" Niet alles gaat over wormen maar in het algemeen risico's bij vers voeren. In het algemeen komt het erop neer welke diersoorten je voert, hoe hygiënisch het dier geslacht werd en hoe jij zelf omgaat met het vlees.

Ontwormingsfrequentie bij de hondIn Zwitserland is gekeken naar de prevalentie van maag-darmparasieten bij de hond, eventuele risicofactoren en de invloed van de ontwormingsfrequentie. Van meer dan vijfhonderd honden werd bij 7 procent een Toxocara canis-infectie aangetroffen, een haakworminfectie bij 7 procent en een Trichuris vulpis-infectie bij 5,5 procent. Er werd geen invloed gevonden van coprofagie (eten van poep bij een kwart van de honden aanwezig), de aard van de voeding (rauw vlees, tafelresten of commerciële voeding) en ook was er geen verschil tussen boerderij- en stadshonden.
Wel bleek dat het aantal besmette dieren significant afnam bij een ontwormingsfrequentie van vier of twaalf keer per jaar (respectievelijk met Drontal® en Milbemax®
.
Driemaandelijks ontwormen is echter geen garantie dat de dieren helemaal vrij van wormen blijven. Sommige honden bleken zichzelf namelijk tussen de behandelingen door nog te kunnen besmetten en voor een volgende behandeling weer eieren uit te scheiden.
Uit een ander onderzoek bleek dat het ontwormen van jonge besmette honden een positieve invloed had op het induceren van leeftijdsresistentie tegen T. canis. Dat wil zeggen dat bij herbesmetting significant minder dieren eieren gingen uitscheiden (minder besmetting van de omgeving). Ook dit is een goede reden om het ontwormen van pups te stimuleren.

This preliminary study found that 30% of stool samples from dogs fed homemade BARF diets contained various Salmonella serovars, whereas none of the samples from dogs fed commercial dry diets containedSalmonella spp.
Although these results are suggestive, they are not statistically significant owing to the small number of dogs studied. Larger numbers of dogs or multiple stool samples from each dog might have allowed the results to reach statistical significance. Unfortunately, the limited funding to this private clinic for this study did not allow for the inclusion of more study animals or multiple cultures from individual subjects.
Though interesting, the fact that 80% of BARF food samples cultured positive for Salmonella spp. is not surprising, given the well-documented prevalence of Salmonella spp. in raw chicken (3). The fact that none of the commercial food samples cultured positive for Salmonella spp. was not unexpected.
The results of this preliminary study prove that some dogs fed a BARF diet shed Salmonella spp. in their stools.
This fact should be a consideration for owners choosing to feed this diet and be of especial concern for those with young children, the aged, or other people who may have compromised immune systems. We hope that this study will serve as an impetus for further study, with more subjects and multiple stool samples from each subject, to fully elucidate the public health concerns of this popular feeding trend. Given the high percentage of BARF diets that were positive for Salmonella spp. on culture, strict hygiene must be implemented when handling this food. In addition, the food bowl, the feeding area, and the pet's mouth must be considered as potential sources of Salmonella.

This study explored the impact of feeding raw meat to dogs on the fecal prevalence of several enteric bacterial zoonotic pathogens.
Campylobacter jejuni was isolated from 1/42 (2.6%) raw meat-fed dogs.
Salmonella enterica was isolated from 2/40 (5%) of the raw meat feeds, 6/42 (14%) raw meat-fed dog feces, none of the dogs that did not receive raw meat (P = 0.001), 4/38 (10.5%) of the vacuum cleaner waste samples from households where raw meat was fed, and 2/44 (4.5%) of vacuum cleaner waste samples from households where raw meat was not fed to dogs (P = 0.41).
Responses to a questionnaire probing practices and beliefs regarding raw meat feeding that was administered to dog owners demonstrated that dog owners may either not be aware or refuse to acknowledge the risks associated with raw meat-feeding; thus, they may neglect to conduct adequate intervention strategies to prevent zoonoses among themselves and their families.
In this study, although dogs that were fed raw meat were more likely to shed Salmonella in their feces than dogs that were not, Salmonella may contaminate the household environment and serve as a source ofSalmonella exposure to humans in households with dogs, regardless of the diet fed. Human exposure toSalmonella-positive dogs and contaminated household environments has public health implications, particularly for the very young, the elderly, pregnant women, and otherwise immunocompromised individuals.
The frequency of food contamination can be influenced by the feed ingredients, the prevalence of the pathogens in the live animals at the time of slaughter, and the degree of hygiene during processing, transportation, and storage. Certain meat products are more likely than others to be contaminated with specific pathogens. For example, at slaughter, E. coli O157 is most likely to contaminate foods of bovine origin and not other meats (17). Therefore, exclusion of beef products from raw meat diets for dogs will reduce the likelihood of this organism in the feed.
Furthermore, there are seasonal variations in carriage rates and contamination rates of several foodborne pathogens by food-producing animals (18,19,20) Prevalence is highest in cattle in the summer for E. coliO157, Salmonella, and Campylobacter (18,19). Likewise, the prevalence of Campylobacter spp. in poultry also increases in the warmer months (21). The frequency of pathogen contamination of meats intended for human consumption has decreased in recent years. Nevertheless, approximately 0.17% of ground beef samples test positive for E. coli O157 (22) and as many as 25% and 80% of poultry samples test positive forSalmonella spp. and Campylobacter spp. respectively, depending upon the source (20). In summary, pathogen contamination in raw meats, even those intended for human consumption, occurs. Sixty percent of raw meat commercially available for dog foods are contaminated with generic E. coli, indicating that microbial contamination of these products at the time of either slaughter or processing is common (6). The frequency of Salmonella contamination of raw-meat diets found in this study was similar to that in other reports (5,6,8).
Heb hier zelf geen mening over eigenlijk, ik ontworm regelmatig en mijn honden krijgen door hun jeuk sowieso al geen kip of rund...
