On the fourth day, I started with a Teams call to show the list of research papers about Bacillus in human milk donations. From the papers, I learned that Bacillus cereus is the most common bacteria that causes milk donations to be disposed of. During the meeting, Dr. Summerville explain to me that the papers all had summaries of data and what we needed was to look for raw data so we could analyze it. She said that raw data would be a csv (comma separated values) file which I would then need to convert to excel. My assignment for the day was to look for this raw data and also to research milk banks that were for-profit instead of nonprofit and just learn how they functioned.
