text: "The introduction of error feedback systems can lead to a reduction in the
occurrence of errors. Therefore, it was investigated whether the proportion of
contaminated carcasses can be reduced by installing a feedback system (preInspector)
indicating an accumulation of contamination on a pig slaughter line. The technical
equipment for the workplace of a „preInspector“ was installed on the slaughter
line between the evisceration and official meat inspection. The person working
there operated various hand buttons („buzzers“) depending on the type of carcass
defects that occurred. In this case, contamination with tubular rail fat and faecal
contamination, on the belly and/or on the back, were registered. Other defects
were related to the plucks (tongue, trachea, oesophagus, lungs, heart, diaphragm,
liver), intestinal package, hair and claw removal. After inspecting the carcass
halves and activating the buzzer, the signals were collected. The detection was
automatically assigned to the corresponding pig.\r\nThe average slaughter rate
was 1200 pigs per hour. As soon as the number of contaminations rose above a threshold
of 50 contaminations per 60-minute time interval, a light signal was triggered
at the corresponding workstations on the slaughter line. On average, 981 positive
buzzer activities related to contaminations per day were detected, with large
fluctuations of the frequency between 323 and 1,752. An influence on the frequency
of contamination occurrence through the feedback to the corresponding workstations
was not observed."
