Does popcorn in cinemas and supermarkets contain lead?

Many post-70s and post-80s people may still remember that the popcorn machine was baked like a "black gourd" on the street stove, and with a bang, fresh popcorn came out. However, a few years ago, it was revealed that the special processing technology of barrel popcorn machine would lead to lead in popcorn, so this old popcorn machine gradually withdrew from the market.

Recently, however, some people suspect that popcorn sold in supermarkets and cinemas also contains lead. Is it true?/You don't say. CCTV reporters bought six kinds of popcorn in cinemas and supermarkets respectively, and then sent popcorn samples to food testing stations for heavy metal lead detection. After sampling and testing, the inspector found that four of the six popcorn samples contained lead. Among them, the highest content of lead in popcorn was 0.042 mg/kg, and the lowest was 0.0 18 mg/kg, while the other two kinds of popcorn were not detected. It seems true that popcorn contains lead, but is this content safe?

According to China's national food hygiene standards, the lead content of puffed food should not exceed 0.5 mg per kilogram. Judging from the above test results, the lead content of four lead-containing popcorn did not exceed the standard. According to the processing technology, the new popcorn should contain no lead, so where does the lead in popcorn come from? Although the lead content does not exceed the standard, will it cause harm to human body?

Experts say that the lead in these popcorn may be produced during transportation and drying. As long as it doesn't exceed the standard, the problem of eating is not big. Although popcorn in supermarkets and cinemas is safe, experts also remind everyone that if you eat too much popcorn, it will get angry and have adverse effects on your health. You should eat popcorn in moderation.
