Pharmacotherapeutic group:

Products for teats and udder, Disinfectants

ATC Vet Code: QG52A

Iodine, formulated as an iodophor, is a halogen with an oxidising biocidal action against most mastitis pathogens.

Veterinary Disinfectant: Dermatologicals:Antiseptics and disinfectants. Iodine

5.1 Pharmacodynamic properties

The active ingredient is a disinfectant with bactericidal activity against most bacteria. The post milking topical application of the product to the teats of lactating cows, sheep and goats prevents the ingress of pathogenic organisms into the streak canal of the teat and thereby aids in the prevention of the spread of mastitis from infected quarters to non-infected quarters.

5.2 Pharmacokinetic properties

Although there is some evidence that iodine may be absorbed through teat skin, most iodine in milk is from dietary sources. Iodine has been determined in milk principally as the iodide. In the UK, the Committee on Toxicity of Chemicals in Food, Consumer Products concluded that the concentrations of iodine in cows' milk are unlikely to pose a risk to health after the determination of iodine levels in milk in 1998/9.

The Committee for Veterinary Medicinal Products (CVMP) has concluded that it would be inappropriate to elaborate Maximum Residue Limits (MRLs) for iodine and that iodine should therefore be included in Annex II of Council Regulation 2377/90/EEC (CVMP, 1996; Annex E).

Silkidip is a ready to use teat dip/spray containing iodine (as an iodophor) and emollients as an aid in the prevention of the spread of mastitis in lactating dairy cattle, sheep and goats.
