Blood lead level (BLL), is a measure of the amount of lead in the blood. [1] [2] Lead is a toxic heavy metal and can cause neurological damage, especially among children, at any detectable level. High lead levels cause decreased vitamin D and haemoglobin synthesis as well as anemia, acute central nervous system disorders, and possibly death. [3]
The FDA guidance caps lead levels for children younger than 2 at 10 parts per billion for fruits, most vegetables, grain and meat mixtures, yogurts, custards and puddings, and single-ingredient meats.
the guidelines, titled "Action Levels for Lead in Processed Food Intended for Babies and Young Children: Guidance for Industry," it added, is the latest move to support its Closer to Zero ...
Lead poisoning interferes with the normal development of a child's brain and nervous system; therefore children are at greater risk of lead neurotoxicity than adults are. [203] In a child's developing brain, lead interferes with synapse formation in the cerebral cortex , neurochemical development (including that of neurotransmitters), and ...
The guidance titled "Action Levels for Lead in Processed Food Intended for Babies and Young Children: Guidance for Industry" is part of the FDA's Closer to Zero initiative to reduce exposure to ...
High levels of lead at this age can produce impaired neurological development that results in lifelong problems. A 1996 study showed 43% of children ages 1–5 in the Superfund area had blood lead concentrations above the threshold considered dangerous by federal standards; more recent reports show this number to be lower. [10]
Baby food labels will disclose levels of lead and other toxic heavy metals via QR codes, thanks to a California law taking effect January 1.
More specifically, optimal levels are generally close to a central tendency of the values found in the population. However, usual and optimal levels may differ substantially, most notably among vitamins and blood lipids, so these tables give limits on both standard and optimal (or target) ranges.
