(1) These things happen, I am confident that if we asked everyone on the forum whether event X had ever happened to them or their friends (one handshake) you could find an example of most ten sigma events.
(2) This isn't even nearly true. Pasteurization was invented with the express intentions of making milk last longer before it spoiled, and of killing disease causing microbes in milk. Louis Pastuer was not completely sure what disease could be got from milk, but it was known at that time that TB was a disease found in cattle aswell as humans. In practice TB is a normal infection in cattle similar to the common cold in severity, but some strains are extremely virulent in un vaccinated humans. Pasteurization massively reduced the incidence of TB, and scarlet fever in children, and almost entirely eliminated puerperal fever, all child-killers at that time. Raw milk can also carry, e.coli, salmonella, and diphtheria.
Pasteurization is one of the few preventative medicine techniques whose benefits are huge. Its up there with vaccination. A lot of its benefit is the fact that most diseases you can get from milk are a-symptomatic in cattle, so you would have to test literally every single cow in order to make milk "safe" without pasteurization, and you would have to do so every week or so, and even then a cow could get sick between tests. While this is "possible" it is certainly vastly more expensive.
I wasn't trying to suggest that pasteurization was invented "for" milk, only that that now ..as your post itself says..it is regarded as a way to make milk "safe" when it is presented to the general population as normally "unsafe". Your post shows to what degree this belief is held. To consider milk unsafe unless pasteurized is to consider all milking herds to be badly managed with little or no regard for cleanliness in handling the product. Undulant fever was a major concern (milk from sick cows) tb (sick cows) and the practice of pasteurizing milk was very reasonably adopted before there was any way to test the cows for such things. That is not now the case and hasn't been for well over 70 years.
Armchair Science, a British magazine of way back before WW2 had this to say:
"Pasteurization's great claim to popularity is the widespread belief, fostered by its supporters, that tuberculosis in children is caused by the harmful germs found in raw milk. Scientists have examined and tested thousands of milk samples, and experiments have been carried out on hundreds of animals in regard to this problem of disease-carrying by milk. But the one vital fact that seems to have been completely missed is that it is CLEAN, raw milk that is wanted. If this can be guaranteed, no other form of food for children can, or should, be allowed to take its place.
Dirty milk, of course, is like any other form of impure food — a definite menace. But Certified Grade A Milk, produced under Government supervision and guaranteed absolutely clean, is available practically all over the country and is the dairy-farmer's answer to the pasteurization zealots.
Recent figures published regarding the spread of tuberculosis by milk show, among other facts, that over a period of five years, during which time 70 children belonging to a special organization received a pint of raw milk daily. One case only of the disease occurred. During a similar period when pasteurized milk had been given, 14 cases were reported."

To say that milk CAN contain e coli and other pathogens is stating the obvious. What vegetable did they finally decide was responsible for the massive e coli outbreak in Europe some months ago?. A few years ago it was strawberries from California. WATER felled a whole bunch of people with e coli in Waterton when the treatment of contaminated water failed. (The point being if the water had not been contaminated it wouldn't have needed to be treated). Chicken is a MAJOR carrier of salmonella. Should we start to boil all our water at home, to pasteurize chickens, spinach and strawberries?
If diptheria is such a threat with raw milk why don't the thousands of people who drank it when growing up or who drink it in the few European countries where it is still legal to get it, have a higher incidence of diptheria, TB, etc. than the general population?
Now all dairy herds are routinely tested for such things as brucellosis and TB, and animals found to be suffering from such things are destroyed. Actually Canada and a number of other countries have declared themselves to be free of brucellosis as of some number of years ago. Pasteurization is a leftover from a time that there wasn't any other reasonable way to enforce that milk came from healthy cows, and handled correctly. That hasn't been the case for well over the lifetime of most of us.
As a side note, something that has been becoming more and more of an issue in hospitals is the question of infections. A head nurse in a major hospital told my sister to have a sign over her bed.."wash your hands before you touch me." and to enforce it. Perhaps another sign of people counting on technology to take care of the results of carelessness.
Anyway, the point I was trying to make was that a carte blanche acceptance of the government to take care of any particular segment of societal regulation isn't an especially good idea. Such a group soon develops its own momentum and needs to justify its own growth and importance. Sometimes it's far too easy to manipulate the general population into accepting regulations that are not necessarilly in the best interests of the public at large
btw...soured milk from raw milk can and is used with excellent results. Pasteurized milk cannot be used this way, it will not sour, it rots. If you want to have soured milk from pasteurized milk you have to add an acid to it.
