Week 11 Control Of Microbial Growth

Hi everyone,

Today’s lesson is all about how we control the growth of microbes to keep environments safe especially in healthcare, food handling, and public spaces. Microorganisms like bacteria, viruses, fungi, and protozoa are all around us. While some are beneficial, others can cause disease, spoilage, or contamination. To prevent infections and maintain hygiene, we need to reduce or eliminate harmful microbes using different physical and chemical methods. Whether it’s sterilizing surgical tools, disinfecting hospital surfaces, or washing hands properly, controlling microbial growth is a critical part of infection prevention and public health.
