Do all farmed salmon receive drugs and medications?
No. Many farmed salmon are never treated with any medication throughout their entire lifecycles. This is due to improvements in fish husbandry and handling that reduces stresses on the fish that can make them more susceptible to diseases. When medications are required to maintain health, they must be prescribed by a licensed veterinarian and are administered for only as long as required to treat the disease. A mandatory withdrawal period must be observed after any treatment before fish are harvested for consumption.
