In an effort to boost milk production, some dairy farmers are treating cows with a genetically engineered hormone called BST. ████████ ██████ ████ ███████ ███ ███ ██ ███ ████ ██████ ███ ████ ██ ███████████ ████ ██ █████████ ██ ███████████ █████ ██ ████ ██ █████████ █████ ███ ███████ ████ ███ █ ███████ ████ ██ █████████ ███ █████ ███ ████ ██████ ██ ██ █████ ████████████ █████ ███ ████ ██ ██ █████ █████ ██ ████ ███████ █████ ███████████ ███ ██ ███████ ██ ███████ ███ ███ ████ ██ ███████ ███ █████████ ████ █████ ██ █████████ ████████ ███ ████████████
Dairy farmers use BST to boost cow milk production. Some people oppose BST because it puts cows at a higher risk of infection. A higher risk of infections leads to more frequent use of antibiotics, which could appear in milk and be harmful at high levels. Milk from BST and non-BST cows is regularly screened for antibiotics.
If BST milk is not screened, it cannot be regarded as 100% safe.
If it is safe, then the milk has been scanned.
