Dairy -- fluoride, bromide, iodine

[Guest guest]

Aliss posted the following comments on another group, referring to a recent research article on iodine teat dips. Once again, when we try to figure out the effects of iodine, we end up needing to take into account the other halogens -- specifically fluoride, bromide, and chlorine. Zoe

"What is also relevant here is that dairy cows on factory farm are consuming a dry commercial feed that is usually high in fluoride and bromide, and also drinking treated water with chlorine, chloramine and sometimes also fluoride, that harms their gut flora, blocks iodine and selenium uptake, and impairs digestion and immunity.

"Wanna bet they are iodine deficient???

"Cows pastured outdoors, grazing on fresh grass, need less drinking water and tend to have less mastitis. But I bet even pastured cows are iodine deficient nowadays with the pollution levels what they are."

Efficacy of two barrier iodine teat dips under natural exposure conditions. Foret C, Aguero H, Janowicz P., 2006. Abstract. "The efficacy of 2 iodine barrier teat dips was compared with a conventional iodine postmilking teat dip. The products were evaluated using a natural exposure trial on a 250-cow dairy based on the National Mastitis Council guidelines. Bacteriological samples were taken every 2 wk over 6 mo. All dips contained 1.0% available iodine and high levels of free iodine for germicidal efficacy. Barrier 1 was an experimental dip containing 14 to 20 ppm of free iodine, barrier 2 contained 8 to 14 ppm of free iodine, and the nonbarrier control contained 12 to 16 ppm of free iodine. The average free iodine for barrier 1 and barrier 2 combined was 14 ppm, which was equal to the average free iodine for the positive control. A 21% reduction of new intramammary infections (IMI) was observed for the 2 barrier dips combined when compared with the nonbarrier control. A significant reduction of 38% was observed for the clinical infection rate for barrier 1 when compared with barrier 2; however, barrier 1 did not significantly reduce the subclinical IMI when compared with barrier 2. Barrier 1 significantly reduced the combined clinical and subclinical IMI by 24% when compared with the positive control. The skin condition showed slight variation among the dips over the course of the trial, but no difference was observed at the end of the trial. Barrier 1, with the highest concentration of free iodine, gave the best efficacy results of all 3 dips." http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?db=pubmed & cmd=Retrieve & dopt=Abstract & list_uids=16702295 & query_hl=5 & itool=pubmed_docsum
