We all know that milk is a great source of nutrition. But did you know that it can also be a great source of helpful microorganisms? Recent studies have shown that milk from grass-fed cows contains higher levels of beneficial bacteria than milk from grain-fed cows. These bacteria can help improve gut health, boost immunity, and even fight against cancer cells. So next time you're at the grocery store, be sure to pick up some grass-fed milk for yourself and your family!

Raw milk contains many useful microorganisms that can help improve our gut health. These microorganisms can help break down food, synthesize vitamins, and produce enzymes that protect us from diseases. To get the most benefits from raw milk, make sure to buy it from a reputable source like FarmLokal. We only sell raw milk that comes from healthy cows and is free of antibiotics and hormones. Try raw milk today and see the difference for yourself!
Microorganisms in milk can help improve the quality of milk, increase its shelf life, and make it easier to digest. Microorganisms can also help reduce the risk of foodborne illnesses.
Four main types of microorganisms can be found in milk: Streptococci, Lactobacilli, Yeasts, and Molds. All of these have different characteristics that can provide health benefits to the consumer.
The most commonly isolated LAB in milk include: Lactobacillus, Lactococcus and Leuconostoc. The presence of psychrotrophs like Pseudomonas, Acinetobacter and Staphylococcus during cold storage are also frequent.
Lactic acid bacteria are the most common microorganisms in milk. They are responsible for the fermentation of milk and the production of lactic acid. This makes them an important part of the dairy industry. Lactic acid bacteria are also used in the manufacture of cheese and yogurt.
Lactic acid bacteria convert lactose into lactic acid, which makes milk more acidic and gives it a sour taste. Lactic acid bacteria also help to preserve milk by preventing the growth of other harmful microorganisms.
Did you know that raw milk is teeming with beneficial microorganisms? These microorganisms are essential for gut health and can even help fight off infection. That's why at FarmLokal, we only sell raw milk that has been sourced from healthy, grass-fed cows.
