Abstract
Iodine is a milk micronutrient whose concentration is highly variable and depends on several factors. The aim of this work was to monitor the prevailing concentration of iodine in raw goat (n = 71) and sheep (n = 68) milk from farms in the Czech Republic, to assess the variation in iodine levels and evaluate them with farming practices, herd size, breed and season. Iodine was determined by a spectrophotometric method according to Sandell-Kolthoff. The mean prevailing iodine concentration in goat and sheep milk was 249.73 and 264.21 μg/L, respectively. In addition to inter-species variability, we found statistically significant differences depending on the both sheep and goat herd size. The differences between conventional and organic farming were relatively minor and without statistical significance.
Highlights
Iodine is a milk micronutrient whose concentration is highly variable and depends on several factors
Iodine concentrations below 100 μg/l were in 11% of goat milk and in 7% of sheep milk samples
Regarding the effect of the animal breed on the iodine content of milk, we found a significant effect among breeds only in sheep milk (Table 6)
Summary
Iodine is a milk micronutrient whose concentration is highly variable and depends on several factors. There were 31 countries worldwide with iodine deficiency in 1993, according to the World Health Organization (WHO) statistics. According to the data from the Iodine Global Network, based on median urinary iodine concentrations, iodine deficiency in 2017 was seen among school-age children and adults mostly in Italy, Finland and Ukraine, whereas Israelis showed one of the worst iodine deficiencies among schoolage children and pregnant women in the world (Iodine Global Network 2017). This means that inadequate iodine supply in pregnancy occurs in approximately 30% of European countries. An insufficient supply of thyroid hormones to the developing brain cells may result in congenital neurocognitive impairment (Zimmermann 2009)
