了解广州市部分食品甲醛残留情况,为食品安全风险评估及政府监管提供参考依据。方法 在全市12个区的餐饮企业、农贸市场、超级市场、批发点4类采样场所,于不同时间采集1 416份样品进行甲醛项目检测。结果 1 416份样品甲醛检测值范围为2.0～4 500.0 mg/kg,甲醛含量大于100 mg/kg占总样品数的13.21%(187/1 416),其中禽类副产品甲醛含量大于100 mg/kg比例为32.63%(31/95)、畜类副产品甲醛含量大于100 mg/kg比例为31.54%(94/298)、鱼类产品(银鱼、九肚鱼、鱼皮)甲醛含量大于100 mg/kg比例为30.85%(29/94)、甲壳类产品(虾仁)甲醛含量大于100 mg/kg比例为19.35%(24/124)；农贸市场与批发点来源样品甲醛含量大于100 mg/kg比例高于超市与餐饮环节；9～11月采集的样品甲醛含量大于100 mg/kg比例高于其他月份,2012—2013年采集的样品甲醛含量大于100 mg/kg比例高于其他年份。结论 广州市甲醛残留量较高的食品主要为畜类副产品的牛百叶、牛心顶,禽类副产品的鹅肠、鸭肠,甲壳类产品的虾仁,鱼类产品的银鱼、九肚鱼、鱼皮等,甲醛残留情况较严重的月份为每年的9～11月,相关部门应加强监管,防范食源性疾病的发生。

Analysis on content of formaldehyde in some foods in Guangzhou in 2006-2015

To understand the situation of formaldehyde residues in some foods from Guangzhou City, and provide reference basis for risk assessment and government supervise.Methods Food sanitation section had collected 1 416 samples for formaldehyde testing at different times in catering industries, meat markets, supermarkets and wholesale markets. Results The range of content was 2.0-4 500.0mg/kg, 13.21% (187/1 416) of the samples were above 100 mg/kg, and the proportion for poultry by-products was 32.63% (31/95), the proportion for animal by-products was 31.54% (94/298), the proportion for fish (whitebait, harpadon nehereus, fishskin) was 30.85% (29/94), and the proportion for crustaceans (shrimp meat) was 19.35% (24/124). The samples from meat markets and wholesale markets had more formaldehyde than the samples from catering industries and supermarkets. The samples collected from September to November had more formaldehyde than the other months. The samples from 2012-2013 had more formaldehyde than the other years. There was significant difference between different species, different sampling sites, different months and different years.Conclusion Some foods had a high level of formaldehyde contamination, such as animal by-products (omasum, beef heart), poultry by-products (goose intestine, duck intestine), crustaceans (shrimp meat) and fish (whitebait, harpadon nehereus, fishskin). It''s relatively more serious from September to November, and the government should strengthen the supervision and prevent foodborne disease.
