Environmental Law Foundation, ELF conducted laboratory testing of food products for possible lead content.

US FDA tolerable limit for lead is 6 micro grams per day but the American Academy of Pediatrics have different statement. The academy said the there is no safe level of lead exposure. The culprit lead bioaccumulates inside the body over time. Lead exposure to children is of primary concern because rapid developing bodies absorb lead much faster.

Lead has bad effects in central nervous system and brain. Other effects includes hearing loss, learning disabilities, anemia and behavioral problems.
Lead contamination is attributed to following factors: 1) The word wide use of leaded gasoline. 2) Mining activities 3) Used of lead-based paint, and 4) Use of pesticide that contain metals. Lead is stable so it keeps on filing up as we continue to use product containing this metal.
