“…This result correlates with the findings from the ENERGY study (which examines health in children across seven European countries) in which extremely high soft drink consumption amongst Dutch children was reported [20]. Furthermore, soft drink consumption in the Netherlands has increased by 74% between 1980 and 2009 [56]. In the North American supermarkets audited, shelf space devoted to soft drinks and potato chips was greater than for confectionery and chocolate in comparison with the other countries assessed.…”

BackgroundCross-country differences in dietary behaviours and obesity rates have been previously reported. Consumption of energy-dense snack foods and soft drinks are implicated as contributing to weight gain, however little is known about how the availability of these items within supermarkets varies internationally. This study assessed variations in the display of snack foods and soft drinks within a sample of supermarkets across eight countries.MethodsWithin-store audits were used to evaluate and compare the availability of potato chips (crisps), chocolate, confectionery and soft drinks. Displays measured included shelf length and the proportion of checkouts and end-of-aisle displays containing these products. Audits were conducted in a convenience sample of 170 supermarkets across eight developed nations (Australia, Canada, Denmark, Netherlands, New Zealand, Sweden, United Kingdom (UK), and United States of America (US)).ResultsThe mean total aisle length of snack foods (adjusted for store size) was greatest in supermarkets from the UK (56.4 m) and lowest in New Zealand (21.7 m). When assessed by individual item, the greatest aisle length devoted to chips, chocolate and confectionery was found in UK supermarkets while the greatest aisle length dedicated to soft drinks was in Australian supermarkets. Only stores from the Netherlands (41%) had less than 70% of checkouts featuring displays of snack foods or soft drinks.ConclusionWhilst between-country variations were observed, overall results indicate high levels of snack food and soft drinks displays within supermarkets across the eight countries. Exposure to snack foods is largely unavoidable within supermarkets, increasing the likelihood of purchases and particularly those made impulsively.

“…The results are somehow consistent with the findings of Brandhoff et al (2016) , who reported that different food samples, including dairy and meat, were subjected to the analysis of selected radionuclides in meat but are less than the acceptable limit. The results were further supported by the findings of Miyazaki et al (2013) who depicted that about 300 samples were determined for the presence of radioactive iodine ( 131 I) and cesium ( 137 Cs and 134 Cs) and it was found that only few samples showed some contamination, but below the regulatory limits.…”

Animal-origin food products pose serious threat to public food safety due to high microbial loads. The microbial and radioactive contaminations in commercial cold duck meat products were evaluated. Ten different lots of commercial samples (C1-C10) were classified based on type and smoking process. All samples were highly contaminated (< 4-7 Log CFU/g) with total aerobic bacteria (TAB), yeasts and molds (Y&M), and 7 samples (C1-C7) were positive for coliforms. Furthermore, three samples were contaminated with Listeria monocytogenes (C4-C6) and one with Salmonella typhimurium (C6). No radionuclides (131I, 137Cs, and 134Cs) were detected in any sample. The results of DEFT (direct epifluorescent filter technique)/APC (aerobic plate count), employed to screen pre-pasteurization treatments of products, indicated that smoked samples were positive showing DEFT/APC ratios higher than 4. Notably, the samples showed a serious threat to microbial safety, thus were irradiated with electron-beam (e-beam). The D10 values for S. typhimurium and L. monocytogenes were 0.65 and 0.42 kGy, respectively. E-beam application at 3 and 7 kGy resulted in reduction of initial TAB, Y&M, and coliform populations by 3 and 6 log cycles, respectively. Thus, e-beam was proven to be a good decontamination approach to improve the hygiene of cold duck meat.

Milk consumption is a subject of many opposing opinions, regarding its epigenetic influence on genomic and proteomic cell events, what may change inflammatory, metabolic, oxidative and neurocognitive function. For some of milk ingredients, such as saturated lipids, lactose and some casein forms, the pathogenetic mechanisms were documented. Certain products, including some enzymes, low-weight partially digested peptides and non-protein nitrogen compounds, are still in the serious observations. To avoid "unwanted" compounds is complex, because of different conditions of their appearance, what in some extent determines if they can be avoided in pre-dairy manufacturing or eliminated in a dairy manufacturing and post-dairy processing and packing. Pre-dairy manufacturing should represent new approaches toward genetic selections of dairy breeds regarding milk biochemical composition (β-caseins). A number of contaminants, from pesticides to drugs, toxins, hormones, heavy metals, pharmaceuticals, phthalates, carcinogens, synthetic chemicals, or veterinary drugs may appear in a pre-dairy process through the plant material (forage) or artificially via (uncontrolled) cattle treatment. A proper growing and planting conditions, antifungal chemical treatment or dry collection of feedstuffs, or destruction of mycotoxins by biodegradation process may decrease their content. Unwanted compounds of milk, which may be eliminated during dairy manufacturing and packing, may be xanthine oxidase, uric acid, saturated fats and lactose. Beside low fat milk production, the quality improvement in milk fatty acids composition can be achieved by changing the animal feeding type. Regarding lactose or its components, glucose and galactose, it should be clearly distinguished the sugar-free milk from milk containing digested lactose, on the pack nutrition label. The main contaminants which appear, because of dairy products packing in plastic bottles and cups, are phthalates. Good agricultural practices (GAPs) concerning dairy industry should be directed to integrate different preventive strategies and to satisfy personalized nutrition concept.
