[0002] Coliform bacteria, particularly Escherichia coli, is a common bacterium that normally exists in the intestines of humans and animals. Coliform bacteria belong to part of the intestinal flora, and most strains are harmless and participate in the digestive process. However, certain specific types of coliform bacteria, such as enterohemorrhagic E. coli (EHEC), can cause serious foodborne illnesses, leading to diarrhea, abdominal pain, and other more serious health problems. Detecting coliform bacteria in food and water helps identify potential sources of contamination, ensuring the safety of food and drinking water, and preventing foodborne illnesses.
