The UK's veterinary medicines regulator (VMD) has introduced a new requirement for online sellers of veterinary medicines. Internet retailers registered in Great Britain (GB) and Northern Ireland (NI) must now display separate logos on their websites confirming their official registration. The key feature of this new requirement is that GB and NI have different logos—this reflects the differences in regulatory regimes operating in these territories following Brexit. This way, customers will be able to visually distinguish which jurisdiction an online veterinary medicine seller is registered in. The purpose of introducing the logos is to help pet owners and veterinary professionals verify the legality and reliability of an online store before purchasing medicines for pets or livestock. The presence of an official logo will serve as assurance that the retailer has passed the necessary checks and meets the regulator's requirements. The new requirement affects all online platforms selling veterinary medicines in Great Britain and Northern Ireland. Retailers will need to update their websites and display the appropriate logo depending on the region where their business is registered. Experts note that such measures are aimed at combating illegal online sales of veterinary medicines and increasing consumer confidence in legal sellers. This also helps protect animal health by reducing the risk of purchasing counterfeit or substandard medicines through unverified sources.
