Recently, the Ningbo Market Supervision Administration released the results of its 22nd food safety inspection for 2025, revealing six batches of substandard samples. Among them, freshwater shrimp sold at the canteen of Bank of Hangzhou's Ningbo Branch was found to contain excessive levels of enrofloxacin residue.
According to China's National Food Safety Standard for Maximum Residue Limits of Veterinary Drugs in Food (GB 31650-2019), the maximum allowable limit for enrofloxacin in poultry and other animal muscles is 100μg/kg. However, tests showed that the enrofloxacin content in this batch of freshwater shrimp reached 1,160μg/kg—11 times above the standard.
Enrofloxacin, a synthetic broad-spectrum antibiotic belonging to the fluoroquinolone class, is exclusively used in animals to treat skin and respiratory infections. Excessive residues in aquatic products may result from improper farming practices, such as overdosing to control diseases or failing to observe withdrawal periods before sale.
Public records indicate that in June 2025, Bank of Hangzhou Ningbo Branch awarded its canteen management contract to New Sun Moon Life Service Group Co., Ltd., with an annual bid of 960,800 yuan. The same company also secured the branch's 2025-2027 cleaning services contract at approximately 323,000 yuan per year.
The Ningbo Market Supervision Administration has ordered local authorities to investigate and penalize the responsible parties in accordance with the law, with details to be disclosed as per regulatory procedures. The findings will also be recorded in the food safety credit archives of the involved producers and operators.
Established in September 1996 and headquartered in Hangzhou, Bank of Hangzhou operates nearly 300 branches across key economic regions, including the Yangtze River Delta, Pearl River Delta, and Bohai Rim. The bank launched its A-share IPO on the Shanghai Stock Exchange on October 27, 2016, and has since established subsidiaries such as Hangyin Wealth Management and Hangyin Consumer Finance.
