Student puts breast milk in petri dish filled with bacteria—what happens next is mind-blowing

To all the breastfeeding moms out there—do you know the milk you produce for your babies can do wonders? One mind-blowing image of a science experiment proves that your breast milk has the ability to kill off harmful bacteria. See it for yourself below.

Vicky Green, a first-year bioscience student at South Devon College in Paignton, England, explored the amazing healing power of breast milk for her microbiology research project.

In her project, Green, a mom of three, prepared nine petri dishes filled with the bacteria M. Luteus. Next, she placed a disk soaked in a droplet of breast milk in the center of each dish.

The dishes were marked BmA and BmB. BmA contained breast milk from a mother nursing a 15-month-old, while the breast milk in BmB came from a mother breastfeeding a 3-year-old.

And the result?

Green shared the image of the petri dishes on Facebook, explaining the amazing results.

In the image, a clear circle has formed in between the bacteria and the breast milk. This shows that the harmful bacteria were completely killed off by the proteins in the milk.

Additionally, the circle enveloped around the droplet of breast milk also acted as a protective wall, which fended off the bacteria in the petri dish.

Green had similar results when she filled the petri dishes with other bacteria—E.coli and MRSA Super bug.

“I’m so excited!!!” Green wrote. “The future is bright, the future is breast milk.”

Green plans to extend this research using colostrum—a thick, yellowish, antibody-rich milky substance produced by mothers before birth and during the first few days after birth.

This eye-opening image, demonstrating the incredible benefits of breastfeeding, has since gone viral, garnering over 31,000 likes.

According to an article on, around 80 percent of the cells in breast milk are macrophages—a type of white blood cell that engulfs and digests foreign substances, such as bacteria, fungi, and viruses.

“Breast-fed babies are protected, in varying degrees, from a number of illnesses, including pneumonia, botulism, bronchitis, staphylococcal infections, influenza, ear infections, and German measles. Furthermore, mothers produce antibodies to whatever disease is present in their environment, making their milk custom-designed to fight the diseases their babies are exposed to as well,” the article stated.

In another 2010 study by The University of Gothenburgin, Sweden, it was found that a substance in breast milk known as HAMLET (Human Alpha-lactalbumin Made LEthal to Tumour cells), kills 40 different types of cancer cells.

With this scientific evidence, breastfeeding mothers should be feeling pretty special about themselves as they nurse their babies.
