UP Manila detects hospital-grade ‘superbugs’ in Tondo street drinks, spurring emergency city inspections.
Antimicrobial-resistant bacteria have been detected in selected street-vended beverages in Tondo, Manila, raising concerns over food safety and the spread of harder-to-treat infections in densely populated communities, according to a study from the University of the Philippines Manila College of Public Health.
The research examined samples collected from “palamig” stalls, including beverages, water, ice, cups, and vendor palm swabs. Laboratory tests found significant bacterial contamination, with some samples containing antimicrobial-resistant bacteria carrying ESBL genes, which are linked to infections that may no longer respond effectively to commonly used antibiotics.
Breaking the limits of the lab results
Researchers also noted that all liquid samples tested exceeded allowable bacterial limits for powdered beverages and potable water.
The findings add to growing concerns over antimicrobial resistance (AMR), which health experts consider one of the major global public health threats. AMR happens when bacteria evolve resistance to antibiotics, making infections more difficult and expensive to treat.
However, the issue also highlights sanitation and infrastructure challenges. Many urban poor communities continue to face limited access to clean water, proper drainage systems, waste management services, and affordable healthcare, increasing contamination risks in everyday food and beverage preparation.
The infrastructure reality vs. the vendor livelihood
Street beverage vending remains part of the informal economy that supports household survival amid inflation and unstable income opportunities. Public health advocates say long-term solutions are not achieved through stricter food safety measures alone. Stronger sanitation systems, healthcare access, and community-level support are also needed to reduce health risks without diminishing small livelihood earners.

Minimizing food safety risks on Manila streets
If you can’t verify for yourself that a street stall uses filtered or distilled water, then stay away from open-container beverages. Use bottled or factory-sealed water or beverages that have been treated by boiling.
Wash your hands before and after cash transactions. Remember that bacteria such as the ESBL strains on vendors’ palms spread rapidly through paper currency and metal coins. Pack a personal spray bottle of 70 percent isopropyl or ethyl alcohol and carry it on your belt or dashboard. Wash your hands immediately after handling cash at public terminals before you touch your face, mouth, or personal devices.
Never buy food or cold refreshments from stalls situated directly adjacent to open, uncovered street gutters, construction diggings, or high-density traffic intersections. The dust and aerosolized mist kicked up by passing vehicles and stagnant drainage canals can easily settle into open ice chests, introducing environmental pathogens into the product regardless of how clean the vendor's initial mixing water was.
