The occurrence and antimicrobial susceptibility of salmonellae isolated from commercially available canine Raw Food diets in three Canadian cities.
Zoonoses and Public Health, 2008Co-Authors: Rita Finley, Meredith Vandermeer, Richard J. Reid-smith, C. Ribble, M. Popa, Jeff AraminiAbstract:Summary The purpose of the present study was to evaluate the prevalence and antimicrobial resistance patterns of Salmonella isolated from commercially available canine Raw Food diets in Canada. A total of 166 commercial frozen Raw Food diet samples were purchased from randomly selected local pet stores in three Canadian cities for a period of 8 months. All samples were evaluated for the presence of Salmonella, serotyped and tested for antimicrobial susceptibility. There was an overall Salmonella prevalence of 21%; chicken was an ingredient for 67% of the Salmonella-positive diets. Eighteen different Salmonella serotypes were recovered, and resistance was observed to 12 of the 16 antimicrobials tested, with the majority of Ontario isolates exhibiting resistance to ampicillin and Calgary isolates to tetracycline. This study demonstrates the potential risk of Raw Food diets, especially for immunocompromised individuals, and stresses the need for implementing regulatory guidelines for the production of these diets in order to help control and ideally eliminate the bacterial risks associated with their use and consumption.

The Risk of Salmonellae Shedding by Dogs Fed Salmonella-contaminated Commercial Raw Food Diets
The Canadian veterinary journal = La revue veterinaire canadienne, 2007Co-Authors: Rita Finley, Jeff Aramini, Meredith Vandermeer, C. Ribble, Maria Popa, Marcus Litman, Richard J. Reid-smithAbstract:Twenty-eight research dogs were enrolled to determine the prevalence of salmonellae shedding after consumption of 1 Salmonella-contaminated commercial Raw Food diet meal. Sixteen dogs were exposed to Salmonella-contaminated commercial Raw Food diets and 12 to Salmonella-free commercial Raw Food diets. Seven of the exposed dogs shed salmonellae 1–7 days after consumption of Salmonella-contaminated Raw Food diets. None of the dogs fed Salmonella-free diets shed salmonellae. No clinical signs were observed in either group. Five of the 7 dogs shed the same serotypes as those recovered from Food samples used for feeding. Results showed the same serotypes and antimicrobial resistance pattern in 2 of the 7 shedders. Dogs fed Salmonella-contaminated Raw Food diets can shed salmonellae and may, therefore, be a source of environmental contamination potentially leading to human or animal illness.

Human Health Implications of Salmonella-Contaminated Natural Pet Treats and Raw Pet Food
Clinical Infectious Diseases, 2006Co-Authors: Rita Finley, Richard J. Reid-smith, J. Scott Weese, Frederick J. AnguloAbstract:Human salmonellosis occurs mainly as a result of handling or consuming contaminated Food products, with a small percentage of cases being related to other, less well-defined exposures, such as contact with companion animals and natural pet treats. The increasing popularity of Raw Food diets for companion animals is another potential pet-associated source of Salmonella organisms; however, no confirmed cases of human salmonellosis have been associated with these diets. Pets that consume contaminated pet treats and Raw Food diets can be colonized with Salmonella organisms without exhibiting clinical signs, making them a possible hidden source of contamination in the household. Pet owners can reduce their risk of acquiring Salmonella organisms by not feeding natural pet treats and Raw Food diets to their pets, whereas individuals who investigate cases of salmonellosis or interpret surveillance data should be aware of these possible sources of Salmonella organisms.

dietary influence on urinary excretion of 3 deoxyglucosone and its metabolite 3 deoxyfructose
Journal of Agricultural and Food Chemistry, 2014Co-Authors: Julia Degen, Helene Beyer, Bjoern Heymann, Michael Hellwig, Thomas HenleAbstract:3-Deoxyglucosone (3-DG), a reactive 1,2-dicarbonyl compound derived from d-glucose in Food and in vivo, is an important precursor for advanced glycation endproducts (AGEs). At present, virtually no information about the metabolic transit of dietary 3-DG is available. One possible metabolic pathway of 3-DG during digestion is enzymatic transformation to less reactive compounds such as 3-deoxyfructose (3-DF). To study the handling of dietary 1,2-dicarbonyl compounds by the human body, 24 h urinary excretion of 3-DG and its metabolite, 3-deoxyfructose, was investigated. Urinary 3-DG and 3-DF excretion was monitored for nine healthy volunteers following either a diet with no dietary restrictions or a diet avoiding the ingestion of 3-DG and other Maillard reaction products (“Raw Food” diet). During the “Raw Food” diet, the urinary 3-DG and 3-DF excretion decreased approximately to 50% compared to the excretions during the diet with no restrictions. When subjects received a single dose of wild honey (50 g) natu...

During the “Raw Food” diet, the urinary 3-DG and 3-DF excretion decreased approximately to 50% compared to the excretions during the diet with no restrictions. When subjects received a single dose of wild honey (50 g) naturally containing a defined amount of 3-DG (505 μmol), median excretion of 3-DG and 3-DF increased significantly from 4.6 and 77 to 7.5 and 147 μmol/day, respectively. The obtained experimental data for the first time demonstrate a dietary influence on urinary 3-DG and 3-DF levels in healthy human subjects

long term strict Raw Food diet is associated with favourable plasma β carotene and low plasma lycopene concentrations in germans
British Journal of Nutrition, 2008Co-Authors: Ada L. Garcia, Pieter C Dagnelie, Corinna Koebnick, Carola Strassner, Norbert Katz, Claus Leitzmann, Ibrahim Elmadfa, Ingrid HoffmannAbstract:Dietary carotenoids are associated with a reduced risk of chronic diseases. Raw Food diets are predominantly plant-based diets that are practised with the intention of preventing chronic diseases by virtue of their high content of beneficial nutritive substances such as carotenoids. However, the benefit of a long-term adherence to these diets is controversial since little is known about their adequacy. Therefore, we investigated vitamin A and carotenoid status and related Food sources in Raw Food diet adherents in Germany. Dietary vitamin A, carotenoid intake, plasma retinol and plasma carotenoids were determined in 198 (ninety-two male and 106 female) strict Raw Food diet adherents in a cross-sectional study. Raw Food diet adherents consumed on average 95 weight% of their total Food intake as Raw Food (approximately 1800 g/d), mainly fruits. Raw Food diet adherents had an intake of 1301 retinol activity equivalents/d and 16·7 mg/d carotenoids. Plasma vitamin A status was normal in 82 % of the subjects ( ≥ 1·05 μmol/l) and 63 % had β-carotene concentrations associated with chronic disease prevention ( ≥ 0·88 μmol/l). In 77 % of subjects the lycopene status was below the reference values for average healthy populations ( r 0·284; P r 0·168; P = 0·024). Long-term Raw Food diet adherents showed normal vitamin A status and achieve favourable plasma β-carotene concentrations as recommended for chronic disease prevention, but showed low plasma lycopene levels. Plasma carotenoids in Raw Food adherents are predicted mainly by fat intake.

long term consumption of a Raw Food diet is associated with favorable serum ldl cholesterol and triglycerides but also with elevated plasma homocysteine and low serum hdl cholesterol in humans
Journal of Nutrition, 2005Co-Authors: Corinna Koebnick, Pieter C Dagnelie, Carola Strassner, Norbert Katz, Claus Leitzmann, Jan Lindemans, Ada L. Garcia, Ingrid HoffmannAbstract:High consumption of vegetables and fruits is associated with reduced risk for cardiovascular disease. However, little information is available about diets based predominantly on consumption of fruits and their health consequences. We investigated the effects of an extremely high dietary intake of Raw vegetables and fruits (70-100% Raw Food) on serum lipids and plasma vitamin B-12, folate, and total homocysteine (tHcy). In a cross-sectional study, the lipid, folate, vitamin B-12, and tHcy status of 201 adherents to a Raw Food diet (94 men and 107 women) were examined. The participants consumed approximately 1500-1800 g Raw Food of plant origin/d mainly as vegetables or fruits. Of the participants, 14% had high serum LDL cholesterol concentrations, 46% had low serum HDL cholesterol, and none had high triglycerides. Of Raw Food consumers, 38% were vitamin B-12 deficient, whereas 12% had an increased mean corpuscular volume (MCV). Plasma tHcy concentrations were correlated with plasma vitamin B-12 concentrations (r = -0.450, P < 0.001), but not with plasma folate. Plasma tHcy and MCV concentrations were higher in those in the lowest quintile of consumption of Food of animal origin (P(trend) < 0.001). This study indicates that consumption of a strict Raw Food diet lowers plasma total cholesterol and triglyceride concentrations, but also lowers serum HDL cholesterol and increases tHcy concentrations due to vitamin B-12 deficiency.

The Risk of Salmonellae Shedding by Dogs Fed Salmonella-contaminated Commercial Raw Food Diets
The Canadian veterinary journal = La revue veterinaire canadienne, 2007Co-Authors: Rita Finley, Jeff Aramini, Meredith Vandermeer, C. Ribble, Maria Popa, Marcus Litman, Richard J. Reid-smithAbstract:Twenty-eight research dogs were enrolled to determine the prevalence of salmonellae shedding after consumption of 1 Salmonella-contaminated commercial Raw Food diet meal. Sixteen dogs were exposed to Salmonella-contaminated commercial Raw Food diets and 12 to Salmonella-free commercial Raw Food diets. Seven of the exposed dogs shed salmonellae 1–7 days after consumption of Salmonella-contaminated Raw Food diets. None of the dogs fed Salmonella-free diets shed salmonellae. No clinical signs were observed in either group. Five of the 7 dogs shed the same serotypes as those recovered from Food samples used for feeding. Results showed the same serotypes and antimicrobial resistance pattern in 2 of the 7 shedders. Dogs fed Salmonella-contaminated Raw Food diets can shed salmonellae and may, therefore, be a source of environmental contamination potentially leading to human or animal illness.
