सामान्य प्रश्न
61. What is E. coli, and why is it important for UPSC aspirants to understand it?
E. coli (Escherichia coli) is a type of bacteria that normally lives in the intestines of healthy people and animals. While most strains are harmless, some, like E. coli O157:H7, can cause severe food poisoning and waterborne diseases. Understanding E. coli is important for UPSC aspirants because it relates to public health, food safety, and environmental issues, all of which are relevant to the GS Paper 3 (Science and Technology, Environment) and GS Paper 2 (Health).
