Foster Farms recalls chicken linked to 621-case Salmonella outbreak

As the United States celebrated Independence Day late last week, federal officials announced that Foster Farms has recalled chicken products implicated in a Salmonella outbreak that has now reached 621 cases in 29 states.

In a late–Jul 3 notice that was reissued on Jul 4 with updated information, the US Department of Agriculture's Food Safety and Inspection Service (FSIS) said Foster Farms, of Livingston, Calif., has recalled chicken products produced in early March after the company's chicken was definitively linked to a patient in the outbreak.

This is the first direct evidence tying a Foster Farms product to an outbreak patient, though federal officials have long linked the outbreak to the company's products.

Direct evidence is not easy to obtain, the FSIS pointed out, as it entails obtaining product from a case-patient that tests positive for the outbreak Salmonella strain, plus packaging must clearly associate the item to a specific facility and production date. Also, officials must obtain documentation of shipping and distribution to trace the product to the facility.

The recall involves chicken produced from Mar 7 through Mar 13, the FSIS said. The products total more than 1 million pounds, Food Safety News (FSN) reported today.

"These products were shipped to Costco, Foodmaxx, Kroger, Safeway and other retail stores and distribution centers in Alaska, Arizona, California, Hawaii, Idaho, Kansas, Nevada, Oklahoma, Oregon, Utah, and Washington," the FSIS notice said.

In related news, the Centers for Disease Control and Prevention (CDC) reported on Jul 4 that the outbreak now totals 621 cases, up from 574 cases in the CDC's last update on May 27.

The 47 new cases are from five states: California, 39; Oregon, 3; Washington, 3; Alabama, 1; and West Virginia, 1. Of the 621 outbreak cases, 480 (77%) have been in California (see CDC map below).

Illness-onset dates in the outbreak, which is caused by a Salmonella Heidelberg strain, range from Mar 1 to Jun 15. Patient ages range from less than 1 year to 93 years, with a median of 18 years. Of 504 patients with available information, 181 (36%) were hospitalized.

Blood infections have developed in 13% of outbreak patients, compared with 5% in a typical Salmonella outbreak. There have been no deaths reported.

CDC fine-tunes polio vaccine guidance for travelers

The CDC today issued interim polio vaccination guidance for US travelers as it formalized advice it gave last month in a Health Alert Network (HAN) advisory, highlighting possible requirements for those traveling to polio-infected countries.

The CDC notes in a Morbidity and Mortality Weekly Report (MMWR) early release that the World Health Organization (WHO) has now listed four nations as "exporting wild poliovirus"—Cameroon, Equatorial Guinea, Pakistan, and Syria. Equatorial Guinea was not on that list when the Jun 2 HAN notice was posted. Those countries should "ensure" recent polio boosters among departing residents and those visiting the countries for more than 4 weeks, says the guidance.

The other six polio-infected nations—Afghanistan, Ethiopia, Iraq, Israel, Nigeria, and Somalia—should "encourage" the boosters. The CDC reminds clinicians, "All polio vaccination administration should be documented on an International Certificate of Vaccination or Prophylaxis (often referred to as the WHO 'yellow card')."

The MMWR article also details general recommendations for polio vaccination according to guidelines established in 2009 by the CDC's Advisory Committee on Immunization Practices.

Canada officials cite GSK flu vaccine plant

Canada's only flu vaccine plant, owned by London-based GSK, must respond within 30 days to unspecified problems identified by Health Canada inspectors at the Quebec City facility, according to a Canadian Press report yesterday.

Health Canada requested a plan and timeline for resolving the issues noted in the inspection report, which it presented to GSK on Jul 3.

"We have 30 days to review and respond to the findings noted in their report and we are committed to doing so by August 4, 2014," Michelle Smolenaars Hunter, communications manager for GSK Canada, said in an e-mail.

Although the specific problems at the plant were not revealed, some related to infractions raised by the US Food and Drug Administration (FDA) in a warning letter last month, the story said. Health Canada is writing a summary report of its findings and will release specifics when the report is completed.

The agency said the plant's problems don't pose an immediate risk to the public.

Study notes neurologic conditions in kids hospitalized with flu

About 15% of children hospitalized for influenza in Canada over five flu seasons had neurologic conditions, according to a study in The Pediatric Infectious Disease Journal.

The researchers analyzed data obtained by the Canadian Immunization Monitoring Program, Active (IMPACT) from 12 Canadian pediatric referral centers over five influenza seasons.

They found that of 1,991 children hospitalized for flu, 293 (14.7%) had neurologic or neurodevelopmental conditions (NNCs). Of those children, 114 did not have airway compromise or another indication for flu vaccination.

The authors conclude, "The burden of influenza infection in children with NNC, even those whose conditions do not obviously compromise respiratory function, is significant. All children with NNC should be recognized as having a high risk of complicated influenza infection and be targeted to receive influenza immunization."
