Comprehensive microbiological evaluation of dry foods for growing dogs marketed in Poland. Microbiological safety is one of the most important parts of qualitative assessment and monitoring of commercially available products intended for canine nutrition. Twenty commercial dry dog foods formulated for growing dogs were surveyed for the prevalence of bacterial contamination. ISO standards were applied to assess total plate counts of mesophilic strains, yeasts and molds, Enterobacteriaceae family andEnterococcus. Moreover, the presence of major pathogenic bacteria was evaluated. The growth of molds was detected in 5 products. Enterobacteriaceae strains were identified in 12 examined foods. Escherichia coli was identified in 4 samples. Half of the analyzed foods showed apparent presence of enterococci. All analyzed samples were free from Staphylococcus, Salmonella and Listeria spp. contamination. During microscopic confirmation of suspicious colonies Bacillus spp. were identified in 7 products. The results of our pilot study allowed to conclude that the principles of good manufacturing practice and hygienic regime were generally respected during factory processing, resulting ina relative low risk, with a clear necessity for continued control.

A survey of Deoxynivalenol and Zearalenone content in commercial dry foods for growing dogs. The Polish market of commercial dry dog food for growing dogs of small breeds was surveyed for the presence of DON and ZEN with its metabolites α- and β-zearalenol (α-, β-ZOL). LC/ /MS method was applied for 6 randomly selected foods. The low levels of toxins found, gives overall picture of the safe segment of the market. The content of masked α-zearalenol, however, from the perspective of long term consumption of small amounts may pose a health risk for the reproductive system of bitches.

Quantity and quality of fat in every day diet influence human health. Recently particular attention is payed to trans fatty acids composition in ingested food. Modern, no time consuming, convenient food is widely used now. Seventeen chosen products like dry soups or sauces mixes from the market in Poland were analysed to estimate fat concentration and fatty acids composition including trans fatty acids. The products contained different amount of fat, from about 3g/100g to 24g/100g of product. The fat concentration as well as fatty acids composition varied dependently on the kind of product and producer too. The dominated group of fatty acids in all analysed samples were saturated fatty acids (up to 50%). Monounsaturated fatty acids occured in the range from 15 to 40%, while polyansaturated from 2 to 6%. Four trans fatty acids were identified: 18:1, 6-trans, 18:1, 9-trans, 18:1, 12-trans, and 18:2, cis-9, trans-12. Only 18:1, 9-trans.

The objective of this study was to compare the content of selected complete dry feed labels for adult, healthy dogs and cats, emphasizing the accordance with the relevant EU requirements which have recently came into force. Additionally, simple calculations of the energy content were made to enhance the characteristics of the products available to the customer. The level of accordance reached in average 87% and 82% in dog and cat food respectively. It should be stated that the improvement of the labels content, as compared with 2011, was not signiﬁcant. The key elements of the label information were either not improved or decreased (the statement of the necessity of constant access to water or daily dosage per animal). All evaluated products were typical maintenance foods, but their energy density was quite differentiated which may have some deleterious nutritional consequences associated with their long time supply.
