Do you need to declare hitchhikers after using airport security bins?


Travelling can be fun, particularly if you’re heading off on vacation.  Perhaps a little stressful when travelling with a family, but once you get through the hurdles of security and customs it’s generally smooth sailing.  For most, security and customs is the most stressful part of the trip.  You’re stuck in lines.  You never know when you’re going to pull the dreaded “SSSS” card and get to have a complete search; body, shoes and luggage.  You’re inches behind the person in front of you and only have inches between you and the person who happens to be breathing down your back.  If you’re really lucky, the people in front of you are leaving on their honeymoon and can’t keep their hands or mouths off of each other.  While I prescribe that PDA’s are not needed at any time of the day, I particularly have no interest in observing prior to 9am in the morning...

I’ve written previous Talk Clean To Me blogs about the perils of travel and the fact that bugs can be found on everyone and anywhere.  If you want or need a refresher of how gross travelling on planes can be, you can check out I’m leaving on a jet plane and I fly, you fly we all share bugs together.   We all know that the plane itself can be a hotspot for picking up bugs, and due to the lack of hand hygiene, bathrooms, elevator buttons, hand rails etc. can be contaminated. However, have you thought about the level of contamination on one of the first items we touch at airports?  After we get our tickets, where do we line up?  Security.  What happens there?  We stand in line with 100’s of other people.  What do people have in common?  We carry or may be carrying germs.

A new study published by researchers from Finland and Britain found that half of the grey plastic airport security bins may be carrying infectious viruses.  The researchers took environmental swabs and tested them for influenza A and B viruses, respiratory syncytial virus (RSV), adenovirus, rhinovirus and coronaviruses (e.g. SARS and MERS).  Of the 90 environmental samples taken in total, 8 were from the grey bins.  While a very small sample size, 4 of the 8 were found to have respiratory viruses while none of the 42 samples taken around toilets showed any sign of the viruses. 

Similar to any commonly touched surface, this really shouldn’t be surprising.  At Toronto Pearson Airport about 1,100 flights take off per day.  If you consider that the smallest plane only carries around 14 people and the largest carries 525 people, there are a WHOLE LOT of people going through security and using the grey bins.   Where people congregate, germs are sure to be found.   It’s unrealistic to think that the bins are going to be cleaned and disinfected between uses.  An airport is not a hospital.  We can hope that they are cleaned daily, but the likelihood is that they’re only cleaned when visibly dirty.  It’s up to us to protect ourselves.  Wash your hands or use the hand sanitizer that is very likely hanging on your briefcase, your purse or laying at the bottom of your bag.

Are hand sanitizers losing their battle with bugs?


With the start of school most of us are preprogrammed to believe that summer is over.  Summer is a time of indulgence, a time to let your hair down and enjoy.  Unfortunately for some of us that means come fall our clothes may fit a bit differently than the last time we wore them!  We’ve lost the battle to the bulge.

What other battles are we loosing as we go about our daily routines?  I think we can all agree that hand sanitizers have become a staple in our lives.  They’re in our children’s lunch bags, in our purses, attached to our briefcases and probably stashed in places we’ve forgotten about.  It’s because of this rampant use of hand sanitizers that a recently published study I came across is so interesting.  Conducted by a group of researchers in Australia, Increasing tolerance of hospital Enterococcus faecium to hand-wash alcohols” is something you may want to read.

Antibiotic resistance is a well-known phenomenon.  It occurred as a result of widespread and overuse of antibiotics prescribed to patients.  With hand sanitizers moving to mainstream use within the community and not just in healthcare facilities have we potentially repeated history and will start to see resistance of pathogens of concern to hand sanitizers?  According to this study that very well may be the case.  The study investigated 139 samples of Enterococcus faecium.  The samples were subjected to different strengths of alcohol ranging from 23% to 70%. The samples had been taken over a 19 year period (1997 – 2015) and they found that samples from 2010 on were 10 times more resistant to alcohol.  Could this be in part an explanation to the increased numbers of HAIs associated with Enterococci?  The development of resistance to hand sanitizers would certainly complicate our infection control practices.  Additional measures or procedures would need to be put into place to reduce the risk of further resistance development.

Before we cry wolf, this is the first study to show such an occurrence.  While both interesting and concerning we can’t jump to conclusions.  That said, I hope that we have learned from our past mistakes and take a more serious look to determine if this truly is happening and if it’s happening on a global basis we seriously contemplate what we need to do to slow the resistant development down.  Enterococci are as we know widely resistant to multiple antibiotics.  Hand hygiene and surface disinfection is our first line of defense when it comes to infection prevention.  Alcohol is used in lower concentrations in many of the surface disinfectants we use.   We cannot afford to have our hand hygiene or surface disinfection products develop resistance or we’ll really be up the creek without a paddle!
