Misuse of drugs for “protection” rather than for disease control has far reaching consequences than we might know. You might end up with drug resistance by the bugs in your pond/aquaria. You won’t have anymore effective drugs to use.
What of using antibiotics? The bugs can transfer resistance genes to human bugs, becoming “super bugs”!
The questions for investigation… Does antibiotic resistance occur in veterinary medicine as much as, and in the same ways as, in human medicine? How do online pharmacies impact on this? How can we work together to curb this issue?
