 30 cases of the contagious liver disease Hepatitis-A to the berry mix in several states including: Colorado, New Mexico, Nevada, Arizona, California and Hawaii.
On Sunday, a health department spokesperson confirmed two cases in Hawaii: one on Oahu and one on Kauai -- both said they ate the berry mix then noticed symptoms.
The contagious liver disease can take 30 days to show symptoms.
Many of the cases came from Southern California, where shoppers were surprised to learn what they were putting in their shopping carts.
"My god. That's really shocking," said one shopper.
Costco Hawaii started pulling the product on May 29th.
It's been on store shelves since late February.
"We just used it a couple of weeks ago at a big family breakfast," said another shopper.
Townsend Farms is based in Oregon, but investigators believe pomegranate seeds in the mix from Turkey are the culprit.
Doctors warn anyone exposed should be vaccinated quickly.
As of Sunday, nine people linked to the outbreak had been hospitalized with Hepatitis A.
"It's only a two week period, so every day people have been exposed to this and they delay, they could be missing a chance to prevent this," said Dr. Jeff Gunzenhauser, Los Angeles County Health Dept.
Signs and symptoms of Hepatitis-A typically don't appear until you've had the virus for a few weeks. Watch out for:
--Nausea and Vomiting
--Yellowing of the skin and eyes
--Abdominal pain, especially on your right side beneath your ribs, where your liver is.
Symptoms usually last less than two months -- but may last as long as six months.
Investigators expect the number of cases to rise.
