If you have bought raw milk then you are not new to its unsavoury smell. This smell is characteristic in nature and you can trace it back to a certain brand of soap, a known deodorant spray, some farm chemical spray or characteristic body odour of someone you know. You are right in your weird thinking; yes, milk is a smell magnet and will hold onto any smell in its environ with amazing ease.
This peculiar characteristic calls for special treatment to ensure quality and wholesome milk production. The process of clean milk production begins with the cow, its residence, through its feed to the person milking and how milk is handled thereafter. Anything going wrong at any of these stages can impart a foreign smell to milk.
