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
"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  "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 .
"More than 80 percent of household and industrial wastewater produced in low- and middle-income countries is left untreated, and urban agriculture needs irrigation because of its low cost, availability and nutrient content," Bougnon said.
There is an increasing number of bacteria that are multi-drug resistant to conventional antibiotics and can not be treated with current therapies. 19659002] Antibiotic resistance has led to the need for more expensive drugs that many can not afford, resulting in increased morbidity and mortality.
Between 50 and 90 percent of human and animal antibiotics are excreted as a mixture of parent drugs and metabolite forms, releasing significant amounts of active ingredient into the environment where they can persist in soil and aquatic ecosystems.
The study found evidence in the channel water samples of pathogens responsible for water-related diseases that could lead to humans being directly or indirectly exposed to these effluents that suffer from acute diarrhea, chronic gastritis and gastroenteritis
Average concentrations According to the World Health Organization, 842,000 people die from diarrhea each year because of inadequate water, sanitation and hygiene.
