The three most dangerous bacteria are Listeria, Tuberculosis and Brucellosis.
Milk is much safer now since pasteurisation and vaccination of cattle, but people are strongly advised NOT to to use unpasteurised milk, including cheeses, and especially not for pregnant women or children.
Some cheese gourmets think the pasteurisation changes the taste of cheeses. They may be right, but is a slight change in taste worth it? I got Brucellosis in 1996, and in 2010, I am still sick.
many however they arent considered to be bad bacteria, its normal bacteria as is in yogurt and milk
You dont need to boil the milk, but if you do it, you will be more certain that kefir will not turn bad (from the bacteria found in milk).
Milk will 'turn bad' when bacteria begins to digest it. Some of these bacteria can cause sickness.
Fresh milk or liquid milk goes bad because: One- It has bacteria in it. Two- If it gets above about forty degrees the bacteria starts to ferment the milk. Three- Dried milk or powdered milk cannot support bacteria, because the lack of water denies a good reproduction place for bacteria, and thusly, the powdered milk does not go bad.
Possible to kill the 'bad' bacteria in the milk that may have formed, this will not however reverse the process of the milk being off. Possible to kill the 'bad' bacteria in the milk that may have formed, this will not however reverse the process of the milk being off.
The same bacteria that is found in milk, typically Lactobacillus acidophilus.
Milk contains bacteria. When the milk is left at room temperature, the bacteria grow and spoil or sour the milk.
If i am not mistaken, bacteria gets extracted from the milk into the pan so it is bad when you scorch it.
Lactobacillus :found in butter milk, yogurt, sour cream.
salmonella
This is because temperatures within the fridge are low and are it unsuitable for the growth of bacteria which makes milk go bad. Wherelse at room temperature the bacteria will be able to grow much faster causing the milk to go bad.
Bacteria can be helpful as it is found in foods like Yogurt and milk that can help you grow. So the answer is yes.
