A research group led by Professor Usui of Rakuno Gakuen University has succeeded in reducing drug-resistant bacteria contained in livestock feces by using baked scallop shell powder and lime nitrogen to treat livestock feces.
The spread of drug-resistant bacteria, which are bacteria that are resistant to antibiotics, has become a major public health problem. Antibiotics are also used on animals, and drug-resistant bacteria are also found in livestock feces. Therefore, there are concerns that drug-resistant bacteria contained in livestock feces may spread into the environment through composting, and a solution to the problem has been sought.
Therefore, we focused on the fact that scallop shells, which are industrial waste, have a bactericidal effect when burned, and that lime nitrogen, which is used as fertilizer, also has a bactericidal effect, and we mixed them with livestock feces and composted them. . As a result, by adding baked scallop shell powder and lime nitrogen, we succeeded in significantly reducing drug-resistant bacteria contained in livestock feces.
If this method is used in the field, it is expected that it will not only prevent the spread of drug-resistant bacteria from farms, but also be a means to effectively utilize scallop shells, which are industrial waste.
