title: [Analysis on Clenbuterol pollution in swine products in Beijing, 2002].
abstract: OBJECTIVE
  To explore the status of clenbuterol pollution in swine products in Beijing city in 2002.
  
  
  METHODS
  European Union method (EUR 15127-EN Cy2.3) was adopted to examine the samples. Samples were screened by enzyme-linked immunosorbent assay (ELISA) and confirmed by GC-MS. Detected limit of the method was 0.5 micro g/kg. Samples, including lung, liver, pork, kidney and urine of swine, were collected from slaughterhouses, refrigeratories and markets in 11 districts of Beijing.
  
  
  RESULTS
  The results indicated that 185 out of 1 379 samples were positive with an annual positive rate of 13.4%. The highest was 15.7% in lung of swine, followed by urine 15.2% and pork liver 14.0%.
  
  
  CONCLUSIONS
  Rates of detection had decreased from 30.0% to 2.7% during 2002.
