Bacteria Growth and Temperatures

Now that our holiday dinners are mostly done, keep in mind that food storage is important.
As the temperature goes up or the time grows longer, or both, bacteria doubles – and
re-doubles, (Faster and Faster).
When they double too many times, they will inevitable destroy the flavor and quality of your food.
Bacteria Double
Every half-hour at 90 degrees F.
Every hour at 70 degrees F.
Every 2 hours at 60 degrees F.
Every 3 hours at 50 degrees F.
Every 6 hours at 40 degrees F.
Every 20 hours at 32 degrees F.
Every 60 hours at 28 degrees F.

Depends on the bacteria. Depends on their fitness.
Depends on their environment.
Basically, you lack control of the variables you would need to control in order to claim what you are claiming.0 -
That's pretty funny Dbmata. Who's fitness?! LOL
That said, I took those numbers off of a document at work (I work for a seafood company), and after looking closer at the internet out there, I see these are general numbers, and that there are varying opinions and arguments out there.
It is a known fact that growing bacteria produces toxins that can make us sick... and keeping foods colder works to reduce the rate of bacteria growth. Tada. better?0 -
So what you're saying is that if I could invent some kind of chilling machine we could keep inside the house we could slow the rate of food spoilage?
I'm on it!0 -

The data for cooks had to go to a generally undereducated populace who may or may not care, so the numbers are definitely inflated.

If it gets any colder in my kitchen, you will be able to see your breath. So i guess it's safe to keep the plate of food that i accidentally let sit out for a few hours.
I was keeping it anyway0 -
Yes one could argue that if you can see your breath in the kitchen, food will prolly last a bit longer lol0

I have NO idea what farenheit is in Celsius but don't forget you can also keep things HOT to prevent bacteria growth, if you have a bain marie just lying around your house lol0

I believe 40F in Celsius is 84 Hectares.

I'm not sure I understand the point of the post.
Not being a food microbiologist...or even wanting to know, much less remember, the different curves of food bacteria, I follow the 2 & 2 rule. People say it's unnecessary, but those same people never come up with a better rule than "smell it," which is not the way I wish to go.0 -
2&2? Not familiar.0

ah interesting.
When I was cooking we used 4 and 3. 4 hours at room temp and toss it. 3 days from purchase/prep/cook and toss it. The 4 hours was cumulative.0
