Perchlorate Contamination in Food

A recent report by Consumer Reports has revealed concerning levels of perchlorate, a chemical commonly associated with rocket fuel and explosives, in various food products, particularly those consumed by infants and children. The advocacy group analyzed 196 samples from 63 supermarket items and 10 fast food products, finding that approximately 67% contained measurable levels of perchlorate, ranging from just over 2 parts per billion (ppb) to 79 ppb. Notably, children's foods had the highest average levels at 19.4 ppb, with baby food, fast food, and fresh produce also showing elevated amounts. The report highlights that foods packaged in plastic containers exhibited the highest perchlorate levels, averaging nearly 54 ppb, followed by those in plastic wrap and paperboard. These findings come years after perchlorate was first identified as a contaminant in food and water, with earlier studies indicating its presence in nearly 20% of supermarket samples. The Environmental Protection Agency (EPA) established a reference dose for perchlorate exposure in 2005, which has been contested by food safety experts who argue it remains unsafe. Despite none of the tested foods exceeding the EPA's limits, concerns persist, particularly for young children. Consumer Reports noted that a typical serving of certain vegetables could exceed 50% of the European Food Safety Authority's daily limit for perchlorate in toddlers. Experts recommend a varied diet to mitigate potential risks from contaminants, while also noting that fresh produce may be affected by contaminated irrigation water.
