In addition to the results of heavy metal indicators, nitrofuran metabolites were also detected. At the same time, some samples also detected residues of prohibited fish drugs such as enrofloxacin, ciprofloxacin, chloramphenicol, malachite green and erythromycin, and some samples exceeded the standard.
If a large number of nitrofurans are ingested for a long time, it may cause cancer. Long-term consumption of animal food containing antibiotic residues will also lead to antibiotic resistance of pathogenic bacteria and affect clinical efficacy.
