It is agreed upon that the job of a good teat dip is to i) quickly kill the bacteria on the teat immediately after milking, ii) provide some residual activity for as long as possible after milking, iii) be non-irritating to the teat skin and IV) maintain safety standards for consumers of milk products. As soon as one starts to make a home-made teat dip they are accepting the responsibility of putting the consumer at risk. How can a home-made teat dip be expected to satisfy the above four standards. Why are commercial teat dips more expensive? Common sense would dictate that the companies have had to invest money in research to satisfy the role which teat dips play in managing mastitis by reducing the number of new infections while maintaining the consumer confidence that food safety is a high priority on dairy farms. For example iodine teat dips are formulated using special carriers such as polyvinylpyrrolodine to form iodophors which help in the residual killing effect of bacterial, however, some free iodine is still available, this formula can not be duplicated in home-made teat dips.3 If this is attempted then one is liable to have a teat dip with a low pH of 3 to 4 which means that you would risk burning the teat ends if exact formulating methods were not used.3 Another concern in using a homemade iodine teat dip is that iodine is readily absorbed through the skin and is therefore deposited in the milk. Therefore pressure exists for the company which manufactures a teat dip because if problems develop with respect to the safety of the milk due to iodine in the milk then they are responsible. Every time a batch of teat dip is made it must be EXACT according to the formulation, can home-made teat dips ensure such formulation?
