Food as a source of exposure to nickel

Abstract

According to the European Food Safety Authority (EFSA), food is the main source of nickel intake by the general population. Based on the risk assessment, EFSA determined the tolerable daily intake of this element (TDI) from all sources at the level of 2.8 μg/kg body weight, which is for an adult 196 μg, while for a child 56 μg. The Benchmark Dose Lower Confidence Limit (BMDL10) associated with dermatitis at 1.1 μg/kg body weight was also determined as well as the Margin of Exposure (MOE). Nickel intake in the Member States varies and depends on consumption habits. CONTAM Panel of EFSA considered the unlikely possibility of developing cancers related to the intake of nickel with food. According to experts, other harmful effects on the human body are more often identified. An additional aspect requiring further investigations that will allow an actual estimation of exposure associated with intake of this element by various groups of population is the issue of nickel absorption in the human body. The review of the EFSA opinion on the request of the European Commission planned in the near future based on the collected data as part of the action of the Commission Recommendation (EU) 2016/1111 on monitoring the presence of nickel in food will contribute to taking appropriate actions related to consumer protection, including the most vulnerable groups of population.

“…Based on the Nutrition and Health Survey report and vegetable calorie counts, the MIDVC in Taiwan during 2013–2016 was 0.133 kg d −1 [ 43 ]. The TDIs of Cd, Cu, Ni, and Zn set by the European Food Safety Authority (EFSA) [ 52 , 53 ] and the Joint FAO/WHO Expert Committee on Food Additives (JECFA) [ 54 , 55 ] were 0.36, 500, 2.8, and 300 μg kg −1 -BW d −1 , respectively. …”
