University of the Philippines researchers detect high E.coli presence in urban farm vegetables
According to the scientists, animals like dogs, cats, and chickens that often roam around urban farms “raises the risk of microbial contamination in the irrigation water and soil where the vegetables grow.”

Researchers from the University of the Philippines Diliman (UPD) have discovered higher levels of E.coli bacteria present in urban farm vegetables compared to those being sold in wet markets in Metro Manila.
Scientists assessed 419 vegetable samples from three urban farms and four major wet markets in the capital region “during the peak of the pandemic to detect and quantify the presence of E. coli.”
“The group detected E. coli in 13.60% of all the samples. The presence of E.coli in the samples from urban farms was also higher than in the samples obtained from wet markets,” the UPD College of Science (CS) said in a statement.
The high levels of E.coli in the samples from urban farms could be linked to various factors, such as lack of thorough post-harvest processing.
“As observed in the urban farm sampling sites, they frequently use rainwater, pond water, and well water for irrigation, mainly for economic reasons, but this increases the risk of bacterial contamination,” said Pierangeli Vital of the UPD-CS Natural Sciences Research Institute.
