  text: In this study, we examined the possibility of detecting different types of
    materials that contaminate carcasses during industrial pig slaughter using video
    image analysis and artificial intelligence (AI). A camera system was installed
    between evisceration and postmortem meat inspection on an industrial pig slaughter
    line with a capacity of 12,000 pigs per day. The pigs were photographed using
    five 2D cameras, and the images were analysed for contamination using an AI-based
    algorithm. The setup, which was developed and installed by CLK GmbH, performed
    under industrial conditions. In order to train the system, specifications were
    created for the most frequently occurring types of contamination, namely, intestinal
    contents, bile, stomach contents, and tubular rail fat. Afterward, the system
    was trained using annotated images. In principle, the system was able to recognize
    all types of contamination on the camera images; even pinhead-sized contaminations
    were visible. The agreement between the algorithm and the results of an expert
    assessor who assessed the images online agreed in 60% of the judgements. The agreement
    between experts using onsite assessment and those using online assessment by images
    was 73%. Thus, the kappa measure of agreement was κ = 0.1215 (p = 0.0199). Significantly
    higher recognition rates appear to be possible by adjusting the algorithm and
    increasing the number of training images. Thus, the system is a useful tool to
    preselect contaminated carcasses and to support postmortem inspection.

  text: 'The aim of this study was to investigate if vibroacoustic methods may be
    used for the non-destructive determination of beef during its aging process. The
    vibroacoustic method was based on the observation of mechanical changes in the
    meat during the aging process and was compared with reference data obtained by
    Warner-Bratzler shear force measurement as well as sensory testing of the tenderness
    using a ten-part scale. To evaluate the mechanical properties, transfer functions
    were used representing the time dependency of the signal and thus the viscoelastic
    behaviour. In this study, a total of 31 roastbeef samples from 16 different young
    bulls and two older cows were examined from day of slaughter to day 21 of cold
    storage with regard to their tenderness. For this purpose, vibroacoustic measurements
    were carried out on the unprocessed/raw meat at intervals of 1–3 days. The reference
    measurements using sensor technology and Warner-Bratzler shear force measurement
    were carried out on the first (day of slaughter) and last (21st day) day on slices
    of roast beef cooked with saturated steam. In the results of all three methods,
    the shear force measurement, the sensory test and the vibroacoustic method, showed
    that roastbeef from the same animal but different halves produced different results.
    Basically, it is possible to predict the tenderness of roastbeef by taking measurements
    at the beginning of the maturing process for the end of the maturing period using
    vibroacoustic methods: Data analysis led to a trend function that roughly reflects
    the actual tenderness, which is generally higher than the real tenderness represented
    by the shear-force measurement. In order to obtain a better resolution for recording
    the mechanical changes during the aging process, the measurements should be carried
    out at shorter intervals.'

  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."

  text: 'During pig slaughter, contaminants such as intestinal and stomach contents,
    bile, tubular rail fat, and reddish foam from the respiratory tract frequently
    appear on carcasses, potentially compromising meat safety. This study examined
    the impact of these contaminants on the bacterial loads of pig carcasses, using
    total bacterial counts and Enterobacteriaceae counts as hygiene indicators. Examination
    of the substances as such showed that intestinal and stomach contents were particularly
    conspicuous to undermine the carcase hygiene due to total bacterial counts of
    similar to 6.0 log10 CFU g-1 (intestinal content) and 5.5 log10 CFU g-1 (stomach
    content). Tubular rail fat showed varying contamination levels, from low (3.1
    log10 CFU g-1) to high (6.4 log10 CFU g-1). The reddish foam had moderate contamination
    (4.3 log10 CFU g-1). Enterobacteriaceae levels mirrored these results at a lower
    level. Subsequently, a comparative study analysing bacterial levels in contaminated
    and in noncontaminated pork rind regions was performed. Even small amounts of
    intestinal and stomach contents led to significant increases in total bacterial
    counts of up to 3 log10 CFU cm-(2) and in Enterobacteriaceae counts (up to 5 log10
    CFU cm-(2)). Other contaminants did not significantly raise bacterial levels:
    their total viable counts around 3.5 log10 CFU cm-(2) were similar to those of
    uncontaminated carcass areas. Nevertheless, they should be removed before further
    processing.'

- lang: eng
  text: The aim of the study is to provide an up-to date overall evaluation of visual
    contamination occurring on the slaughter line in order to provide a basis for
    implementing contamination control measures and to the hygienic quality of the
    processes. For this purpose, 627 contaminated pig carcasses in an industrial slaughterhouse
    in north western Germany were examined in 2021 for its distribution of type, areal
    extent and localization of slaughter contamination. Prior to official meat inspection,
    two persons visually scanned dorsal and ventral surfaces of the eviscerated but
    not yet split pig carcasses from cranial to caudal and recorded types, areal extent
    and localization of the contamination. The main contamination type were intestinal
    contents, bile, stomach contents, tubular rail fat and “others”, which mostly
    consisted of a reddish foam from the respiratory tract. 103 out of 627 contaminated
    animals showed more than one contamination, which leads to a total number of 754
    contaminations detected. Intestinal contents accounted for almost half of all
    contaminations and “others” for 30%. Forelimb, back and ham together counted for
    70% of the contaminated regions. The affected area was smaller than that of a
    one euro coin (diameter about 23 mm) in 86% of the cases.
