Antibiotics In Manure Implicated In Human Pathogenic Bacteria In Soil

Researchers have have found that the repeated application of manure contaminated with antibiotics changes the composition of bacteria in the soil.

The focus of the investigation was on sulfadiazine (SDZ), a widely used antibiotic in animal husbandry which enters the soil via manure. The researchers report that repeated application of the antibiotic leads to a decrease in beneficial soil bacteria and at the same time an increase in bacteria that are harmful to humans.

Since antibiotics are commonly used in animal husbandry, the implications for agricultural areas that are fertilized with the manure of these animals are of great interest. The study results confirmed the scientists’ hypothesis that the application of antibiotics has an effect on the composition of soil bacteria.
