Irrigation of plants with wastewater can spread diseases: study



Researchers have unknowingly helped farmers spread diseases such as gastroenteritis and diarrhea by watering plants with wastewater.

Researchers from the University of Birmingham in the UK found that wastewater from canals for urban agriculture in Burkina Faso was rich in virulent human pathogens that cause gastroenteritis and diarrhea – a major cause of death in low- and middle-income countries.

They studied wastewater samples from three canals in the capital Ouagadougou – a city with 2.2 million inhabitants.

Following the identification of a wide range of antibiotic resistance genes in the water, they concluded that wastewater is used in urban urban agriculture, posing a high risk of bacterial and antimicrobial resistance in humans and animals.

According to United Nations estimates, urban urbanization in sub-Saharan Africa will increase urban livestock from 400 million in 201

0 to 1.26 billion in 2050, and cities will be recognized as an important way to contribute to food security and sustainable development To alleviate poverty.

"The use of wastewater for agricultural irrigation poses a very serious health risk, not least because it increases exposure to fecal pathogens" For antibiotic-resistant bacteria in Burkina Faso, "said Laura Piddock of the University of Birmingham, UK [19659002] "We urgently need further research to determine the extent to which exposed populations are affected by this health problem," said Piddock.

"It is also imperative to have global access to clean water, sanitation and hygiene in low and high-income countries Improving bacterial resistance spreads from the environment to humans, she said.

"It is reported that 200 million city dwellers worldwide work in urban agriculture and in some cases up to 90 percent of demand after cities produce verderbl vegetables, according to UN research, "said Blaise Bougnon of the University of Yaounde in Cameroon
