“…In terms of the allowable level, the results of other researchers were within the allowable range and in accordance with our results. Beikzadeh et al (19) mentioned lead concentrations in 20 yogurt and pasteurized milk samples in Tabriz regions, Iran were in the range of 5.54 -19.34 and 6.06 -10.83 ppb, respectively, which the average of lead contents in yogurt was more than pasteurized milk. In another study by Meshref et al (27), heavy metals and trace elements (Pb, Cd, Zn, Cu, and Fe) have been determined in milk and milk products and the results showed that the range of Pb concentration was 0.044 -0.751 ppm that exceeded the maximum permissible limit.…”

Background: Milk and dairy products are the main sources of essential nutrients particularly for children. However, milk and dairy products can be contaminated with chemical hazards and contaminants which pose serious health risks for consumers. These toxic compounds are entered into the food chain through contaminated soil, water, and air and their presence even at low levels would result in metabolic disorders. Objectives: The aim of this study was to determine the level of lead in pasteurized milk and different dairy products in high-consumed brands in Tehran. Methods: A total of 38 samples (18 pasteurized milk and 20 dairy products from the most-consumed brands) were analyzed using graphite furnace atomic absorption spectroscopy for quantification of lead level. Hazard quotient (HQ) and carcinogenic risk (CR) were used to assess health risk and carcinogenic risk. Results: The results showed that the levels of lead in all pasteurized milk samples and dairy products were below the allowable limit. HQ was less than 1 in all samples and CR was in the range of 10-8 to 10-7 and both were at acceptable levels. Conclusions: It can be concluded that there was no risk of carcinogenicity in pasteurized milk samples and dairy products for children and adults. However, due to the higher consumption of milk by children and their greater susceptibility, the level of heavy metals should be monitored by health agencies.

“…One of the vital nutrients in milk and dairy products is minerals [9]. Minerals are essential for humans, and they have many physiological functions in the human body such as enzymes and hormonal structure ,and regulative [10,11]. Milk and dairy products containing major and trace elements can include contaminants such as heavy metals.…”

“…These heavy metals have toxic and some harmful effects on humans. Heavy metals ingested by humans may lead to serious health problems such as kidney failure, genetic mutations, nervous system disorders, cardiovascular problems, many types of cancers, respiratory disorders, a weak immune system, and infertility [9,11]. The heavy metals entranceways to humans can be via the consumption of dairy products and meat.…”

The Çökelek samples what 30 different, were collected from randomly local bazaars to investigate heavy metal contaminant and mineral levels and some physicochemical and microbiological properties of samples. The As was detected in the 4 of 30 samples, while the Pb was determined in the 6 of 30 samples. The mean major and trace element contents of Çökelek samples were ordered as Na > P > Ca > K > Mg and Al > Zn > Ni > Cu, respectively. The physicochemical properties indicated a high deviation among samples. The mean total solids, ash, salt, fat, protein waters soluble nitrogen contents and ripening index of samples were 29.83%, 1.88%, 0.68%, 4.31%, 19.84%, 0.33%, and 1.79%, respectively. The mean TAMB count of Çökelek samples were found as 8.26 log CFU g − 1 . The coliform bacteria and yeastmold counts were detected in 11 and 27 of 30 samples, respectively. The mean coliform and yeast-mold counts were 1.82 log CFU g − 1 and 7.11 log CFU g − 1 , respectively. There are not mentioned traditional cheeses in the legal rules such as the Turkish Food Codex. So, there is no legal limit and standard production processes. This situation is a problem in terms of traditional cheese quality. For this reason, traditional cheese should perform a further studied, and determine the legal limits.

“…After their emissions from the sources, they can be transported and deposited on the soil [ 20 , 21 ]. Hence, livestock is exposed to these elements, which enter into the trophic chain through consumption of their meat or dairy products, such as milk [ 22 ], becoming potential health risks [ 23 , 24 ].…”

Although milk and plant-based drinks are widely consumed foodstuffs with high nutritional value, their consumption may also mean intake of non-essential/toxic elements becoming a risk for human health. This study was aimed at determining the concentrations of essential (Ca, Co, K, Mg, Mn, Na, Ni and P) and non-essential/toxic (Hg, Pb, U and V) elements in milks (cow and goat), plant-based drinks (soy, almond, rice and oat) and infant formulas from organic and conventional production systems. Lactose-free, fresh and ultra-high-temperature (UHT) milks were also included. Chemical analyses were performed by means of inductively coupled plasma-mass spectrometry (ICP-MS). The content of the elements hereby assessed did not depend on the production system and the presence of lactose. However, significant differences were found in the concentrations of multiple elements when comparing sterilization methods, source (animal vs. plant-based) and animal species. Non-essential elements were not detected in milks and plant-based drinks, excepting Pb, which was detected in three samples. While the consumption of goat milk is recommended, considering the global intake of essential elements and the absence of non-essential elements, further studies should be conducted to confirm the absence of non-target toxic elements at very low trace levels. On the other hand, the best plant-based drinks are those made up with almonds (intake of Ca) and soy (K and Mg). The current results should be useful to help the population to balance the benefits and risks from milks and plant-based drinks consumption, as well as to adapt their dietary habits.
