Food Partner Network News On October 25, the Shandong Provincial Market Supervision and Administration Bureau announced the 52nd phase of food sampling information, 27 batches of samples on the unqualified list, detected agricultural and veterinary drug residues exceeded the standard, food additives exceeded the scope of use, quality indicators did not meet the standard, microbial pollution, heavy metal pollution, other pollutants exceeded the standard, organic matter pollution problems, food additives and label values did not match the label and other issues.
Seven batches of samples detected excessive residues of agricultural and veterinary drugs
Among the unqualified samples, 7 batches of samples were detected to have excessive residues of agricultural and veterinary drugs. Among them, 4 batches of samples were detected to have pesticide residues exceeding the standard, namely: triazole phosphorus detected that the orange sold by Taian Lingyun Trading Group Co., Ltd. did not meet the national standards for food safety; ordinary cabbage (small rapeseed) sold by the Lilan new vegetable business department in Liangshan County was found to be ineligma that did not meet the national standards for food safety; and the rapeseed (ordinary cabbage) sold by the garden vegetable fresh supermarket in Changqing District was found to be metaminoavermectin benzoate that did not meet the national standards for food safety Cowpea sold by Jinge Vegetable Trading House on the outskirts of Tengzhou City was found to be infestamine and did not meet the national standards for food safety.
According to the National Standard for Food Safety The maximum residue limit of pesticides in food (GB 2763-2021), the maximum residue limit of triazolium in citrus is 0.2mg/kg; the maximum residue limit of acetamidine in ordinary cabbage is 1mg/kg; the maximum residue limit of methylaminoavermectin benzoate in ordinary cabbage is 0.1mg/kg; and the maximum residue limit value of spiromide in cowpea is 0.5mg/kg.
In addition, 3 batches of samples detected veterinary drug residues exceeding the standard, namely: the carp detected by Jining Ruihe Trading Co., Ltd. did not meet the national standards for food safety; the pig liver sold by Yantai Jiajiayue Supermarket Co., Ltd. Guanli Store detected enrofloxacin and sulfonamides (total) did not meet the national standards for food safety; the crucian carp sold by Laozhang Fish Shop in Shanting District was detected that Enrofloxacin (the sum of Enrofloxacin and ciprofloxacin) did not meet the national food safety standards.
Enrofloxacin is a third-generation quinolone, which is a class of synthetic broad-spectrum antibacterial drugs used to treat skin infections and respiratory infections in animals, and is exclusive to animals. The National Standard for Food Safety The maximum residue limit of veterinary drugs in food (GB 31650-2019) stipulates that the maximum residue limit of enrofloxacin in the liver of pigs is 200 μg/kg, and the maximum residue limit value in the skin and meat of fish is 100 μg/kg.
Sulfonamides (total) are synthetic broad-spectrum bacteriostatics that are effective against most Gram-positive and Gram-negative bacteria. It is more effective in the treatment of avian coccidiosis and chicken leukocytosis. Long-term consumption of foods with excessive residues of sulfonamides may accumulate in the human body, which will cause harm to human body functions, and may also cause allergic reactions and the emergence of drug-resistant strains. The National Standard for Food Safety The maximum residue limit of veterinary drugs in food (GB 31650-2019) stipulates that the maximum residue limit of sulfonamides in the muscles and livers of all food animals is 100 μg/kg.
Diazepam is a benzodiazepine sedative hypnotic drug, clinically used for anti-anxiety, sedative hypnosis, anticonvulsant, anti-epileptic and central muscle relaxation effects. The National Standard for Food Safety The maximum residue limit of veterinary drugs in food (GB 31650-2019) stipulates that diazepam is a veterinary drug that is allowed for therapeutic use, but shall not be detected in animal food. The reason for the detection of diazepam in freshwater fish may be to reduce the perception of the outside world by fresh live fish and ensure that it is still alive after transportation and is used illegally.
4 batches of samples detected food additive use problems
Among the unqualified samples, 4 batches of samples were detected to have problems with the use of food additives. Among them, 3 batches of aluminum residues (dry samples, measured in Al) did not meet the requirements of national food safety standards, namely: fried fritters processed by Dongming County Tang Congee Yupin Fast Food Restaurant, fritters processed by Nanguan Maido Fast Food Restaurant in Weicheng District, and bean buckles sold by Netcom store of Zibo Nova Supermarket Chain Co., Ltd.
Aluminum-containing food additives, such as potassium aluminum sulfate (also known as potassium alum), ammonium aluminum sulfate (also known as ammonium alum), etc., are used as leavening agents and stabilizers in food, and aluminum residues will be generated after use. Aluminum-containing food additives will not cause harm to health when used according to standards, but long-term consumption of foods with aluminum exceeding standards will lead to a decline in exercise and learning and memory, affecting children's intellectual development. The National Standard for Food Safety The Standard for the Use of Food Additives (GB 2760-2014) stipulates that the maximum residue limit value of aluminum in fried noodle products and legume products (dry samples, measured in Al) is 100mg/kg. The reason why the residual amount of aluminum (dry samples, in terms of Al) in fried noodle products and bean products exceeds the standard may be that individual merchants use aluminum-containing food additives in excess of the limit in the production and processing process in order to increase the taste of the product, or the aluminum content in the compound additives used is too high.
In addition, the tofu sold by Li Yugang Delicatessen in Juxian County was found to be benzoic acid and its sodium salt (in terms of benzoic acid) that did not meet the national standards for food safety.
Microbial contamination problems were detected in 5 batches of samples
Among the unqualified samples, 5 batches of samples were detected with microbial contamination problems. Among them, the total number of bacteria detected in 3 batches of samples did not meet the requirements of the national food safety standards, namely: the sausages sold by The Xingqin Food Store in Juxian County, which were nominally produced by Shengxiangzhai Meat Products Factory in Laiwu District, Jinan City; the purple rice bread produced by Shandong Fuji Food Co., Ltd., which was sold at Sanze Jiahong Shopping Plaza in Xincheng, Yangxin County; and the red sausages produced by Liaoning Zhisheng Food Co., Ltd. sold by Jia Chao Vegetable and Fruit Supermarket on Kangning Road in Taierzhuang District.
The total number of colonies is an indicative microbial indicator, not a pathogenic indicator, reflecting the hygienic status of the food in the production process. If the total number of colonies in food is seriously exceeded, it will destroy the nutritional composition of food and make the food lose its edible value; it will also accelerate food spoilage, which may endanger human health. The National Standard for Food Safety Cooked Meat Products (GB 2726-2016) stipulates that the total number of colonies of cooked meat products (except fermented meat products) for the same batch of products shall not exceed 105 CFU/g, and the test results of up to 2 samples shall exceed 104 CFU/g. The National Standard for Food Safety In Pastries and Bread (GB 7099-2015) stipulates that the total number of colonies tested for the same batch of pastry products in 5 samples shall not exceed 105 CFU/g, and the test results of up to 2 samples shall exceed 104 CFU/g. The reason why the total number of colonies in smoked sausage ham products and pastries exceeds the standard may be that the enterprise has not strictly controlled the sanitary conditions of the production and processing process according to the requirements, and may also be related to the improper sealing of the product packaging or improper storage and transportation conditions.
There are also 2 batches of unqualified samples: Jinxiang County Jinxing Commercial and Trade City Jiaze Bottled Water Business Department sold packaged drinking water (other drinking water) produced by Jinxiang County Yuanguanquan Drinking Water Factory found to be pseudomonas aeruginosa does not meet the national standards for food safety; self-disinfecting tableware (bowls) used in Xujia Noodle House in Xinghua Village, Tengzhou City, detected coliform bacteria that do not meet the national standards for food safety.
1 batch of samples was detected to exceed the lead standard
Among the unqualified samples, 1 batch of samples was found to be lead (in terms of Pb) that did not meet the provisions of the national food safety standards, which were: The label sold by Cao Chunkun Food Additives Trading House in Linyi Mall is called the compound enzyme preparation antioxidant produced by Shandong Wufeng Biotechnology Co., Ltd.
Lead is a common pollutant of heavy metals that can seriously endanger human health. Long-term consumption of food with excessive lead may cause damage to the human blood system and nervous system, especially on children's growth and intellectual development. The reason why the detection value of lead (Pb) in compound food additives exceeds the standard may be that the lead content in the raw materials used by the production enterprise exceeds the standard, or it may be the lead migration in the production equipment or packaging materials.
3 batches of samples detected other contaminants exceeding the standard
Among the unqualified samples, 3 batches of samples were detected to have other pollutants exceeding the standard. Among them, 2 batches of nitrite (in terms of NO2-) detected did not meet the requirements of the national food safety standards, namely: packaged drinking water sold by Liqun Group Zibo Shopping Plaza Co., Ltd., which is nominally produced by Qingdao Baifuyuan Drinking Water Co., Ltd.; and Jingdo packaged drinking water produced by Taian Bainian Health Technology Co., Ltd.
Nitrite can reflect the contamination of water to a certain extent, and drinking water with serious excess of nitrite may cause poisoning. The National Standard for Food Safety (GB 2762-2017) stipulates that the maximum limit value of nitrite (in terms of NO2-) in packaged drinking water (except mineral water) is 0.005mg/L. Nitrite in the water can be converted from nitrate, nitrate has natural and human sources, after the water is contaminated by bacteria, bacteria will release nitrate reductase at a certain temperature, reducing the nitrate in the water to nitrite, and if the disinfection control is improper, it will also lead to an increase in the concentration of nitrite in the water transmission system.
In addition, the self-disinfecting tableware (dinner plate) used in the Fat Ni Split Wood Chicken Yard in Juye County was found to be anionic synthetic detergent (based on sodium dodecylbenzenesulfonate) that did not meet the national standards for food safety.
Anionic synthetic detergent, that is, the main components of detergents such as detergents often used in our daily lives, its main component sodium lauryl sulfonate, is a low-toxic substance, because of its convenient use, easy to dissolve, good stability, low cost and other advantages, widely used in disinfection enterprises, but if the meal (drink) cleaning and disinfection process is improperly controlled, it will cause detergent residues on meal (drink) utensils, adverse effects on human health. The National Standard for Food Safety Disinfection Meal (Drink) Appliance (GB 14934-2016) stipulates that the anionic synthetic detergent of meal (beverage) utensils using chemical disinfection method shall not be detected. The reason for the detection of anionic synthetic detergent in the meal (drink) utensils may be that the detergent used by some units is unqualified or the amount of detergent used is too large, and the washing water in the tableware rinse pool is not rinsed with enough water or the tableware rinse pool is reused or the number of tableware is large, resulting in cross-contamination, and then residual in the meal (drink) utensils.
A batch of samples detected organic contamination problems
Among the unqualified samples, 1 batch of samples detected organic matter contamination problems, namely: the small ground sesame oil produced by Shan County Huahui Sesame Oil Co., Ltd. was found to be benzo[a]pyrene that did not meet the national standards for food safety.
Benzo[a]pyrene is a polycyclic aromatic hydrocarbon compound of the persistent organic pollutant, which is chemically stable and has teratogenic, carcinogenic and reproductive toxicity. The National Standard for Food Safety (GB 2762-2017) stipulates that the maximum limit value of benzo[a]pyrene in oils and fats and their products is 10 μg/kg. The reason for the excessive benzo[a] pyrene in edible vegetable oil may be that the high temperature causes the benzo[a] pyrene content to rise when the raw materials are repeatedly baked, roasted or fried during the production process; it may also be contaminated by contact with lubricating oil during processing and the use of extraction solvents that do not meet the requirements; it may also be that oil crops absorb benzo[a] pyrene in the soil, water and atmosphere during the planting process, or are contaminated in the process of storage, drying and so on.
In addition, there are 5 batches of samples detected that the quality indicators do not meet the standards, and 1 batch of samples detected that the food additives do not match the labeled values, namely: the high-quality cotton white sugar sold by Jia Tesco Supermarket in Pingyi County, which is called Tengzhou Aohua Food Factory, detects that the total sugar content and reduced sugar are not in line with the national standards for food safety; the reduced sugar produced by Feicheng Zhengyan Food Co., Ltd. sold by the Sun Xiuhua Store Department of Feicheng City does not meet the national standards for food safety; The conductivity of Taishan Yaochi drinking water sold by The porridge shop in Daiyue District, Tai'an City, which is called Tai'an Linyue Beverage Co., Ltd., did not meet the national standards for food safety; the acid price (in terms of fat) (KOH) of the bean-fragrant bread sold by the sincere vice-food supermarket sold by the sincere vice-food supermarket in Binzhou High-tech Industrial Development Zone was detected as the acid price (in terms of fat) (KOH) of the bean-fragrant bread produced by Zouping Sanyi Food Co., Ltd The acid price of the small mill sesame sesame oil produced by Heze Peony District Fidelity Sesame Oil King Co., Ltd. sold by Yinmao Shopping Center in Mudan District, Heze City (measured in KOH) did not meet the national standards for food safety; the five-spice sauce beef sold by Weifang Luxian Supermarket, which was labeled as Weifang Kangshi Shengyuan Food Co., Ltd., was found to be dehydroacetic acid and its sodium salt (measured in terms of dehydroacetic acid) and did not meet the requirements of product labeling.
For the unqualified products found in the sampling inspection, the market supervision department where the producer and operator is located has ordered the enterprise to find out the product flow, recall and remove the unqualified products, control the risks, and analyze the reasons for rectification, and the unqualified products involved have been verified and disposed of as required.
