SOME bacteria ARE killed by freezing.
Some are actually killed by the shear pressure of the actual freezing process itself.
If you want a list you'd best find it yourself.

That quote says some MAY be killed, and then they say by the crushing effect of ice formation.
That's some, and may. Plus I think even that's bullshit.
Oh yeah, how much ice is made in your fridge where the food is stored? If that were the case it would be a freezer, wouldn't it.
Tell you what, why not come up with a single type of bacteria that will be killed off by cold. I note you took quite a time to find what you did, so I'm not going to hold my breath.
Wise up. Bacteria are almost bulletproof against anything other than heat and pH changes.
How do we preserve living cells like sperm and eggs? Oh yeah, liquid nitrogen.

Oh yeah, pays to remember that on the internet you can find pages to say black is white.
There are also a lot of people out there that don't know shit from shinola.
Here's a site that seems a bit more factual than someone just giving their opinion.

They say
"It’s a common belief that the cold temperature of ice kills bacteria. However, bacteria in ice are preserved, so to speak, until conditions are more favorable for growth. Viruses are another threat because cold does not affect them at all. Often, the cause of illnesses linked to ice is handling ice with contaminated hands or utensils. Contaminants are then on the ice, which can be further spread to beverages or foods stored on ice, such as in salad bars"

You are simply splitting hairs bil.
We are all aware,or should be,why we use fridges and freezers and that bacteria multiply much more rapidly at higher optimum temperatures,that freezing keeps our food safe for long periods,and that fridges keep it safe for shorter periods.
However if your fridge is running at 5 degrees,it's no wonder if your chicken is soon walking out the door,in which case I suggest you think about a new one, as I was learnt at school that the optimum temperature for bacteria to begin multiplying is in excess of 4 degrees.
Most fridges I've had, have been capable of going close to zero and freezing many articles, resulting in a running battle with er indoors to try and stop her altering the setting and freezing everything in sight.
I suppose another relevant factor is the constant opening and shutting of the door, as against just occasional use

No I'm not.
You said it kills off many bacteria.
I said it only slows them down.
You said in that case I obviously have no need for a fridge or freezer.
I've been here before when I used to keep koi. A whole tranche of people thought that the filter bacteria died off in the winter, which was the most utter bollocks. Trouble was they were mostly too tied in with their beliefs and so uninformed scientifically that they couldn't grasp it.
All kidding aside, I can't remember a single time I have ever heard about cold killing off bacteria. To me it's completely counter intuitive. Those little buggers are tougher than you would believe.
Heat, anything over 50C will screw most species.

If fridges and freezers are doing their business, below 4 degrees for fridges, not 5, and sensible hygiene and cooking routines are normal practice, then there is virtually no reason to be paranoid about how many of the little baskets are dead and how many are just having a siesta.

I just want to say that I'm COLD COLD COLD!!!
Living room's at it's highest temp of the day now at 15 degrees (at 11pm) that's with the calor gas heater on all day, plus an electric convector heater on for the past 4 hours - I blame the stupidly high ceilings mainly!
Anyway - I'm off to crawl under my duvet with hot water bottle inside - complete with thermal PJs and 2 pairs of socks - oh how I miss my UK flat with underfloor heating

On the contrary tonight - 18 degrees at 6.38 on Dec 6th.
Only a few days ago we had a daytime temperature of only 5 degrees.
Weird or what.

About 4º here today, and I know supersteve won´t believe it, but taking some photos on my nearest surfing beach, there were loads of surfers about. All in wet suits mind! If the surf is up, those youngsters are in, not matter how cold it is. Must be mad!

Yesterday it was 17C in the town centre according to the electronic temperature gauges, but today it was 27C! That's some increase within 24 hours.
