Hi Sandy,
Iodine in meat is apparently a function of how much iodine the animals 
are fed. I use sea salt to ensure that I get enough iodine.
best wishes,
Ron

Hi Ron,
 
Which sea salt do you use? I use Celtic and it is a poor source of iodine.  
 
Regarding the "disappearing iodine test" to test iodine insufficiency, many 
factors can impact the dissapearance of the iodine including humidity.  I 
do believe topical iodine can sink into the skin and create local 
anti-inflammation.  I've used this for breast soreness, bursitis and other issues.  
Here is a good article regarding the disappearing iodine test and topical 
applications for iodine.
