Indian street food is notoriously unsanitary, so why aren't locals concerned? And why do no Indian food brands seem to reach the global stage? Exposed to complex microbes from childhood, locals develop gut immunity to common bacterial strains like E. coli. In contrast, tourists lack this adapted gut flora, leaving them vulnerable to severe gastrointestinal distress, commonly known as "Delhi Belly."
Furthermore, while preparation hygiene—such as bare-hand handling and unverified water sources—remains a major concern, most Indian street snacks undergo deep-frying, high-heat boiling, or prolonged curry simmering. These high temperatures kill off the majority of pathogens, significantly reducing the incidence of acute food poisoning.
