中国上海即食牛肉制品微生物污染情况的随机研究

本文研究了上海即食牛肉样品中微生物的污染情况。从上海的5个国际超市和5个街头摊贩随机抽取20份即食牛肉样品,采用培养法分析样本的菌落总数,并从每份样品中随机抽取10个菌落采用16S rRNA基因测序法对细菌进行分类鉴定。超市牛肉样本的菌落总数平均为(1.08±1.73)×108 CFU/g,街头摊贩样本菌落总数平均为(2.84±8.49)×108 CFU/g,二者在统计学上无显著性差异（p>0.05）,但均高于国家标准（≤8×104 CFU/g）。所有样本均未检出能引起严重食物中毒的病原体,但检测到种类多样且与食物中毒、尿路感染、肺炎、乳腺炎以及菌血症等疾病相关的多种病原菌操作分类单元（OTU）。结果表明,即食食物是一个经常被忽视的致病微生物的储存库,我国应加强对即食食物的卫生管理,从而降低即食食品引起的食源性疾病传播几率。

Potential risk and sodium content of children’s ready-to-eat foods distributed at major amusement parks in Korea

This study was conducted to help better understand the current sodium intake of Korean children and to establish children’s good eating habits through investigation of the sodium content of ready-to-eat foods collected from nine major amusement parks in Korea. The sodium content of a total of 322 products was analysed by using ICP and then the potential risk based on the recommended daily intake of sodium as described in the Korean dietary reference intakes was determined. The results showed that sodium content was the lowest in muffins (245 mg/100 g) and the highest in seasoned dried filefish (1825 mg/100 g). The average amounts of sodium per serving of seasoned dried filefish, tteokbokki and fish paste were 1150, 1248 and 1097 mg, respectively. The values were above 50% of the daily intake of sodium recommended by the Korean dietary reference intake. The ready-to-eat foods were also classified into high, medium and low sodium content on the basis of standards recommended by the Korean Food and Drug Administration. Most snacks were classified as high sodium foods because they exceeded “300 mg (84.5% of the total daily allowance)”. Furthermore, the meal substitution foods such as kimbab, tteokbokki, mandus, sandwiches and hamburgers exceeded “600 mg (90.3% of the total daily allowance)” and were also classified as high sodium foods. In addition, ready-to-eat foods in amusement parks are similar to foods eaten on streets and foods around school zones, which contain high sodium content; thus, the intake frequency might be high, which would induce high risk to children health. Koreans already consume a high amount of sodium daily via their usual diets. So, the sodium content in snacks and substitution foods needs to be reduced. Consequently, this study noted that parents and guardians should carefully consider their children’s consumption of ready-to-eat foods from Korean amusement parks.     

Effect of a health reminder on consumers’ selection of ultra-processed foods in a supermarket

Consumers report difficulties when trying to make healthy food choices in supermarkets due to environmental cues that favour the acquisition of unhealthy food items. This study’s objective was to investigate food selection in a supermarket to prepare a last minute meal by consumers with different levels of health consciousness. In an experimental design, 50 high (HHC) and 50 low health conscious (LHC) participants (n = 100) were told to choose all food items to prepare a meal for themselves plus a guest. For half the participants (25 HHC and 25 LHC), the expression ‘healthy meal’ was embedded in the instruction. To evaluate shopping healthfulness, foods selected by the participants were categorized according to level of industrial processing in Unprocessed/Minimally Processed (U/MP); Processed Culinary Ingredient (PCI); Processed (P), or Ultra-Processed (UP). The health reminder positively affected the choices of HHC and LHC individuals. Results indicate that placing reminders of healthy eating in shopping environments where P and UP foods sales are heavily promoted, such as supermarkets, can be a useful tool to promote healthy choices in accordance with what is recommended by the Dietary Guidelines for the Brazilian Population.
