Meliloidosis is caused by Burkholderia in tropical climate, which is most common in Southeast Asia and northern Australia. People may get infected by touching contaminated soil or water, especially if there is a wound on their skin. People can also be infected by drinking contaminated water or inhaling contaminated dust or water droplets.
So if there is a bacterial infection in the fish tank, it may infect humans. In order to avoid this situation, it is necessary to maintain good hygiene habits, clean fish tanks regularly and pay attention to personal hygiene. Be careful when handling fish tank water, and avoid direct contact with water or using contaminated water.
