All infections traced to product sold at Costco stores, agency says

TUESDAY, June 11 (HealthDay News) -- The number of people sickened in a hepatitis A outbreak that may be tied to a frozen berry/pomegranate mix now stands at 87, U.S. health officials said Tuesday.

As of June 10, cases had been reported in eight states: Arizona, California, Colorado, Hawaii, Nevada, New Mexico, Utah and Washington. The number of cases is expected to rise as the investigation continues, according to the U.S. Centers for Disease Control and Prevention.

The CDC said the hepatitis A cases may be connected to Townsend Farms Organic Antioxidant Blend frozen berry and pomegranate mix.

The agency said 36 people who were sickened have been hospitalized, and no deaths have been reported. Forty-six of 68 ill people interviewed (70 percent) reported eating Townsend Farms Organic Antioxidant Blend frozen berry and pomegranate mix.

On June 4, Oregon-based Townsend Farms recalled the frozen berry mixes, which were sold to Costco and Harris Teeter stores. The mixes were sold under the Townsend Farms label at Costco and under the Harris Teeter brand at that chain of stores, the Associated Press reported.

All of those sickened said they'd purchased the product from Costco markets. No cases have been traced to product bought at Harris Teeter, the CDC said.

Costco has removed the product from its shelves and is notifying members who purchased the product since late February 2013, the CDC said.

Preliminary laboratory analyses of specimens from two states suggest the hepatitis A strain responsible for the outbreak is rare in North America but is common in Africa and the Middle East. The strain was pinpointed as the cause of a recent hepatitis A outbreak in Europe linked to frozen berries, and to a 2012 outbreak in British Columbia associated with a frozen berry blend with pomegranate seeds from Egypt. But, there's no evidence that these outbreaks are related, the CDC said.

The label on the Townsend Farms product says it contains products from the United States, Argentina, Chile and Turkey.

According to the World Health Organization, hepatitis A illnesses typically arise within 14 to 28 days of infection. Symptoms may include nausea, fever, lethargy, jaundice and loss of appetite. There's a vaccine against hepatitis A, and it may ease symptoms if given soon after exposure to the virus.

Berry Habit May Help Women Avoid Heart Attacks

Jan. 14, 2013 -- Young and middle-aged women who eat blueberries and strawberries regularly may help lower their risk of a heart attack later.

In a new study, researchers wanted to focus on whether substances known as anthocyanins are good for the heart.

Anthocyanins are antioxidants, substances found in plants that protect and repair cells from damage. Anthocyanins provide the red, blue, and purple colors found in strawberries, blueberries, and other fruits and vegetables.

The study followed more than 93,000 women for 18 years. The women, ages 25 to 42 when they joined the study, reported on their diet every four years.

A trend toward lower risk of heart attack was found in women who ate more than three servings of blueberries and strawberries weekly, compared to those who ate fewer servings. A serving is roughly half a cup.

"Substances naturally present in red/blue colored fruits and vegetables can reduce the risk of a heart attack 32% in young and middle-aged women," says Aedin Cassidy, PhD, a researcher at the University of East Anglia in the U.K.

The new findings echo those of other studies showing that a diet rich in fruits and vegetables is linked with lower heart disease, says C. Noel Bairey Merz, MD, director of the Barbra Streisand Women's Heart Center at Cedars-Sinai Heart Institute in Los Angeles.

Merz says the study is observational, meaning it does not prove that berries help with heart health. Women who eat berries may also have other healthy habits that could prevent heart attacks, she says.

Researchers chose blueberries and strawberries because they are among the most commonly eaten berries.

They divided the women into five groups based on how much of the fruits they ate. Women who ate the most berries had the greatest impact on their heart attack risk.

Cassidy and her team also looked at other factors that are known to raise heart attack risk. These included age, high blood pressure, a family history of heart attack, being overweight or obese, exercise habits, smoking, and drinking caffeine and alcohol.

Women who ate more of the fruits also reported other heart-healthy habits, such as being less likely to smoke and more likely to exercise.

Cassidy says the study focused on younger women because there is not much research on preventing heart attacks in that age group.

Although the actual drop in the number of heart attacks was small, Cassidy believes that eating anthocyanin-rich fruits and vegetables early on could pay off later, when heart attack risks rise with age.

The substances may work by improving HDL "good" cholesterol, the researchers say. They may also lessen inflammation, which is linked with heart attack risk.

Although the study focused on blueberries and strawberries, many other fruits and vegetables are rich in the anthocyanins, Cassidy says. Among them: eggplant, raspberries, black currants, plums, and cherries.

Eating more of these fruits and vegetables ''could have a have a significant effect on prevention efforts," says Cassidy.

The study is published in the journal Circulation.
