Contamination of poultry farms with fluorophenicols can have devastating effects on agricultural soil ecosystems.
Recent studies by Brazilian scientists have shown that the presence of residues of these antibiotics in poultry manure can greatly reduce earthworm populations.
Among all microorganisms in the soil, earthworms are one of the most important quality characteristics. These organisms have an important role in improving the structure of organic matter and maintaining soil integrity.
Following the increase in the world population, the production of the poultry industry has increased sharply, especially in recent decades. Manure from poultry farms is widely used as agricultural fertilizer around the world due to its high nutrient content and improvement of various soil traits such as pH, water holding capacity, and organic matter.
Indeed, the use of agricultural residues for food production is one of the important goals of the United Nations Sustainable Development.
But the same nutrient fertilizer in some cases can become serious pollutants for agricultural farms.
Researchers ‘assessments suggest that fluorophenicol disrupt the earthworms’ respiratory activity, altering their DNA functions by altering antioxidant enzymes and causing stress in these organisms.
According to the results obtained in this study, it seems that the use of this valuable manure in agricultural farms should be done with specific protocols and under specific biological measures.
Earlier, many researchers had talked about the disadvantages of continuous use of poultry manure in agricultural farms and the possibility of the occurrence and presence of antibiotic resistance genes in the soil.
