To detect quality safety status of celery, the samples of celery were collected in wholesale vegetable market, farmers market and supermarket. 50 kinds of pesticides including methamidophos and omethoate were investigated, 213 samples were measured and analyzed according to GB 2763—2012 Maximum Pesticide Residue Limits in Foods.
