Excuse me, do you want to ask the reason why Luoding RT Mart was blocked? The reason why Luoding RT Mart was blocked was that enrofloxacin (the sum of enrofloxacin and ciprofloxacin) was detected in the sold bream, which did not meet the national food safety standard 100μg/kg. It is reported that enrofloxacin belongs to fluoroquinolones and is a synthetic broad-spectrum antibacterial drug, which is used to treat skin infections and respiratory infections in animals and is a special drug for animals.
