When you make your seat selection
Note the coffee-colored stains,
Which were found, upon inspection,
To contain resistant strains—
A bacterial infection
Which the Transit man explains
Is a function of the fabric
That’s a feature of these trains.

You could start your own collection
Of the stuff beneath the seats
Crumbs of crackers or confections
Little scraps of luncheon meats
It’s a sample of perfection,
What a hungry microbe eats
In a perfect little petri dish
That runs beneath the streets

For the customers’ protection
Every night they try to clean,
And to figure a correction
For the problems that are seen
But keep up with your injections
Of all relevant vaccines
Cos these buggers are resistant
And they’re cunning, and they’re mean

One of the features of the Bay Area Rapid Transit system is the (comparatively) luxurious, wide fabric seats. But this feature has a bug–potentially, a superbug. Swabs taken from BART seat cushions have tested positive for all kinds of nasty creatures, including (subject to further testing) MRSA–methicillin resistant staphylococcus aureus.

BART are working on the problem, and are keeping the public informed.
