The Ornamental Aquatic Trade Association has hit back at a report from an American University which claimed that people who kept tropical fish were at risk from bacterial infections and life-threatening diseases.

The study discovered a ‘disturbing’ amount of tropical fish were already resistant to antibiotics.

This meant fish being transported from foreign countries were carrying bacterial infections that cannot be treated and can spread to humans.

OATA responded by issuing the following statement:

"Humans do run the risk of picking up diseases from all sorts of activities in everyday life and we should all be encouraged to follow good hygiene practises, such as washing our hands thoroughly, to help cut down on the risk of picking these up.

"So diseases can pass from animals to humans, known as zoonoses, but it’s rare from ornamental fish and following good hygiene practises should further minimise the risk.

"And unfortunately the resistance to antibiotics is not a new issue for the aquatic industry and the indiscriminate use of these drugs without proper veterinary supervision in other countries is of real concern.

"There are big discrepancies across the world on how easily antibiotics are available over the counter which contributes to this problem. In this country, antibiotics must only be prescribed by vets who are directly supervising the treatment of the fish.

"Keeping tropical fish is a great hobby and we hope people aren’t put off this fascinating pastime. With a little careful thought, good hygiene practises and buying from reputable retailers, such as those who are members of OATA, people can enjoy their fish without great problems."

OATA's advice when handling fish is:

• Always wash your hands thoroughly after working with fish.
• Always cover open wounds with a waterproof bandage and wear rubber or plastic gloves of a suitable length.
• Do not prime water siphons by mouth.
• Do not eat, drink or smoke while working on your aquarium or pond.
• Do not wash nets and equipment in sinks intended for human use.
• Immuno-suppressed persons (infected with HIV or receiving chemotherapy) should not handle potentially infected materials.
• Wash and disinfect contaminated work surfaces regularly.
