Mercury is a metal known for its toxic effects on environmental, animal and human health. The presence of Hg in poultry and its potential impact on food safety still need to be explored, especially considering that poultry is the most consumed source of protein in the global population. This study aimed to systematically review mercury and methylmercury levels in poultry meat and eggs worldwide. The searches were conducted in the Web of Science, PubMed, and Scopus databases, resulting in 123 studies, of which only 30 were deemed suitable. Studies were found across sixteen countries: India, Thailand, Malaysia, China, Poland, Egypt, Ghana, Nigeria, Bangladesh, Iran, USA, Italy, Colombia, Romania, Tanzania, Algeria, and Saudi Arabia. Five poultry species were reported, with chicken being the most recorded species in 16 countries. Among biological samples, eggs and liver were the most used for measuring mercury and methylmercury levels. Levels above those permitted by regulatory organizations such as the United States Department of Agriculture (USDA), China's National Health Commission (NHC), and Thailand's Ministry of Public Health - set at 0.05, 0.05, and 0.02 mg.kg respectively - were observed in 12 of the 17 countries, with the highest concentrations detected in chicken eggs from Colombia. Therefore, poultry production is not Hg-free and contamination by this metal must be monitored.
汞是一种金属，因其对环境、动物和人类健康具有毒性作用而闻名。家禽体内汞的存在及其对食品安全的潜在影响仍有待探索，尤其是考虑到家禽是全球人口消费最多的蛋白质来源。本研究旨在系统综述全球范围内禽肉和禽蛋中的汞及甲基汞含量。检索在科学网、PubMed和Scopus数据库中进行，共检索到123项研究，其中仅有30项被认为合适。研究涉及16个国家：印度、泰国、马来西亚、中国、波兰、埃及、加纳、尼日利亚、孟加拉国、伊朗、美国、意大利、哥伦比亚、罗马尼亚、坦桑尼亚、阿尔及利亚和沙特阿拉伯。报告了5种家禽，其中鸡是16个国家中记录最多的家禽品种。在生物样本中，鸡蛋和肝脏是最常用于测量汞和甲基汞含量的样本。在17个国家中的12个国家观察到了高于美国农业部（USDA）、中国国家卫生健康委员会（NHC）和泰国公共卫生部规定水平（分别设定为0.05、0.05和0.02毫克/千克）的含量，哥伦比亚的鸡蛋中检测到的浓度最高。因此，家禽生产并非无汞，必须监测这种金属的污染情况。
