Scotland's salmon farmers look to minimise antibiotic use wherever possible and are committed to reducing usage even further.

Where antibiotics are used it is done sparingly and at lower levels than most other livestock sectors. New innovations and constantly evolving best practice means that a number of farmers are now able to be antibiotic free in their operations.

However the use of antibiotics to treat fish remains available to Scottish salmon farmers as part of a suite of veterinary prescribed medicines that enable farmers to prioritise the health and welfare of their animals.

Dr Iain Berrill of the Scottish Salmon Producers Organisation (SSPO) told us that: "The Scottish salmon sector is committed to an ambitious and low antibiotic use target of 5mg of antibiotic active substance per kg of salmon produced (0.0005%).

"Raising fish in the natural environment can lead to challenging and unpredictable biological conditions, yet antibiotic use remains very low. This is in part thanks to the use of vaccines for all of our fish, combined with good husbandry techniques as outlined in the sector's Code of Good Practice."

Testing by the Veterinary Medicines Directorate in 2019 found salmon to be the only livestock sector where no residue of medicines were found in the end product.
