Contaminants in food: Health risks of natural origin are frequently underestimated


Just under 60 percent of the German population view undesirable substances in food as a high or very high health risk. The most well-known of these substances, which are scientifically denoted as contaminants, are mercury compounds and dioxins. In contrast, only around 13 percent of respondents have heard of the natural contaminants pyrrolizidine alkaloids (PAs) in honey or tea – and only roughly one in three of those who have heard of PAs believe these substances pose a significant health risk.
