A 2021 Congressional investigation found that popular baby food brands including Gerber, Beech-Nut, and HappyBABY had 'dangerous' levels of toxic heavy metals. Internal company documents showed manufacturers were aware of contamination but routinely ignored their own internal standards and failed to test finished products. Companies sold products with arsenic levels up to 91x the FDA's limit for bottled water. The FDA's 'Closer to Zero' initiative was launched only after congressional pressure.
