The Government yesterday (August 19) announced the investigation results regarding an incident of urine samples from pigs imported from the Mainland detected with prohibited veterinary drug in early August. Owing to the failure on the part of their staff at Sheung Shui Slaughterhouse in strictly observing the established procedures and guidelines on that day and inadequate communication between staff, the Food and Environmental Hygiene Department (FEHD) could not prevent some of the pigs in question from being slaughtered and discharged to the market. In addition, the incomplete transaction records of live pigs at the wholesale and retail levels have led to the release of an inaccurate retailer list.

The Secretary for Food and Health, Dr Ko Wing-man, said, "The responsibility of the incident rests with the Government. I apologise again to members of the public and the relevant stakeholders. The FEHD has issued a letter of apology to the 27 retailers affected in the incident. To offset their loss, the retailers will be granted a one-off ex-gratia payment for the pork and pig offal disposed of. The amount of ex-gratia payment will be calculated according to the market price of pork announced by the Census and Statistics Department and the disposed amount. We thank the trade for their cooperation with the Government in our investigation and follow-up work."

"In the light of the investigation results, the Government will further enhance the entire work flow of the slaughterhouses, including advancing the time for announcing test results, strictly implementing the code of practice and procedures of the slaughterhouses, stepping up staff training to increase their vigilance, strengthening the monitoring by escalating to the senior management level in case of any unusual test results; improving the live pigs transaction record system and heightening spot checks of the records. These measures are to ensure that the fresh pork supplied to the retail market has passed through stringent surveillance and are safe and fit for human consumption. Under the overarching principle of ensuring food safety, the Government will continue to communicate with the various stakeholders of the supply chain with a view to perfecting the whole supply work flow."

On the investigation result of the incident, the Director of Food and Environmental Hygiene, Miss Vivian Lau, said that according to the established mechanism and departmental guidelines, samples are collected from every batch of food animals admitted to the slaughterhouses in Hong Kong for testing of chemicals and veterinary drug residues. If there are samples found to be unsatisfactory, the affected batch of the animals will be detained and destroyed. The slaughtering of pigs should not be started before negative test results are confirmed. If the pigs concerned are slaughtered, they should not be released and delivered to the market for sale.

Miss Lau said, "We have reviewed the whole testing and slaughtering procedures. The investigation found that after being informed by the Agriculture, Fisheries and Conservation Department (AFCD) on the preliminary test result that some pig urine samples failed to pass the test and that further testing was required, the staff of the Agricultural Chemicals and Veterinary Drugs Unit (ACVD) of the Centre for Food Safety failed to ensure that the importer detained the affected pigs in a timely manner and the Meat Inspection Unit (MIU) of the FEHD in the Sheung Shui Slaughterhouse got all relevant information. Without obtaining information indicating that the samples concerned had passed the tests, the MIU staff did not suspend inspection of the affected pigs nor did they detain the pig carcasses concerned. When the MIU staff later learned about the preliminary test results of the affected batch of pigs from the ACVD and started stopping the delivery of the pigs concerned, some affected pigs had already been transported out of the slaughterhouse."

"This incident showed that there was room for improvement for the staff of the two units in following the established procedures and departmental guidelines. Communication between the parties concerned was also inadequate and crucial messages were not conveyed at the critical moment. In the end, they failed to fully function as the gatekeeper, causing some affected pork entering the market."

"Regarding the tracing of the affected pork, we found that the operator of the slaughterhouse did not maintain entirely accurate information on the retail outlets. In addition, different importers imported pigs from one of the affected farms on August 3 and 4 and some of the pigs from the two batches were slaughtered at Sheung Shui Slaughterhouse together on August 5. Since the computer system of the operator did not keep the records of the importers for distinguishing the two batches of pigs, this made it more difficult for the FEHD to trace the distribution of the affected pork."

"On following up on the list of the retail outlets, the retail outlets and the buyers concerned provided their transaction records to us upon our requests earlier. During verification, we found that some of the transaction records were incomplete. Further investigation revealed that all of the 27 affected retail outlets announced on August 5 had been supplied with pigs imported from the affected farms and slaughtered at Sheung Shui Slaughterhouse on that day. Among them, 11 outlets were supplied with the affected pigs imported on August 4. The remaining 16 outlets were supplied with pigs imported on August 3 which had passed the urine test. We have issued a letter of apology to them."

In view of the investigation result, the FEHD has taken and will take the following measures:

The FEHD and the AFCD agreed to expedite the notification of urine test results of pigs. The AFCD will notify the ACVD of the FEHD the results of the last round of urine test on or before 9.30pm every night. The ACVD will then inform the staff of the MIU, the slaughterhouse operator and the importer about the test results. Before a test result confirming that the pigs are 100 per cent safe is available, the slaughterhouse operator will not commence slaughtering the pigs. If any problem is found ( i.e. the pigs fail the test and further testing is needed or the test results are not available yet), the staff will immediately notify the importers, slaughterhouse operator, agents and buyers to work together to detain the affected pigs.
The FEHD has strengthened the monitoring measures. At 9.30pm every night, the ACVD's staff will notify the management of the test results of the samples known at that time. Should any unusual circumstances come to light during the testing, slaughtering or operation, the ACVD and the MIU staff will immediately report to the management for appropriate follow-up. The department has also reminded all staff concerned and the slaughterhouse operator to act strictly according to the established procedures and departmental guidelines.
The FEHD has reviewed the mode of communication between staff of the two units. It will also enhance training and conduct drills for the staff concerned to enhance future communications and ensure timely contingency response.
To improve the tracing mechanism, the FEHD will form a working group with relevant stakeholders, including importers, slaughterhouse operator, buyers and retailers, to discuss the establishment of a reliable record keeping system to ensure information of the distributors and retail outlets involved in the transaction is correct in order to facilitate the tracing of distribution when need arises.


"We believe the above measures can help strengthen monitoring of the slaughterhouse's operation. We will also exercise stringent control by strictly following the established procedures and departmental guidelines to ensure that the pork for sale in the market has passed relevant tests so as to prevent recurrence of similar incidents and to safeguard food safety and public health," Miss Lau said.

"I hope members of the public understand that the FEHD staff who work in the slaughterhouse have all along been performing their duties diligently. The department will seriously follow up on the problems reflected in the incident including inadequate internal communication and delays. If any members of staff are found to have violated rules and regulations, the department will handle the matter as soon as possible in accordance with the guidelines and procedures stipulated by the Civil Service Bureau and conduct the investigation in a fair and impartial manner," she said.

As regards the source of veterinary drug, it was found that the concentration level of veterinary drug in relevant urine samples was abnormal. According to past experience, pig farmers attempting to use veterinary drugs to promote the growth of lean meat would stop the medication somewhat before discharging the pigs for slaughtering in order to reduce the chance of detection. As such, the possibility of the farms being the source of veterinary drugs should be ruled out. The Government will continue to follow up and work on the incident in order to find out the cause of the abnormal situation.
