And don't get me started on how I got E.Coli/Salmonella from the meal on my last trip... that was a fun couple of days.
It's fun, yes. But Heaven forbid really that you do not pick up
e.coli's more nefarious bigger brother, ESBL (extended-spectrum ßeta-lactamase e.coli) — in many specific cases, a high-mortality superbug (that has learnt to evade antibiotics and penicillins by stealth and re-invention) that is widespread on planes (toilets, basins, arm-rests...pretty much everything). And I have history: had ESBL sepsis in 2021, putting me on a ventilator with line-of-last-resort carbapenamase treatment, ongoing for a very long, tedious and stressful 6 weeks.
So salmonella,
e.coli... (aka 'Bali Belly'), just another day.
On my weekly commuting trips MEL-BNE-RTN, I assiduously swab down my seat and arm-rests/contact points with antiseptic wipes, even the toilet handle and anything else I am touch.
One bitten, twice shy...
Film through airport CT scanners, as a subject, is passé.
I never worry about it, I don't make a fuss; just put the film out in front of Security and let them scrutinise it, open it, swab it ... they will make the decision what happens, not you. And colourful labels won't necessarily speed up the process. Oft-times my film gets visibly passed (eyed by one person to the next in Security) around the CT, other times (3x) RVP50 goes through 3-4x with nowt to speak of. End of day, I am more concerned about health threats on generally filthy planes and transit points.
