“…Obtained values were within the range established for cow milk in Eastern Europe (9.2-1790.6 µg/l, Paulíková et al, 2008) but did not reach the normal concentration (50 µg/l, Anke et al, 1998) and optimal contribution to human supply (100-300 µg/l, Schone et al, 2009). They corresponded to the low and very low levels suggested by Mee and Rogers (1996).…”

“…Iodine was determined in all the samples with the help of kinetic rodanide-nitrite method known for its high sensitivity (detection limit in solution equaled to 1 µg/l) (Yatsimirsky, 1967, Komrakova and Lukashev, 1985, Proskuryakova and Nikitina, 1976Garwin et al, 1994;Paulíková et al, 2008). Absorbance of solutions was measured with the help of photocolorimeter FEK-56M and spectrophotometer Specord Carl Zeiss JENA.…”

“…Another factor might be the regional difference in the ratio of small and large dairy farms described by Vorlová et al (2014). Paulíková et al (2008) and Crnkić et al (2014) describe a significant difference in the iodine content in different regions of their countries. Results of this study also record regional differences in the iodine content, however, they showed significant differences (P < 0.01; P < 0.05) only in 2017 (Fig.…”

The study examines an analysis and evaluation of iodine content in raw cow’s milk in three regions of the Czech Republic between the years 2008 and 2018. Bulk milk samples were collected at dairy farms situated in South Bohemia, Central Bohemia, and the Vysočina Region. Iodine in milk was determined on the basis of alkaline ashing, using the spectrophotometric method according to Sandell-Kolthoff. The highest mean iodine content was measured in 2009 (485.5 ± 408.2 μg/l) and the lowest in 2016 (169.2 ± 71.7 μg/l). Since 2010 there has been a gradual decline of iodine concentration, from 479.5 ± 304.9 μg/l in 2010 to 231.2 ± 63.5 μg/l in 2018. A similar decreasing tendency was recorded in all the monitored regions. The percentage of samples containing iodine above 500 μg/l was on the decrease (37% in 2009; 0% in 2016–2018) and less than 80 μg/l (8% in 2009; 0% in 2017–2018). The current state corresponds to the requirements for iodine content in milk for human consumption. The study emphasizes the importance of continuous iodine content checks in milk and the related adjustments of iodine supplementation to the feeding rations of dairy cows.

“…In this regard, milk iodine concentration might be used as an indicator of iodine intake in dairy animals, when for instance the milk iodine concentration below 80 μg/l might indicate iodine deficiency in sheep (Travnicek and Kursa 2001) and 60 μg/l in goats (Paulikova et al 2008).…”

The aim of the review was to provide information about the importance of iodine in human nutrition and to review milk as an important source of iodine, and also to summarize the main factors affecting iodine concentration in milk. Iodine is an essential element for the thyroid gland function and synthesis of thyroid hormones, which regulate key processes of metabolism, brain development and growth. Therefore, it is important to ensure adequate, neither deficient nor excessive, intake of this element in animal nutrition, but more importantly in the nutrition of humans. Milk and dairy products are very valuable sources of iodine. However, its concentration in milk is very variable, as it is affected by many different factors -iodine intake in feed, antinutritional factors, iodine species (forms) used for feeding, animal keeping, farm management and possibly also milk yield. Additionally, milk iodine concentration is also affected by teat dipping with iodine disinfection, and by milk processing (e.g. skimming and heat treatment). All these aforementioned factors may possibly play its role in improving the human nutrition, especially the nutrition of pregnant, lactating women, and people on low-salt diet who are the most vulnerable to insufficient iodine intake.
