Is this Pure or Adulterated Turmeric ?

Turmeric occupies highest regards in the food and religious culture of india. It is used for religious rituals and is a regular food ingredient.

Metanil yellow is toxicologically classified as a Class II category by the Food and Agriculture Organization of the United Nations (Hazra et al., 2016). Metanil yellow can induce damage in heart, liver, kidneys, nervous system, gastric tissue, intestines, reproductive and excretory systems. Long-term consumption of metanil yellow causes neurotoxicity, hepatocellular carcinoma (Sarkar and Ghosh, 2012), tumor development (Sarkar, 2013), deleterious effect on gastric mucin (Sarkar and Ghosh, 2010), and lymphocytic leukemia (Sarkar and Ghosh, 2012).

The lead accumulates in the body and cannot be easily removed which indicates that it should not be consumed in the first place. Lead adversely effects the brain development and nervous system of children by damaging the granular and purkinje cell layer of brain. The neuro transmitters levels in the stratum, brain stem are effected, leading to attention deficit/ mental retardation/coma in Children.  In adults, lead increases the risk of high blood pressure and kidney damage.
