White House: More than 800 food, feed inspections missed during shutdown

More than 800 food and feed safety inspections were deferred during the federal government shutdown in October, the White House Office of Management and Budget (OMB) said in a report released yesterday.

The report says the Food and Drug Administration (FDA) delayed close to 500 domestic food and feed inspections during the shutdown, and another 355 inspections that were due to be conducted by states under contract with the FDA also were skipped.

"The FDA also cut back on examination, sampling, and laboratory analysis of imported products during the shutdown," the report adds, without giving any numbers.

It says the FDA continued "for cause" inspections where there was an imminent public health threat, but it does not specify how many of those were carried out.

The report doesn't discuss how the shutdown affected the Centers for Disease Control and Prevention's (CDC's) investigations of foodborne disease outbreaks. CDC officials said during the shutdown that about 9,000 of the agency's 13,000 employees were furloughed. The CDC recalled some employees to help respond to a multistate Salmonella outbreak linked to Foster Farms chicken.

NIH researchers launch genital herpes vaccine trial

The National Institutes of Health (NIH) today announced the launch of the first human trial of an investigational vaccine against genital herpes, one of the most common sexually transmitted diseases.

Currently, there is no vaccine for genital herpes, which infects about 776,000 people each year and exacts a heavy psychological and physical toll on those infected and poses a serious risk to babies born to infected mothers, the NIH said in a statement.

For the experimental vaccine, scientists removed two key proteins from herpes simplex virus type 2 (HSV-2), blocking its ability to multiply and cause genital herpes, according to the NIH. The vaccine, called HSV529, was developed by David Knipe, PhD, professor of microbiology and immunology at Harvard Medical School in Boston. Sanofi Pasteur manufactures the investigational vaccine, which has undergone 10 years of preclinical trials.

The phase 1 clinical trial involves 60 adults ages 18 to 40, including some who are already infected with HSV-1 and/or HSV-2. The trial is designed to test the vaccine's safety and immunogenicity. Researchers expect to complete it by October 2016.

News brief

Flu shows slight increases in US and its neighbors

Flu activity in the United States remained at low levels last week, though some markers showed slight increases, the US Centers for Disease Control and Prevention (CDC) said today.

The percentage of respiratory specimens that tested positive for flu rose from 4.5% to 4.9% over the past week, and the percentage of clinic visits for flu-like illness crept up from 1.2% to 1.4%. Both indicators remain below their baselines.

Of specimens there were tested, 93% were influenza A, and of the influenza A viruses that were subtyped, 2009 H1N1 isolates outnumbered H3N2. Antiviral resistance tests last week detected two isolates with resistance to oseltamivir; both were 2009 H1N1 viruses.

The CDC received two reports of pediatric flu deaths, both of which occurred during the 2012-13 season, lifting the past season's total to 169.

Two states, Alaska and Alabama, reported regional activity, while four other southern states (Mississippi, South Carolina, Texas, and Virginia) and Puerto Rico reported local activity.

Elsewhere in North America, flu activity also increased slightly in Canada, with 10 regions reporting sporadic activity, according to an update today from the Public Health Agency of Canada (PHAC). PHAC said the number of positive tests for flu rose for the second week in a row and that influenza A has been predominant, with 2009 H1N1 more common than H3N2. In Mexico, flu indicators are up slightly, according to a Nov 6 update from the Pan American Health Organization (PAHO).

In Europe, flu activity remained low, with all 25 reporting countries reporting stable or decreasing trends, according to an update today from the European Centre for Disease Prevention and Control (ECDC).

Cambodian boy hospitalized with H5N1 infection

Health officials in Cambodia have detected an H5N1 infection in a 10-year-old boy from Kampot province, the country's 24th case so far this year, Xinhua, China's state news agency, reported today.

News of the case came in a joint statement from Cambodia's health ministry and the World Health Organization (WHO), according to the report. The boy tested positive for the virus yesterday after he was admitted to Kantha Bopha Hospital in Phnom Penh. He is in critical condition and is receiving oseltamivir (Tamiflu).

An investigation into the source of his infection found that a month before he got sick, about 30 chickens died in the boy's village, and he had helped carry some of the birds for his brother, who prepared a meal from them.
