Mikrobiální kontaminace masa používaného ke krmení psů a koček v rámci syrové diety
HOSNEDLOVÁ, Barbora
Raw feeding, also called BAFR diet, is the practice of feeding a diet consisting of raw meat, offal and side dishes. The goals of the thesis were (i) to utilize a question-naire survey among breeders practicing the BARF diet (307 responders) to obtain further information about their motivation for practicing this diet, type of meat used and its treatment, and (ii) to microbiologically analyze two kinds (chicken, beef) of raw meat during the three days of its storing. It has been found that the main reason for practicing the BARF diet is that it's more natural and healthier for the animals according to the owners. The responders prefer frozen meat (87%) that they store in the refrigerator prior to consumption and keep it there for up to 3 days. The most commonly used types of meat are beef and poultry (55%). More than a half (58%) of the responders use the same tools for both preparing the feed dose as well as for preparing the meals for their household. The microbiological analysis of the meat confirmed an increase in the total number of microorganism and the number of coli-form bacteria during the three days of storage in the refrigerator - in chicken meat this increase was from 6.3 KTJ/g, respectively 4.8 KTJ/g (1st day) to 8.3 KTJ/g, respectively 6.4 KTJ/g (last day), for beef from 6.5 KTJ/g, respectively 4.3 KTJ/g (1st day) to 8.3 KTJ/g, respectively 5.5 KTJ/g (last day). A significant increase in number of microorganisms, some of which may cause human diseases, occurs while the feed meat is being stored in a refrigerator for a usual amount of time. It is therefore necessary to appeal for more hygienic manipu-lation when practicing this type of diet, which is also related to raising the pet own-ers' awareness of this issue.
