Recently, the employees of Guangxi Entry-Exit Inspection and Quarantine Bureau Aidian Office discovered that three batches of Vietnamese imported peanuts from different owners are moldy and degenerative in different degrees when carrying out site inspection and quarantine. Through laboratory detection of samples, AFB1 of the three batches of goods is far higher than the limit of national standard GB/T5009.22-2003. Meanwhile, the acid value and peroxide index are also out of limits. Finally, those three batches of peanuts are judged as nonconforming, and returned back to the exporting country.
