What are the milk-borne diseases?

Epidemics of the following diseases definitely have been proved to have originated from the drinking of milk: Brucella infection (undulant or Malta fever), diphtheria, foot and mouth disease, scarlet fever, septic or streptococcic sore throat, tuberculosis and typhoid and paratyphoid A and B fever.

What is the most common source of bacteria in milk?

Bacterial contamination of raw milk can generally occur from three main sources; within the udder, outside the udder, and from the surface of equipment used for milk handling and storage.

Which type of bacteria can be found in dairy?

LAB’s commonly found in dairy products include strains of Streptococcus, Lactococcus, Lactobacilli, Bifidobacteria, Enterococcus, and Pediococci. Within these species there are numerous strain types which can be used in fermentation processes to give specific acidification and flavor profiles to the final product.

Which type of milk causes more outbreaks Why?

Raw milk was much more likely to be linked to outbreaks than pasteurized milk. From 1993 through 2006, 121 outbreaks were linked to dairy products identified as pasteurized or unpasteurized (raw). These outbreaks resulted in 4,413 illnesses, 239 hospitalizations, and 3 deaths.

Is tuberculosis a milk-borne disease?

Milk consumed raw is the principal vehicle for the transfer of tubercle bacilli from animals to man, but airborne infection does occur [3,4]. Infected milch cows are most frequent source of the tubercle bacillus, whether Buffaloes, Goats, Sheep, Camels and other ruminants may cause infection.

How is milk contaminated?

Milk may become contaminated with bacteria during or after milking. Some disease causing organisms (pathogens) can be shed through cow feces and may contaminate the outside of the udder and teats, the farm environment (bedding, for example) and the milking equipment.

What causes high bacteria in milk?

The health and hygiene of the cow, the environment in which the cow is housed and milked, and the procedures used in cleaning and sanitizing the milking and storage equipment are all key in influencing the level of microbial contamination of raw milk.

Does milk have active cultures?

One of the easiest ways to get probiotics is to use this kind of milk, which has been fermented with bacteria. You may see it labeled as sweet acidophilus milk. Buttermilk, too, is rich in probiotics.

What does bacteria do to milk?

When Lactococcus lactis is added to milk, the bacterium uses enzymes to produce energy (ATP) from lactose. The byproduct of ATP production is lactic acid. The lactic acid curdles the milk that then separates to form curds, which are used to produce cheese and whey.

Can milk cause bacterial infections?

Raw milk can carry dangerous bacteria such as Salmonella, E. coli, Listeria, Campylobacter, and others that cause foodborne illness, often called “food poisoning.” These bacteria can seriously injure the health of anyone who drinks raw milk or eats products made from raw milk.

Why does milk have a high potential to transmit?

How Does Cow’s Milk Get Contaminated? Just like all people carry microbes, all animals do as well. Sometimes the microbes that cows carry can be a problem. Dairy processing facilities have many routes for the entry of contaminating microbes.
