What would be cleaner?

[Flipperk]

Eating off the sidewalk after it has been baking in the hot sun in the middle of august for 10 hours, probably reaching about 140 degrees

or

Eating off the same sidewalk except in dead winter covered in 2 feet of snow?


Bacteria speaking...

trick question, neither

I'd go for summer.  Bacteria are very good at desaturating their membranes in order to tolerate cold, but at ~140 F proteins denature (except for thermophiles) and membranes can lose their selective permeability, i.e they are vulnerable.

Well if the sidewalk is "covered in snow", I'll eat off the snow.

[BoilerDown]

I don't thin 140 degrees is enough, so I'm going to go with the cold scenario.  You will let us know the correct answer, right?

Well if the sidewalk is "covered in snow", I'll eat off the snow.

Now that all depends on the color of said snow.

I would have to say that it depends entirely upon what it is youre eating!!!


that popsicle wouldnt be too good in the summer scenario
