Abstract

This study investigates the impact of various storage conditions on the microbiological quality of expressed breast milk (EBM). A total of [number] samples of EBM were collected from lactating mothers and stored under different conditions: refrigeration at 4°C, freezing at -20°C, and room temperature at 25°C. Microbiological analyses were performed at different time intervals (0, 24, 48, 72 hours for room temperature; 1, 2, 3, 6 months for refrigeration; and 1, 2, 3 months for freezing) to assess bacterial growth, contamination levels, and overall microbial quality.

The study found that storage conditions significantly affect the microbiological quality of EBM. At room temperature, bacterial growth was observed within [time frame], with notable increases in contamination levels. Refrigerated samples showed a slower rate of microbial growth, with contamination levels remaining relatively stable up to [time frame]. Frozen samples maintained the highest microbiological quality, with minimal bacterial growth detected even after [time frame]. Proper storage conditions are crucial for maintaining the microbiological safety of expressed breast milk. Refrigeration and freezing are effective in preserving the quality of EBM, with freezing being the most reliable method for long-term storage. This study highlights the importance of adhering to recommended storage practices to ensure the safety and efficacy of expressed breast milk for infant consumption.
