In humans, mastitis is quite common and symptoms develop rapidly. Most cases are thought to be caused by milk that is not expressed regularly and causes flu-like symptoms, fever, and swelling.
As for the calf, milk from the mastitis dam will not have a bad impact as long as it is healthy in all other respects because it will not consume too much. Infected milk is likely to have an abnormal taste that will prevent it from drinking it, and the cow will not let the calf drink from a swollen and sore place.
Dairy farmers operate in different circumstances where the incidence of mastitis may be a public health problem. You can find out more about mastitis in cow care through www.licautomation.com/products/saber-scc-somatic-cell-count/..

Mastitis is a very common problem in the dairy industry and it is not uncommon for dairy farmers to have a stock of intramammary antibiotics, a treatment that is far more risky to be given to regularly handled dairy cows.
Dairy cows are more susceptible to mastitis for a number of reasons: they risk transmitting infectious organisms through milking equipment, and their udder sphincter may be under greater pressure than beef cattle that periodically feed calves, allowing bacteria to enter more easily into in point. Dairy cows can also suffer from systemic mastitis.
The same advice for preventing mastitis applies to beef and milk: keeping udder clean is the key. For beef, that means giving birth to children in the grass if possible and avoiding muddy situations.
The incidence of mastitis will increase during wet weather when the nipples – especially in older cows or larger, clogged udders – may have more contact with bacteria in the mud.
There is also a greater risk of mastitis in cows that give birth at home in winter, simply because of greater bacterial exposure in confinement homes.
