“…The importance of milk consumption is widely recognized and documented, especially in the pediatric population ( Bishop MacDonald, 2010 ). Milk production and quality are affected by environmental conditions ( Zhou et al, 2019 ) and dictate the concentration of competitiveness of the dairy chain ( Ding et al, 2019 ).…”

Milk quality is affected by the concentration of lead (Pb) in soil and pasture grasses used to raise cattle, especially in areas near mining-metallurgical complexes. In this study, the Pb content of soil and its transfer to grass and dairy milk in an area located to 20 km from the La Oroya Metallurgical Complex in Peru (altitude, >3700 m s.a.l) was measured. Twenty soil samples (0–30 cm depth), 20 grass samples were collected, and 0.5 L of milk was obtained from 20 lactating cow in the communal cowshed. The Pb concentration (mg/kg) was quantified by flame atomic absorption spectrometry using a commercial Pb standard as quality control. The Pb average concentration in the soil, grass, and milk samples were 217.81 ± 39.48, 20.09 ± 2.83, and 0.58 ± 0.018 mg/kg (p < 0.01), respectively. The transfer factor (ratio of metal concentration) for Pb from soil to grass and from grass to milk was 0.095 and 0.031, respectively. The soil, grass, and milk samples all presented high Pb concentrations, with the milk samples containing 29-fold more Pb than the safety limit established by European regulations and were not suitable for human consumption or the manufacture of cheese, yogurt, and other derivatives. Our findings demonstrate that action to remediate these soils is critically needed.

International audienceCow’s milk contains bioactive secondary phenolic compounds that are formed by bovine’s gut bacterial flora from plant phenolic compounds. Equol, a metabolite of daidzein, is one such secondary compounds of biological interest. The potential of phenolic compounds in milk as dietary antioxidants and their distribution within the milk matrix were examined. The equol concentrations, total phenolic contents, and antioxidant activity (Trolox equivalent antioxidant capacity and inhibition of F2-isoprostanes formation by human neutrophils in vitro) were measured and compared in commercial cow’s milk of varying lipid contents. The Trolox equivalent antioxidant capacity and ability to inhibit F2-isoprostanes formation in vitro increased with the concentrations of phenolic compounds and equol in the milk. Equol and total phenolic compound concentrations correlated positively with the milk lipid concentrations. Separate experiments using homogenized and non-homogenized milk showed that dairy equol and phenolic compounds distributed to larger extent in the lipid fraction than in the aqueous fraction of cow’s milk. Our results showed that cow’s milk may serve as a dietary source of unique phenolic compounds, such as equol. Skimming of cow’s milk may reduce the original amount of equol and phenolic compounds and thereby diminishes the overall nutritive value and functional properties of cow’s milk
