Factors Affecting the Increase of Microbial Cow’s Milk Load in Farmers

Factors Affecting the Increase of Microbial Cow’s Milk Load in Farmers

Factors Affecting the Microbial Growth of Cow’s Milk in Farmers:

⭕️ Animal Trap:

A: Livestock trauma to infectious diseases such as tuberculosis, brucellosis, and so on. Also, Oram breast, which has the greatest impact on the increase in microbial load in raw milk.
B: Non-washed milk before milking: One of the important factors in increasing the microbial load of milk, especially in traditional livestock, is lactation before breastfeeding.

Removing and cleaning the hair behind the lamb around the lamb and washing the breast with lukewarm water (to clean and remove the waste and stool of the livestock) and removing it with a clean dry towel can to a large extent prevent the bacteria from penetrating into milk.
.
It is noteworthy that 1 gram of livestock stool can enter up to 40 billion bacteria.

⭕️ Milking livestock:

A: Manual:
During livestock milking (especially with the traditional method), it is important that the milk is not cleaned and can be the carrier of pathogenic and non-pathogenic microbes to raw milk.
Up to 45 million bacteria can be infused into the milk, according to a hand shower.
B: Milking machine:
The low or high suction speed of the machine can cause mastitis in the livestock. It is noteworthy that after each milking, the cattle and before sucking the suckers into another slaughter cow should be rinsed with lukewarm, non-disinfectant.

Due to the fact that the number of bacteria in the early days of milking is high, mutation in the beginning of milking must be done in both ways (one way to penetrate the bacteria into the breast through a milk spinach is at the tip of the pacifier It usually loosen when sitting on the ground or after milking, and after every lactation, it is necessary to prevent livestock from keeping the livestock for at least 20 minutes.) ?

Milking milk:

A: Milk Containers (Beadon Cube) should be completely clean. Conventional milking dishes add up to 800,000 bacteria to milk.
B: Milking machine. routes. Crabs; Jars and dipstick are completely disinfected and then rinsed with water. It should be noted that residues of disinfectants do not remain on the paths; they do not leave the mouthpiece, because it lowers the quality of milk and does not use cheese and fermented yoghurts.

Unclear milk:

The use of a cleaner or flattener on the bedding cans and softeners to a large extent prevents the penetration of the straw and the skin and the skin into the milk.

۱ liters of fat to 70 million drops of powder per day to 78 million 1 grams of straw to 10 million and one flies fell in Shereta to add 2 million bacteria to raw milk.

⭕⭕Switching milk:

Due to the high milk temperature after milking (37 degrees) and the possibility of microbial growth, it is necessary to reduce this temperature to an acceptable level (less than 8 degrees) as soon as possible. In the event of a rapid drop in milk temperature within 30 minutes after milking, the total count of milk microbes in livestock farms is reduced.

It should be noted that the temperature of the milk during cooling should not fall below zero degrees, because it causes two phases of milk and a decrease in its quality. ⛔️⛔

Delay in the cooling of the milk and the lack of proper washing of the condenser and coolant valve cause the microbial load of the milk to rise.

Maintaining a long-cooled milk for a long time and then sending it to factories (up to a maximum of 24 hours) causes the growth of cold-blooded microbes in the milk, and these bacteria, especially pseudomonads, release the proteolytic and fluid resistant polyethylene enzymes that are resistant to heat, which can corrode pasteurized products and sterilize. .

⭕️ Tankers:

According to studies, milk tankers play a significant role in raising the microbial load of milk.

Washing the tankers with disinfectant (soap liquid soap) after each milk drain and subsequent optimal watering seems to be necessary to note that in the summer, in the case of incomplete washing, in addition to raising the microbial load, according to the stomata Available on the inner surface of the tankers, there is the possibility of spawning flies, and these flies may later appear as white larvae on the surface of the milk that can be seen when young larvae are kept in the presence of young flies. It is also necessary that the sex Tankers are made of double glazed steel.

⭕️ Water used in animal husbandry:

Water used to wash dishes and appliances should have the characteristics of drinking water. In case of contamination, the microbial load of the milk increases. The contaminated water germs often make the milk thick and sticky, including bacterial bacteria from drinking water, such as Pseudomonas, Salmonella, Shigella and ….
