The NUT-Division of USAID endorses keeping the qualitative analysis of iodine in salt at households in order to provide a yes/not response, and which could be used to estimate coverage of the presence of iodized salt.
We also support the idea to have a quantitative determination of the content of iodine in salt, but not in a sub-sample of salt samples found at households. The important parameter to have is the average content of iodine and not the proportion of salt samples above the cut-off point of 15 ppm; the latter is more a quality control indicator. We propose that one (or two) composite samples per cluster are prepared mixing equal amounts of single salt samples requested from each household that has salt at the moment of the survey. The number of salt samples to be analyzed is going to be small, and the result equally valid as that obtained from the chemical analysis of many single samples.
