Refrigerate After Opening

Via twitter: Wired reports on a company that's making beer from Eocene yeast recovered from amber.

Lambert and Cano had toyed with the idea for 12 years. Before Ambergene went under, the company made a batch on a lark. "We called it Jurassic Amber Ale or T-Rex Lager or something, and it was pretty good," Cano says. It was served at his daughter's wedding, and they even sent some to the Jurassic Park 2 cast party. That experiment had Cano and Lambert itching to release a beverage commercially. But they wanted it to be something respectable.

Needless to say, PlagueBlog recommends against eating anything that's over 40 million years old. In fact, only under the most extraordinary circumstances should you eat anything over 4 years old.

Fido Fricassee

ProMED-mail reports five recent cases of trichinosis "due to consumption of stray dog meat," with a total of nine cases this year.

PlagueBlog recommends against eating housepets, and especially not strays. You don't know where they've been.

Rabid Foxes

Via an unnamed source: WBZ reported a rabid fox attack Tuesday in Worcester. The victim was a 76-year-old woman who'd been gardening. The good Samaritan who held off the fox until the police shot him was also bitten. The fox was apparently known to police:

They believe this was the same fox that had been seen in the neighborhood the night before. One man was bitten, and two cats were also attacked.

There was a similar fox showdown in Pennsylvania in May.

More Recalls

Via an unnamed source: WBZ reports that Dunkin Donuts is temporarily cutting off the Dunkaccinos due to salmonella contamination at their chocolate supplier.

Via twitter: the AP reports that Shaws, Star, and Big Y are recalling some tuna steaks sold last week due to histamine.

Symptoms may include tingling or burning sensation in the mouth, rash on the face and upper body, hives and itching of skin, nausea, vomiting or diarrhea.

Don't Flu Party

Via an unnamed source: British doctors feel the need to warn people against holding flu parties. Flu partiers want immunity while the virus is still mild, but doctors there are instead trying to contain the outbreak.

Update (July 1st): Schott's Vocab also covers "vigilante vaccination."

Where's the beef?

I went to see Food, Inc. with my unnamed sources last week, and one of them has already found a topical CNN report of yet another E. coli recall.

The beef products were produced on April 21 and were distributed nationally and internationally, the USDA said. Boxes of the recalled product bear the establishment number "EST. 969" inside the USDA mark of inspection, the identifying package date of "042109" and a time stamp ranging from "0618" to "1130," the statement said.
It added that some of the beef products might have undergone further processing and might not have the "EST. 969" marking on products for sale directly to consumers.
The USDA urged customers with concerns to contact their point of purchase of the beef products.

In other words, God only knows whether the smoking beef is in your freezer right now.

E. coli Cookie Update

Thanks to an unknown source for yesterday's CDC update to the E. coli cookie dough situation:

As of Monday, June 22, 2009, 70 persons infected with a strain of E. coli O157:H7 with a particular DNA fingerprint have been reported from 30 states. Of these, 41 have been confirmed by an advanced DNA test as having the outbreak strain; these confirmatory test results are pending on the others. The number of ill persons identified in each state is as follows: Arizona (2), California (3), Colorado (5), Connecticut (1), Delaware (1), Georgia (1), Hawaii (1), Iowa (2), Illinois (5), Kentucky (3), Massachusetts (4), Maryland (2), Maine (3), Minnesota (6), Missouri (2), Montana (1), North Carolina (2), New Hampshire (2), New Jersey (1), Nevada (2), Ohio (3), Oklahoma (1), Oregon (1), Pennsylvania (2), South Carolina (1), Texas (3), Utah (2), Virginia (2), Washington (5), and Wisconsin (1).

As advised by the CDC, PlagueBlog reminds you that you should not eat raw food products that are intended for cooking or baking before consumption, no matter how yummy they may appear.

The Pandemic in Boston

Declared a pandemic on Thursday, swine flu has already claimed its first casualty outside the Americas and its first death in Massachusetts.

On the bright side, at least we aren't warehousing the ill in a tent camp on Summit Hill...yet. (Massachusetts news via Universal Hub.)

Flu Mask

The Smoking Bat

Via ProMED-mail: SciDev.Net reports on a study tracing the 2007 Ebola outbreak in the Congo to the consumption of fruit bats.

For the new study, researchers led by Eric Leroy from the International Centre for Medical Research in Franceville, Gabon, interviewed locals about the background of the Ebola cases. They were told that the annual migration of the fruit bat Hypsignathus monstrosus was particularly large in 2007.
Bats are an important source of protein in the area as wild animals are in short supply. They are often shot and then sold covered in blood.
The researchers believe the source of the 2007 outbreak was a man who bought bats at market. He survived, experiencing only a low fever, but his four-year-old daughter died after developing a sudden fever accompanied by vomiting. A family friend who prepared the girl's body for burial was subsequently infected and went on to infect 11 members of her family, all of whom died.

Swine Flu VII: Already a Pandemic

Via ProMED-mail: Bloomberg.com reports that novel influenza A (H1N1) has already met the WHO's vacillating standards for a flu pandemic, and has also been vastly underreported.

One in 20 cases is being officially reported in the U.S., meaning more than 100,000 people have probably been infected nationwide with the new H1N1 flu strain, according to the Centers for Disease Control and Prevention. In the U.K., the virus may be 300 times more widespread than health authorities have said, the Independent on Sunday reported yesterday.

Most disturbing are the prospects for ongoing summer transmission:

“While we are seeing activities decline in some areas, we should expect to see more cases, more hospitalizations and perhaps more deaths over the weeks ahead and possibly into the summer,” Anne Schuchat, CDC’s interim deputy director for science and public health program, told reporters on a May 22 conference call.

Popcorn Lung Update

"Diacetyl, the chemical that makes food taste like artificial butter flavor" [The Pump Handle] is back in the news, with a not-so-open-to-the-public OSHA meeting of the SBREFA panel. The future of diacetyl use in the food industry remains unclear.

Wikipedia has more on Bronchiolitis obliterans or popcorn lung. The tale of the single civilian victim appeared previously on PlagueBlog. (PlagueBlog recommends against eating your weight in artificially-flavored popcorn in any given year.)

Vaccinia: An Adverse Event

Via ProMED-mail: the CDC reports* on an adverse event following military smallpox vaccination. The patient survived, though the linked report may cause the reader to doubt that he would, or would want to.

Progressive vaccinia (PV), previously known as vaccinia necrosum, vaccinia gangrenosum, or disseminated vaccinia, is a rare, often fatal adverse event after vaccination with smallpox vaccine, which is made from live vaccinia virus (1). During recent vaccination programs potential cases of PV were investigated, but none met standard case definitions (2). PV has not been confirmed to have occurred in the United States since 1987 (3). On March 2, 2009, a U.S. Navy Hospital contacted the Poxvirus Program at CDC to report a possible case of PV in a male military smallpox vaccinee. The service member had been newly diagnosed with acute mylegenous leukemia M0 (AML M0). During evaluation for a chemotherapy-induced neutropenic fever, he was found to have an expanding and nonhealing painless vaccination site 6.5 weeks after receipt of smallpox vaccine. Clinical and laboratory investigation confirmed that the vaccinee met the Brighton Collaboration and CDC adverse event surveillance guideline case definition for PV (4,5). This report summarizes the patient's protracted clinical course and the military and civilian interagency governmental, academic, and industry public health contributions to his complex medical management. The quantities of investigational and licensed therapeutics and diagnostics used were greater than anticipated based on existing smallpox preparedness plans. To support future public health needs adequately, the estimated national supply of therapeutics and diagnostic resources required to care for smallpox vaccine adverse events should be reevaluated.

Rabies Pandemic Brewing in Arizona

Via ProMED-mail: National Geographic reports on a more virulent strain of rabies brewing in Arizona.

Evolving faster than any other new rabies virus on record, a northern-Arizona rabies strain has mutated to become contagious among skunks and now foxes, experts believe.
The strain looks to be spreading fast, commanding attention from disease researchers across the United States.
It's not so unusual for rabid animals to attack people on hiking trails and in driveways, or even in a bar—as happened March 27, when an addled bobcat chased pool players around the billiards table at the Chaparral in Cottonwood.
Nor is it odd that rabid skunks and foxes are testing positive for a contagious rabies strain commonly associated with big brown bats.
What is unusual is that the strain appears to have mutated so that foxes and skunks are now able to pass the virus on to their kin—not just through biting and scratching but through simple socializing, as humans might spread a flu.
Usually the secondary species—in this case, a skunk or fox bitten by a bat—is a dead-end host. The infected animal may become disoriented and even die but is usually unable to spread the virus, except through violent attacks.

Swine Flu VI: A Vaccine

Via ProMED-mail: as this flu season draws to a messy end, Scientific American blogs about the prospects for a swine flu (Influenza A H1N1 etc.) vaccine for next season. Reuters reports that the WHO is optimistic about such a shift, although it is unclear what impact swine flu will have on regular seasonal flu vaccine production.

Marie-Paule Kieny, WHO director of the initiative for vaccine research, said the agency is discussing with drug companies whether and when to stop making seasonal flu vaccine production and shift to making one for the new H1N1 strain.

Swine Flu V: Sequence Analysis

Via ProMED-mail: sequence analysis indicates that swine flu may be entirely domestic and porcine, despite previous reports linking it to human and bird flus as well as Asian swine flu strains.

"...the NA and M genes are most closely related to corresponding genes from influenza viruses isolated in swine population in Eurasia."
However, the NA and M genes from 2 swine virus isolates from America are also closely related to the novel H1N1 virus (A/swine/Virginia/670/1987, A/swine/Virginia/67a/1987), if a reasonable nucleotide substitution rate is accepted. Thus, H1N1 from Mexico may be a swine flu virus strain of entirely American origin, possibly even of relatively ancient origin.

Swine Flu IV: The Return of the Typhoid Traveller

Via Healthmap on Twitter: ABC Australia reports on the search for fellow passengers of three New Zealander students with swine flu.

There are more updates on the pig farming connection, Israel's cases, Connecticut's suspected cases, and California's deaths and state of emergency in my twitter feed.

Swine Flu III: Mexico Timeline

Via Effect Measure by way of The Pump Handle: the blog Biosurveillance reports on Veratect's extensive timeline of swine flu in Mexico, starting with an incident in Canada on March 30th.

At Veratect, we operate two operations centers based in the United States (one in the Washington, DC area and one in Seattle, WA) that provide animal and human infectious disease event detection and tracking globally. Both operations centers are organizationally modeled after our National Weather Service using a distinct methodology inspired by the natural disaster and meteorology communities. Our analysts handle information in the native vernacular language and have been thoroughly trained in their discipline, which include cultural-specific interpretation of the information.
[...]
March 30
Veratect reported that a 47-year-old city attorney for Cornwall was hospitalized in a coma at Ottawa General Hospital following a recent trip to Mexico. Family members reported the individual voluntarily reported to the hospital after gradually feeling ill upon returning from his trip on 22 March.

Of special note are the pig farming connection on April 6th, the Semana Santa [Holy Week] connection under the heading "Large mass gatherings", and Veratect's new Twitter feed.

Swine Flu II

Although no pigs have become ill and no patients have reported contact with pigs, the new swine/avian/human influenza mix coming out of Mexico has been dubbed "swine flu." Since Mexican health officials first admitted the problem on Thursday, swine flu has been detected in California, Texas, Kansas, New York City, and Nova Scotia. Suspected cases are currently under investigation in British Columbia, France, Spain, Israel, and New Zealand, mainly in tourists returning from Mexico. No fatalities have been reported outside of Mexico (where the case count now stands at approximately 1500 with over 80 fatalities).

The Associated Press reports that the WHO has declared the outbreak in North America to be a "public health emergency" with "pandemic potential."

The CDC has a page up summarizing the current investigation.

A ProMED poster notes that like this one, the Spanish Flu first appeared at the end of the flu season, but came back with a vengeance for the next one:

The 1st cases of that agent showed up in May 1918 in an army base in Kansas -- it went quiet over the summer -- and started ravaging the globe in early fall that year.

Also, someone is maintaining a Google map of the outbreak.

Swine-Bird Flu

Via an unnamed source: The BBC reports on a rash of deaths in Mexico from a new strain of flu with both swine and bird elements.

Fifty-seven people had died in Mexico City from flu-like symptoms, [WHO spokeswoman Fadela Chaib] said, and another three in San Luis Potosi in central Mexico. There are around 800 suspected cases, she said.
Health Minister Jose Angel Cordova said the virus had "mutated from pigs and then at some point was transmitted to humans".
The strain of flu had been confirmed in at least 16 deaths, with 44 others being tested, the government said.
It urged people to take preventative measures such as not shaking hands or sharing crockery.
In the US, experts say the seven people who fell ill across two states were suffering from a new form of swine flu that combined pig, bird and human viruses.
"This is the first time that we've seen an avian strain, two swine strains and a human strain," Dave Daigle, a spokesman for the CDC, told AFP.
The CDC said none of the seven victims had been in contact with pigs, which is how people usually catch swine flu.
