SUMMARYIn a field trial on Integrated Quality Control offinishing pigs we evaluated information written on Quality Information Cards (QUIC) for meat inspection purposes. These cards were sent with 3747 shipments of pigs going from the finishing herd to the slaughterhouse. Pig suppliers answered five questions dealing with health problems and the use of drugs during the finishing period By comparing QUIC answers to recorded post-mortem abnormalities, we found that the information on the QUIC had some, albeit low, predictive value with respect to the abnormalities 'arthritis', 'condemned liver' and lung lesions. Shipments without a QUIC or with a faulty QUIC were considered 'suspect' because higher levels of abnormalities were found in these shipments. These results indicate the potential use of a QUIC.

“…a history of above average condemnation rate. Harbers et al (1991) concluded that previous post-mortem meat inspection findings cannot be used as predictor, partly because of great variation between individual shipments, but it could play a role signaling farms that are likely to deliver pigs with higher level of abnormalities. In this study, we explored the possibility to overcome the problem of unexpected variation between individual shipments with reliable FCI and prior historical data, and created a simple scoring system of slaughter batches to facilitate the current visual meat inspection system.…”

Meat inspection now incorporates a more risk-based approach for protecting human health against meat-borne biological hazards. Official post-mortem meat inspection of pigs has shifted to visual meat inspection. The official veterinarian decides on additional post-mortem inspection procedures, such as incisions and palpations. The decision is based on declarations in the food chain information (FCI), ante-mortem inspection and post-mortem inspection. However, a smooth slaughter and inspection process is essential. Therefore, one should be able to assess prior to slaughter which pigs are suitable for visual meat inspection only, and which need more profound inspection procedures. This study evaluates the usability of the FCI provided by pig producers and considered the possibility for risk ranking of incoming slaughter batches according to the previous meat inspection data and the current FCI. Eighty-five slaughter batches comprising 8954 fattening pigs were randomly selected at a slaughterhouse that receives animals from across Finland. The mortality rate, the FCI and the meat inspection results for each batch were obtained. The current FCI alone provided insufficient and inaccurate information for risk ranking purposes for meat inspection. The partial condemnation rate for a batch was best predicted by the partial condemnation rate calculated for all the pigs sent for slaughter from the same holding in the previous year (p<0.001) and by prior information on cough declared in the current FCI (p=0.02) statement. Training and information to producers are needed to make the FCI reporting procedures more accurate. Historical meat inspection data on pigs slaughtered from the same holdings and well-chosen symptoms/signs for reporting, should be included in the FCI to facilitate the allocation of pigs for visual inspection. The introduced simple scoring system can be easily used for additional information for directing batches to appropriate meat inspection procedures. To control the main biological public health hazards related to pork, serological surveillance should be done and the information obtained from analyses should be used as part of the FCI.

“…the pig supplier should be convinced of the necessity of guaranteeing the quality of preselection; clear definitions of relevant symptoms/findings are available; the pig supplier has to be financially rewarded for correctly carrying out a preselection (17); information from the meat inspection should be fed back to the pig supplier (6,9) to give him information on his preselection and to improve herd manangement and productivity.…”

SUMMARYThe ability of pig suppliers to separate pigs with abnormalities from pigs without abnormalities at the end of the finishing period was investigated Nineteen hundred and seventy-eight pigs, delivered by 22 pig suppliers, were involved in the experiment The pigs were inspected on the farm by the pig supplier and separately, by a veterinary expert The animals were sent in 22 deliveries to one slaughterhouse. A veterinary meat inspector carried out the ante-and post-mortem inspections. The results of the inspections were compared The measure of agreement,
