Abstract

In the present study, 328 carcasses from wild red deer, roe deer, and chamois hunted in fall 2011 were examined for total viable counts (TVC) and Enterobacteriaceae (as indicators of fecal contamination). For this purpose, surfaces of skinned carcasses originating from six small-scale abattoirs were sampled by swabbing. For the examined animal species, TVC mean values ranged from 4.0 to 4.2 log CFU cm-2. The proportion of Enterobacteriaceae positive carcasses was 87.5%, 89.3%, and 90.0% for hunted red deer, roe deer, and chamois, respectively. Enterobacteriaceae mean values accounted for 2.3 (red deer) and 2.6 (roe deer, chamois) log10 CFU cm-2. On the other hand, TVC and Enterobacteriaceae results of carcasses from various abattoirs differed by several orders of magnitude. The low values obtained in certain abattoirs show that carcasses from hunted wild ruminants can be of good hygienic status. To avoid contaminations and to prevent foodborne pathogens from entering the food chain, strict compliance with good hunting and hygiene practices during any step from shooting, through evisceration on
the field, to dehiding, and processing is therefore of central importance.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
