Abstract
Description
La présente invention concerne un procédé de traitement de désinfection d'emballages d'oeufs. The present invention relates to a method of disinfecting treatment of egg packages.
Les neufs qui sont pondus par des volailles en un lieu de ponte sont mis dans des emballages pour être transportés à un centre de conditionnement où ils seront alors conditionnés pour la commercialisation vers les points de vente. Les emballages utilisés entre le lieu de ponte et le centre de conditionnement sont généralement détruits pour éviter la contamination du lieu de ponte, notamment aux bactéries <I>Salmonella</I> enterifdis et Typhimurium. New ones that are laid by poultry at a nesting place are put in packages to be transported to a packing center where they will then be packaged for marketing to the points of sale. Packagings used between the spawning site and the packing center are usually destroyed to prevent contamination of the spawning site, in particular the <I> Salmonella </ I> enterifdis and Typhimurium bacteria.
Un arrêté du 08/12/1998 publié dans le J.O. stipule que "les emballages en carton ne doivent pas être réemployés. Ceux qui sont fabriqués en matériaux permettant le nettoyage et la désinfection peuvent être réutilisés sous réserve d'avoir subi ces opérations". A decree of 08/12/1998 published in the J.O. states that "cardboard packaging must not be reused.Those made of materials allowing cleaning and disinfection can be reused subject to having undergone these operations".
C'est dans ce contexte que l'on a recherché un procédé de traitement de désinfection qui non seulement permette une désinfection totale des emballages, mais qui ne les endommage pas, ce qui les rendrait inutilisables. It is in this context that a disinfection treatment process has been sought which not only allows total disinfection of the packages but does not damage them, rendering them unusable.
A cette fin, un procédé de traitement de désinfection selon la présente invention est caractérisé en ce qu'il consiste à soumettre lesdits emballages à un rayonnement ionisant, par exemple à une dose au moins égale à 2 kGy (ge 20 kilorads). On a pu montrer qu'en tout état de cause, cette dose pouvait être inférieure à 5 kGy. On notera que plus la dose est faible, plus la mise en oeuvre du procédé est économique. For this purpose, a disinfection treatment method according to the present invention is characterized in that it consists in subjecting said packages to ionizing radiation, for example at a dose of at least 2 kGy (ge 20 kilorads). It has been shown that in any case this dose may be less than 5 kGy. Note that the lower the dose, the more the implementation of the process is economical.
Les rayonnements utilisés sont par exemple des rayonnements y. The radiation used is, for example, radiation y.
Pour montrer l'efficacité du procédé de la présente invention, on a pratiqué de la manière suivante. To demonstrate the effectiveness of the process of the present invention, the following procedure was practiced.
On a inoculé chaque alvéole d'un emballage, originairement stérile, par 1 millilitre d'une culture de Salmonella enteritidis ou de<I>Salmonella</I> typhimurium ajustée à 109 bactéries/ml. Puis, dans un environnement stérile, on a laissé le dépôt ainsi réalisé s'absorber dans le carton de l'emballage, ce qui peut demander environ une heure. Each cell of an originally sterile package was inoculated with 1 milliliter of a Salmonella enteritidis or Salmonella typhimurium culture adjusted to 109 bacteria / ml. Then, in a sterile environment, the deposit thus formed was allowed to absorb into the carton of the package, which may take about one hour.
On a ensuite appliqué audit emballage le traitement d'ionisation au rayonnement y selon la présente invention à une dose de 4,5 kGy. The y-radiation ionization treatment according to the present invention was then applied to said package at a dose of 4.5 kGy.
Enfin, on a recherché des traces de la culture de<I>Salmonella</I> enterifdis ou de <I>Salmonella</I> typhimurium par une méthode classique à quatre étapes successives de pré-enrichissement, enrichissement, isolement et identification. Ainsi, on a pu montrer que les alvéoles d'emballage ainsi traitées sont dépourvues de<I>Salmonella</I> enteritidis et Typhimurium, même lorsque celles-ci ont été préalablement audit traitement, ensemencées avec un inoculum composé de<B>109</B> <I>Salmonella</I> enteritidis et 109<I>Salmonella</I> typhimurium. Finally, traces of the culture of Salmonella enterifdis or Salmonella typhimurium were investigated by a conventional method at four successive stages of pre-enrichment, enrichment, isolation and identification. Thus, it has been possible to show that the packaging cells thus treated are devoid of <I> Salmonella </ I> enteritidis and Typhimurium, even when these were previously said treatment, seeded with an inoculum composed of <B> 109 <I> Salmonella </ I> enteritidis and 109 <I> Salmonella </ i> typhimurium.
On a également pu montrer que les alvéoles des emballages peuvent résister à des doses relativement élevées de l'ordre de 100 kGy, ce qui prouve leur bonne tenue à des doses relativement plus faibles. It has also been shown that the cells of the packages can withstand relatively high doses of the order of 100 kGy, which proves their good performance at relatively lower doses.
Par exemple, préalablement à ladite exposition audit rayonnement ionisant, les emballages sont montés sur des supports, par exemple sur des palettes, et sont ensuite emballés dans un film de polyéthylène, assurant la protection de leur environnement qu'ils pourraient contaminer.For example, prior to said exposure to said ionizing radiation, the packages are mounted on supports, for example on pallets, and are then packaged in a polyethylene film, ensuring the protection of their environment that they could contaminate.
