Antibacterial activity of decontamination treatments for pig carcasses


Loretz, M; Stephan, R; Zweifel, C (2011). Antibacterial activity of decontamination treatments for pig carcasses. Food Control, 22(8):1121-1125.

Abstract

Prevention or reduction of carcass contamination with food-borne pathogens during slaughter is of particular importance. Antimicrobial intervention technologies are therefore gaining increasing interest in the slaughter process. In this review, we screened the available recent literature on the decontamination of pigcarcasses and appraised the antibacterialactivity of treatments. Compared to poultry and beef carcasses, data on decontaminationtreatments for pigcarcasses are so far limited and mainly physical and chemical interventions were investigated. Physical treatments were on the one hand part of the normal pig slaughter process. Dependent on time and temperature conditions, the bactericidal effect of scalding was shown in several studies, whereas the effect of singeing or chilling differed widely. On the other hand, interventions as hot water spraying, steam treatment or ultraviolet light were additionally applied with the specific objective of carcassdecontamination. Hot water spraying and steam treatment thereby yielded bacterial reductions ranging from 1.0 to 2.1 orders of magnitude. Chemical interventions primary included lactic and acetic acid. Under commercial conditions, lactic acid treatment yielded bacterial reductions ranging from 0.2 to 1.0 orders of magnitude.

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.
