sophia - 04 Jun 2008 04:23 GMT Dear all,
I have heard from from shopkeepers that if you cool milk below a particular temparature for a certain period of time, it will kill all the germs in it or in other words it will have the effect of boiling the milk , which will kill the germs. How true is this statement ?

How true is this statement ? Hi Sophia,
The shopkeepers are correct. This process does kill bacteria.
Here is a very good description of the process:

Have fun and be healthy :-)

I agree with David Wright; cooling will only slow the growth of bacteria. I would guess/intuit that if you wanted to kill the bacteria by cooling, then you would have to get the temperature down so low that it would also crack the enzymes and kill the beneficial bacteria and then all of the green-health types would be complaining about that.
My rule of thumb when reading FDA material is: If they say a positive logical statement, it is most certainly true. This is why I was hoping to actually learn something useful about killing bacteria with cooling. (But they didn't say that, and I suspect that sophia was being ingenuous.) If they say that X does Y, then it is probably true. If they say a negative logical statement, particularly about a green-health type idea, then it is usually a meaningless statement. My favorite one is: "Stevia is not a sweetener" or "There is no scientific proof that stevia is safe". Of course, it is impossible to prove a negative, and for stevia or anything else to be proven to be safe, one would have to prove a negative. So, the FDA's saying that raw milk is bad for people without any redeeming qualities is just a waste of hot air.
Less than 400 people are harmed each year by raw milk (a positive logical statement, which I assume to be true), but probably 150,000,000 people drink milk in the FDA's jurisdiction. The reduction in the quality of health by drinking pasturized milk could be very slight but with 150,000,000 drinking it, pasturized milk could still be worst than raw milk. Like most perspective retarded/deranged people, the FDA sees the spectacular and misses the subtle. Someone dying from food poisoning is spectacular; noticing millions of people's health being marginally negatively impacted by pasturization is subtle.
For me, the issue is still an open question.

Of course, it is impossible to prove a negative, and for stevia or anything else to be proven to be safe, one would have to prove a negative. Never mind that it is obvious that sugar is unbelievably bad for people; I wonder how many people die from sugar each year and how many reports of even the slightest problem from the use of stevia. Anyway, so, the FDA's saying that raw milk is bad for people without any redeeming qualities is just a waste of hot air.

How true is this statement ? Not at all -- unless maybe you cooled it to the temperature of liquid helium. But ordinary cooling just slows the process of bacterial growth. Bacteria are hardy little suckers; even freezing them won't hurt many types.

1 E. coli bacteria also can spread from one surface to another, which means that bacteria on a cow's udder or on equipment can end up in milk. Pasteurization kills the bacteria, but raw milk can be a source of infection. Other foods that may become contaminated with E. coli include dry-cured sausage, salami and unpasteurized apple juice and apple cider.
2 Drink pasteurized milk, juice and cider. Any boxed or bottled juice kept at room temperature is likely to be pasteurized, even if the label doesn't say so.

Q Listeria on the Loose? I'm shocked that so much food has to be recalled because of Listeria. Where does this disease come from, and how can we avoid it? A Answer (Published 11/14/2002)
Updated on 4/4/2005
You may be surprised to hear that every year some 2,500 Americans develop listeriosis and 500 die due to this disease, which is caused by eating food contaminated with the bacteria Listeria monocytogenes, which occurs in soil and water and can cause severe diseases (i.e. septicemia, meningitis, and encephalitis). Both animal and vegetable foods can become contaminated from soil or from manure used as fertilizer. Animals can carry the organism without appearing ill. Listeria is killed by pasteurization, and should be destroyed by the heat used to cook ready-to-eat meats. However, less-than-optimal manufacturing practices can allow contamination to occur after processing.
Dr Weil has ONLY an M.D. from Harvard.

OK guys, it's time to find a little hole for your ideas.
