Something in the air: disinfecting hand gels don’t help against H1N1

AFP reports the regular use of alcohol-based disinfecting hand gels authorities recommended during the swine flu pandemic has little effect on the disease’s infection rate, according to a US study.

The findings suggest that the pandemic virus A (H1N1) and similar strains may be most effectively transmitted in the air, rather than by contact with infected surfaces, the authors of the study said.

"An alcohol hand disinfectant with enhanced antiviral activity failed to significantly reduce the frequency of infection with either rhinovirus or influenza," wrote the authors of the study presented on Sunday at the Interscience Conference on Antimicrobial Agents and Chemotherapy (ICAAC) in Boston.

Participants in the study disinfected their hands roughly every three hours over ten weeks between August 25 and November 9, 2009. Of that group, 42 out of 100 contracted rhinovirus infections, compared to 51 out of 100 in the control group.

Similarly, 12 of those regularly disinfecting their hands contracted the so-called swine flu, compared to 15 in the control group.

"The hand treatment also did not significantly reduce the frequency of illnesses caused by the viruses," said the authors of the study led by Ronald Turner of the University of Virginia.

The study was financed by the Dial Corporation, which makes various care and cleaning products, including alcohol-based hand sanitiser.

Lack of food safety costly for diners, eateries; Alabama training center tries to fix errors

Here’s a common scene from many of the mom and pop restaurants I’ve visited: a towel used to sop up juice from raw hamburger meat also is used to wipe down counters.

Phyllis Fenn, a standardization officer with the Alabama Department of Public Health’s bureau of environmental services, has seen the same thing – too often.

The Montgomery Advertiser reports today the Food Safety Training Center on Atlanta Highway is an attempt both to help restaurant owners avoid bad inspections and to protect their customers’ health.

When Alabama adopted the 2005 Food Code, one provision was that at least one person in restaurants where raw foods are handled, including fast-food eateries and sushi bars, would become food safety certified. When the state adopted the code, it opted to go with a lead-in time — Jan. 1 of this year.

The classes can help restaurants improve their health department inspection scores, which is exactly what they are designed to do, Fenn said.

She said the certification class helps restaurants reduce food-related illnesses as well as teaching them about the proper temperatures to cook and hold food (the temperature of food that sits out at a buffet) and proper hygiene.
 

Funnel cake, fireworks and Salmonella – 4th of July celebration Parkville-style











Gonzalo Erdozain, like Nicolas Cage in the movie, The Family Man, likes his funnel cake. He writes,

 

This year, my wife and I spent July 4 in Parkville, Missouri. On Sunday, I found hand sanitizer at a pizza restaurant. Yes, exactly as shown, left, on a tray with grated cheese, salt, pepper, sweeteners and hand sanitizer.

 

I used it, but I should have taken it with me, because what I saw next could have definitely used some hand sanitizing action. Enticed by the pouring rain, frogs started appearing all over the place.

 

As expected, kids chased and grabbed them – bad idea, reptiles and amphibians are known for carrying Salmonella in their skin – and some adults screamed and cried. But the guy that gets the prize for “Worst Idea Ever” was the guy manhandling the frog – in an attempt to keep it away from a crying lady – and then eating funnel cake with those same hands.

Is there an app for hand sanitizer? Demo iPads at New York Apple stores crawling with bacteria

The N.Y Daily News reports in another pop science study that of four iPads that were swabbed in two stores last month and then tested in a lab, two contained harmful pathogens.

One sample, collected at the 14th St. store, contained Staphylococcus aureus, the most common cause of staph infections, which can lead to an array of ailments, from minor skin infection to meningitis.

The second swab from that store only contained benign, skin-borne microbes, but in unusually high quantities, pointing to an extremely grimy iPad.

Dr. Philip Tierno, director of Clinical Microbiology and Immunology at New York University Langone Medical Center, said that iPads handled by a multitude of strangers are bacteria breeding grounds.

"We clean our products and our stores regularly throughout the day," said Apple spokeswoman Amy Bessette. "And we are committed to creating a healthy environment for our customers."

Tierno said exactly what bites-l news guru Gonzalo ‘Gonzo’ Erdozain said in April after visiting an Apple store in Kansas City: Apple should consider providing small disinfecting wipes to customers and installing small sinks or sanitizing gel dispensers inside its stores.

Nine-year-old proves what ads won’t admit – sanitizers sorta suck

A fourth-grade student in Olympia, Washington has won her local science fair by demonstrating that hand sanitizers suck at killing E. coli.

Nine-year-old Celia Vernon won her class science fair at Roosevelt Elementary with an experiment involving a live sample of E. coli. Under the guidance of her father, a biologist with a background in microbiology, Vernon tested several solutions on E.coli, including Purell brand hand sanitizer.

In a side-by-side comparison with common bleach, the E.coli on the Purell side survived. On the bleach side, it died.

The Vernons say they have no bone to pick with Purell, but were surprised to learn it doesn’t kill one of the main dangers associated with exposures from using bathrooms.

A spokesperson for the makers of Purell told KING 5 News that it stands by its claims to kill 99 percent of germs and suggested we contact the Centers for Disease Control and Prevention. A CDC spokesperson says they have not studied hand sanitizers specifically on E.coli and recommend hand sanitizers only when soap and water are not available.

I know 99 per cent sounds cool, but considering the volume of bacteria out there, it don’t mean squat.

Are children really drinking alcohol-based sanitizers?

It’s not just prisoners drinking alcohol-based hand sanitizers for a buzz.

The Irish National Poisons Information Centre (NPIC) received 54 enquiries about alcohol-based sanitizers in 2009 and 74 per cent related to children. In 2008, there were just 20 calls from concerned doctors who were treating patients who had ingested alcohol hand gel

iPad or petting zoo, which one is safer?

Gonzalo ‘Gonzo’ Erdozain writes:

As an avid user of Apple products, I made my way to the Apple store in Kansas City’s Country Club Plaza on Saturday to try out the iPad.

The iPad is a touchscreen-based device, with no buttons or physical keyboards. As a budding food safety geek, I noticed all the products in the Apple store were touched by thousands of people of all ages every day, and not once did I see hand sanitizers inside the store.

I had just visited a small petting zoo near the area where I had lunch. The petting zoo had a hand-sanitizing station at the exit point, which consisted of many bottles of hand sanitizer, but no water and soap to actually wash your hands – so it wasn’t optimal, but still better than nothing at all.

If I had gone to that petting zoo, and didn’t know much about hygiene or just didn’t care, I could have brought all those germs and maybe zoonoses back with me to the Apple store, rub them good on those brand new iPads and lovely miscellaneous products and then gone home. And so the next person that came to the store with the same curiosity and excitement may have gotten my lovely zoonotic gifts.

To the Apple store manager, please, for events this big, some hand sanitizer would probably be a good idea – not just sanitizing the products at the end of the day.

A journey through the past – Wales edition

At the Dallas airport on Jan. 1, 2010, Amy ordered a hamburger while awaiting our flight to London’s Heathrow airport.

“How would you like that done?”

“160F please”

“Does that mean medium-well?”

Sigh.

We booked an airport hotel for one night to recover from the trip – and to learn to drive on the wrong side of the road, with a stickshift on the wrong side of the steering wheel, and negotiate the many, many roundabouts.

We ate dinner in the hotel bar where the only thing on the tele seemed to be … darts.

Next it was off to Oxford where we spent a quite lovely day and night with a colleague of Amy’s and her husband (above, right). Dinner was baked wild haddock with parsnips, carrots and other roasted veggies.

Today, we travelled to Newport, Wales, where many of the Powell’s hail from, including my father, grandfather, and others. We visited with a spry 80-year-old Keith Powell (below, left), a son of my grandfather’s brother, and dined at a carvery – a pub offering British fare of turkey, ham or beef carved from an intact bird or roast and served with unlimited roast veggies and other sides. While the food safety possibilities exist with carveries, this one was well-maintained and under the watchful eye of the carverer. Sorenne must have been starving as she gobbled up turkey, and when I refused a bowl for fear Sorenne would throw it at Keith or elsewhere, he asked as I put the meat directly on the high-chair table, “Are you sure that thing’s clean?”

Must run in the family. When I returned the table-top, the first thing a server did was wipe it down with a cloth soaked in sanitary solution.

Tomorrow, Cardiff.
 

Shopping cart sanitation (and don’t let kids lick packages of raw meat)

Amy, Sorenne and I go grocery shopping fairly frequently. The 11-month-old is curious about everything, a trait I called the day she was born; she’s alert, curious and increasingly mischievous.

When she was strong and co-ordinated enough to sit on her with a seatbelt on the seat behind the handle, a battle of wills soon emerged as Sorenne would have her hands on the handle, then in her mouth, or worse, would try to suckle the handle.

At this point I become much more rigorous and consistent about using those sanitary wipes  to wipe down the shopping cart seat and handle.

In 2004, clear displays promoting shopping cart sanitation were novel. And this one from Phoenix (upper right) is far more dramatic and attention-grabbing than a small container nailed to a bleak wall beside the shopping carts, which is still the norm today.

But things are changing.

Last year, USA Today reported that supermarkets and other retailers that provide shopping carts are increasingly looking to limit germ exposure for customers and their families.???, making sanitary wipes more readily available and in some cases, installing a whole cart cleaning system like this one in Wisconsin (photo by Peter J. Zuzga, for USA TODAY)

The trend continues to grow. Newspuller Gonzalo was in the Manhattan (Kansas) Target store recently and snapped these shots (below).

Parents and caregivers also have to think like the bad bug: like, don’t give the kids packages of raw meat to play with or leave within reach. Olga Henao, an epidemiologist for the U.S. Centers for disease control told USA Today last year that doing so triples the chance they may contract salmonella and quadruples it for campylobacter.
