Detection of Adenovirus in Fresh Fruit, Vegetables, Wastewater and Manure from Irrigated Farms in Ouagadougou, Burkina Faso

Enteric viral pathogens are responsible for numerous epidemics associated with the consumption of fresh fruit and vegetable, whether raw or minimally processed. The aim of the present study was to assess agricultural practices and the presence of adenovirus (AdV) in fruits and vegetables, manure and irrigation wastewater sampled in the urban and peri-urban perimeters of Ouagadougou. A total of 286 samples including 30 lettuces, 42 tomatoes, 30 carrots, 30 strawberries, 74 manures and 80 wastewater samples were collected from four market garden sites in and around Ouagadougou. Nested PCR was performed with specific primers to detect adenoviruses (AdVs). A face-to-face survey was carried out using a questionnaire on market garden production practices. Overall, adenoviruses prevalence was 5.9% [IC95, 3.2% - 8.7%] in all samples analyzed. It was specifically 7.14% (3/42) from tomatoes, 6.7% (2/30) from lettuces, 20% (6/30) on strawberries and 7.5% (6/80) in irrigation water. The survey showed that irrigation water came from untreated sources (dam, well, canal) and then 52% of farms used untreated manure. No farms have implemented measures to limit access by domestic and wild animals. This work shows the presence of human adenoviruses in surface irrigation water and fresh produce, which is of concern when fresh produce is consumed raw. To reduce the public health risks associated with consuming these foods, it is essential to follow good hygiene and cultivation practices.

Attributable Causes of Cancer in China:Fruit and Vegetable

Objective：To provide an evidence-based and consistent assessment of the burden of cancer attributable to inadequate fruit and vegetable intake in China in 2005.Methods：The proportions of cancers attributable to low consumption of vegetable and fruit were calculated separately to estimate the burden of related cancers for the year 2005 in China.Data on the prevalence of exposure were derived from a Chinese nutrition and health survey.Data on relative risks were mainly derived from meta-analysis.Attributable fractions were calculated based on the counterfactual scenario which was a shift in the exposure distribution.Results：The total cancer burden attributable to inadequate consumption of fruit was up to 233,000 deaths （13.0% of all cancers） and 300,000 cases （11.6% of all cancers） in 2005.Increasing consumption of vegetable to the highest quintile could avoid total cancer deaths and cases by 3.6% （64,000 persons） and 3.4% （88,000 persons）.The contributions to cancer burden were higher in rural areas than in urban areas.They have greater influence on men than on women.The largest proportions of cancer burden attributable to low fruit and vegetable intake were for oral and pharyngeal cancers.Conclusion：This study showed that inadequate intake of fruit and vegetable makes a significant contribution to the cancer burden.Increasing consumption of fruit and vegetable could prevent many cancer deaths and save many lives.Promoting the consumption of fruit and vegetable is an important component in diet-based strategies for preventing cancer.

Fruit and vegetable consumption and its relation to risk of asthenopia among Chinese college students

AIM： To investigate the associations between fruit and vegetable consumption and risk of asthenopia among Chinese college students. METHODS： A total of 1022 students were selected from five universities by a multi-stage stratified cluster sampling method. They were surveyed via a self-administered questionnaire including socio-demographic features, dietary and lifestyle habits, eye-related symptoms, eye care habits and history of diseases. Ascertainment of asthenopia was based on participants＇ subjectively reported symptoms. The associations between fruit and vegetable intake with asthenopia risk were assessed using multivariate logistic regression analysis. RESULTS： There were no significant associations between total fruit and vegetable, total vegetable, or fruit and the risk of asthenopia. Higher intake of dark-green leafy vegetable was likely to be inversely associated with asthenopia risk [odd ratio （OR）： 0.60; 95%CI： 0.37-0.97; Ptrend=0.21] after controlling for nondietary and dietary risk factors. Stratified analysis showed that the inverse association between dark-green leafy vegetable intake and asthenopia risk was limited to participants with suboptimal eyesight （OR： 0.45; 95%CI： 0.25-0.82; Ptrend=0.05）, wearing glasses （OR： 0.35; 95%CI： 0.17-0.72; Ptrend=0.03） or using computer ≥3h/d （OR： 0.48; 95%CI： 0.25-0.93; Ptrend=0.08）. CONCLUSION： A higher consumption of dark-green leafy vegetable is associated with a lower asthenopia risk among college students with suboptimal eyesight and poor eye care habits.

Contents of Phytosterols in Vegetables and Fruits Commonly Consumed in China

Objective To quantify five specific dietary phytosterols and phytostanols in vegetables and fruits commonly consumed in China. Methods A total of 34 different kinds of vegetables and 33 kinds of fruits were chosen according to the consuming habit of Chinese people. All the samples were purchased from two shops in Beijing. The contents of phytosterols （13-sitosterol, campesterol, stigmasterol, 13-sitostanol, and campestanol） were analyzed by GLC method which was established by our laboratory, and the total phytosterols were calculated. Results The total phytosterol content in vegetables ranged 1.1-53.7 mg/100 g edible portion. The highest concentration was found in pea, cauliflower, broccoli, and romaine lettuce. The phytosterol contents in fruits ranged 1.6-32.6 mg/100 g, the highest concentration was found in navel orange, tangerine, and mango. Conclusion The phytosterol contents in vegetables and fruits are not as high as those in edible oils, but because of the large amount of consumption, they also play an important role in increasing the people＇s phytosterols intake, indicating that increased intake of vegetables and fruits with higher phytosterol contents helps increase the phytosterol intake in China.

Simultaneous Screening of 733 Pesticide Residues in Fruits and Vegetables by a GC/LC-Q-TOFMS Combination Technique

In this paper,we report the construction of two accurate mass databases and the development of a combination detection method that simultaneously screens for 733 pesticide and chemical contaminant multi-residues via high-throughput liquid chromatography(LC)-and gas chromatography(GC)-quadru pole-time-of-flight mass spectrometry(Q-TOFMS).This work demonstrates that electronic mass spectral standards may replace chemical-source standard materials as references through one sample preparation and the combination of GC/LC-Q-TOFMS screening.This cutting-edge technique has also replaced multiresidue determination using targeted detection with non-targeted screening.The pesticide residue types,sensitivity,recovery,and reproducibility of this combination technique are evaluated in eight fruit and vegetable matrices.This technique shows three advantages:①In comparison with the discovery capability of a single technique,the combination technique shows an improvement of 51.1%(GC-QTOFMS)and 39.6%(LC-Q-TOFMS),respectively;②the combination technique can satisfy a screening limit lower than 10μg·kg^-1 and meet the requirements of“uniform standards,”although some of the pesticide residues could be optimized to further improve screening sensitivity;③over 488 pesticides with recoveries between 60%-120%and relative standard deviation(RSD)<20%at a spiked level of 10μg·kg^-1 were detected with the combination technique in eight different matrices.From 2012 to 2017,this combination technique was applied in an investigation to screen pesticide residues from 1384 sampling locations for 38138 batched samples covering 18 categories and 134 types of fruits and vegetables obtained from across the mainland of China.After statistical analysis,533 pesticides in 115891 determinations were detected,and the regularity of pesticides in the fruits and vegetables sold on the Chinese market was shown.

Influence of Probiotic Fermented Fruit and Vegetables on Human Health and the Related Industrial Development Trend

The paper briefly discusses the relationship between chronic diseases and gut health,and points out that an imbalance of intestinal microflora and an inadequate intake of dietary fiber are two important causes of chronic diseases.This paper also summarizes the research status of probiotic fermented fruit and vegetables,and discusses the main achievements of our group in this field and future developments of the related industry.The application of fermentation technology to fruit and vegetable processing and the development of a series of probiotic fermented fruit and vegetable products not only increase the added value of fruit and vegetables,but also organically combine probiotics and their active metabolites with prebiotics(dietary fiber,etc.),thereby promoting intestinal health as well as preventing and relieving chronic diseases.Fermentation technology provides a new approach to the study of the effect of probiotics on human health,and will have a revolutionary influence on probiotic application and on the fruit and vegetable processing industry.Thus,fruit and vegetable fermentation technology has excellent market potential.

Vegetable and Fruit Consumption among Chinese Adults and Associated Factors： A Nationally Representative Study of 170,847 Adults

Objective This study examined vegetable and fruit （VF） consumption rate and its associated factors among Chinese adults. Methods Nationally representative data from the 2013 China Chronic Disease Surveillance survey were used. Dietary intake data, including VF consumption during the last 12 months, were collected. All analyses were weighted to obtain nationally representative estimates. Associations between VF consumption and other factors （e.g., meal frequency and physical activity） were examined through logistic regression analysis. Results The average fruit consumption was 102.3 g/day （95% CI： 97.0-107.6） and the average vegetable consumption was 350.6 g/day （95% CI： 339.3-361.8）. Over half （53.2%, 95% CI： 50.9-55.4） of Chinese adults met the VF consumption of 400 g/day recommended by the World Health Organization （WHO）. Rural residents had a higher prevalence of low VF consumption rate than urban residents [49.20% （95% CI： 46.2%-52.2%） vs. 44.0% （95% CI： 41.7%-46.3%） P 〈 0.01]. Old age （OR = 1.01, 95% CI： 1.00-1.01）, low educational level, low income, minority ethnicity （OR = 1.41, 95% CI： 1.15-1.74）, underweight （OR = 1.17, 95% CI： 1.03-1.33）, single marital status （OR = 1.20, 95% CI： 1.08-1.33）, low health literacy, irregular breakfast （OR = 1.20, 95% CI： 1.04-1.38） or lunch （OR = 1.58, 95% CI： 1.26-1.99） habits, and no leisure-time physical activity were associated with low VF consumption. Conclusion Only half of Chinese adults met the VF consumption recommended by the WHO. Low socio-economic status, irregular diet, and poor health literacy were likely associated with low VF consumption. National efforts and programs are needed to promote VF consumption.

Antioxidant Capacities and Main Reducing Substance Contents in 110 Fruits and Vegetables Eaten in China

The aim of this study was to screen strongly-antioxidant fruits and vegetables and supply practical diet guidance for the public. We used 1,1-diphenyl-2-picrylhydrazyl (DPPH), ferric-reducing antioxidant potential (FRAP), 2,2’-azino-bis-3-ethylbenzthiazoline-6-sulphonic acid (ABTS) and total reducing power (TRP) assays to investigate antioxidant activities in 110 fruits and vegetables. To analyze the correlation between antioxidant capacities and main reducing substance contents, total phenolic, flavonoid and vitamin C contents were assessed. The results showed great variation in antioxidant activity, and fifteen fruits and vegetables possessed the strongest antioxidant capacities: Toona sinensis, hawthorn, jujube, lotus root, persimmon, red plum, black plum, chilli pepper, star fruit, strawberry, blueberry, cherry, peach, pomegranate and great burdock. Total phenolic contents showed higher correlation with antioxidant capacity when using FRAP and TRP assays than when using the DPPH or ABTS assay. Phenolics and flavonoids, rather than vitamin C, contributed to antioxidant potential in most fruits and vegetables.

Rapid screening of 420 pesticide residues in fruits and vegetables using ultra high performance liquid chromatography combined with quadrupole-time of flight mass spectrometry

A new method for screening and identification 420 pesticide residues in fruits and vegetables by ultra-performance liquid chromatography coupled with quadrupole-time of flight mass spectrometry(UPLC-Q-TOF/MS)were developed.The samples were extracted with acetonitrile/acetic acid(99:1,V/V),and clean-up by SinChERS-Nano(single-step,cheap,effective,rugged,safe,nano)column,determined by UPLC-Q-TOF/MS.The accurate mass database and MS/MS database which contains 420 pesticides were established,the automatic retrieval of detection results was carried on according to the accurate mass,retention time,isotope ratio,ion fragment information,and so on.Method verification was performed on leeks samples.The results showed that 420 pesticides had good linearity in the range of 0.1-100μg/L,and the correlation coeffificients(R2)was greater than 0.990.The limits of detections(LODs)and limits of quantifications(LOQs)of 420 pesticides were in range of 0.05-2.0 and 0.1-5.0μg/L,respectively.The average spike recoveries at 3 levels were 70.1%to 119.7%,and the relative standard deviations(RSD)were lower than 20%(n=6).With this method,a survey of pesticide residues was conducted for 110 samples of 10 different fruits and vegetables,which provided scientific data for ensuring pesticide residue safety of the fruits and vegetables consumed daily by the public.This method was simple,sensitive and accurate,and could be used for rapid screening of 420 pesticide residues in fruits and vegetables.

Pesticide Residues and Government Regulation in China─Evidence from Pesticide Residues in Fruits and Vegetables

China is a big producer and exporter of fruits and vegetables,and pesticide residues are an important factor affecting the quality and safety of fruits and vegetables and their export trade.In this paper,we analyzed the pesticide residue data on fruits and vegetables in 32 major Chinese cities between 2012—2019,the export data of Chinese fruits and vegetables and the role of pesticides in foodborne diseases.The results showed that pesticide residues in fruits and vegetables(PRFV)partial excess of maximum residue standard(MRL)and residues of banned pesticide were still widespread in China.By comparing the standards of pesticide residues in the European Union and China and addressing the agricultural situation in China,this paper analyzed the main causes of PRFV in China and put forward some policy suggestions for strengthening government regulation of pesticide application in agricultural products.

Fruits and Vegetables Freshness Categorization Using Deep Learning

The nutritional value of perishable food items,such as fruits and vegetables,depends on their freshness levels.The existing approaches solve a binary class problem by classifying a known fruit\vegetable class into fresh or rotten only.We propose an automated fruits and vegetables categorization approach that first recognizes the class of object in an image and then categorizes that fruit or vegetable into one of the three categories:purefresh,medium-fresh,and rotten.We gathered a dataset comprising of 60K images of 11 fruits and vegetables,each is further divided into three categories of freshness,using hand-held cameras.The recognition and categorization of fruits and vegetables are performed through two deep learning models:Visual Geometry Group(VGG-16)and You Only Look Once(YOLO),and their results are compared.VGG-16 classifies fruits and vegetables and categorizes their freshness,while YOLO also localizes them within the image.Furthermore,we have developed an android based application that takes the image of the fruit or vegetable as input and returns its class label and its freshness degree.A comprehensive experimental evaluation of proposed approach demonstrates that the proposed approach can achieve a high accuracy and F1score on gathered FruitVeg Freshness dataset.The dataset is publicly available for further evaluation by the research community.

Analysis of the Influencing Factors and Key Driving Force concerning the Efficiency of Green Supply Chain of Fruits and Vegetables

Like the general green supply chain,the green supply chain of fruits and vegetables also requires low negative effects of the environment and high resource utilization rate,as well as the healthiness and freshness of fruits and vegetables.Currently,the level of development of the green supply chain of fruits and vegetables is low in China,and the freshness of fruits and vegetables can not be well maintained,so there is an urgent need to improve the operational efficiency of the green supply chain of fruits and vegetables.The operational efficiency of the green supply chain of fruits and vegetables is affected by many factors,and the most important factor is the incomplete consistency between the individual interests of supply chain members and the overall interests of supply chain.Therefore,the key driving force to improve the efficiency of green supply chain of fruits and vegetables is to build the scientific and rational collaborative decision-making mechanism of supply chain,in order to solve the problems concerning the green supply chain of fruits and vegetables,such as risk sharing,cost control and revenue allocation,thereby achieving the coordinated development of the green supply chain of fruits and vegetables.

Selected fermented indigenous vegetables and fruits from Malaysia as potential sources of natural probiotics for improving gut health

In the Peninsular Malaysia and Northern Borneo island of Malaysia, various rich indigenous leafy vegetables and fruits grow and contribute to the nutritional and dietary values of the population. They have high water contents, thus, naturally vulnerable to rapid food spoilage. Food preservation and processing play a vital role in the inhibition of food pathogens in fruits and vegetables that are prevalent in Malaysia. Lactic acid fermentation is generally a local-based bioprocess, among the oldest form and well-known for food-processing techniques among indigenous people there. The long shelf life of fermented vegetables and fruits improves their nutritional values and antioxidant potentials. Fermented leaves and vegetables can be utilized as a potential source of probiotics as they are host for several lactic acid bacteria such as Lactobacillus confusus, Weissella paramesenteroides, Enterococcus faecalis, Lactobacillus plantarum, Lactobacillus buchneri, Lactobacillus paracasei, Lactobacillus pentosus, Pediococcus acidilactici, Pediococcus pentosaceus and Leuconostoc mesenteroides. These strains may be more viable in metabolic systems whereby they can contribute to a substantial increase in essential biologically active element than industrial starter cultures. This review is aimed to address some essential fermented fruits and vegetables in Malaysia and their remarkable reputations as a potential sources of natural probiotics.

Studies on Fungi Responsible for the Spoilage/Deterioration of Some Edible Fruits and Vegetables

Investigation of fungi responsible for the post harvest deterioration of Lycopersicum esculentus (tomatoes), Elaeis guineensis (palm fruit), Ipomoea batatas (sweet potato), Solanum tuberosum (Irish potato), Musa sapientum (banana), Doucus carota (carrot), Musa paradisiaca (plantain), Carica papaya (pawpaw), Persea americana (Avocado pear), Citrullus lanatus (water-melon) and Capsicum chinense (fresh red pepper) from five different markets and farm lands in Enugu state, Nigeria was carried out. Healthy and diseased samples were collected from the selected markets/ farmlands. Fungal species found associated with the deterioration of the various fruits and vegetables tested included Mucor species (M. indicus, M. amphibiorum, M. racemosus and M. hiemalis), Rhizopus species (Rhizopus stolonifer, R. nigrican and R. oligosporus), Candida albicans, Aspergillus species (Aspergillus fumigatus, A. niger and A. flavus) and Penicillum species (P. oxalicum and P. chrysogenum) and Fusarium species (F. accuminatum, F. oxysporum, F. eqiuseti and F. moniliforme, F. solani, F. dimerum). All isolated fungi were pathogenic to the different fruits and vegetables from the result of pathogencity tests carried out.

Relations of change in fruit and vegetable intake with overall energy reduction and physical activity with weight change:Assessing theory-based psychosocial mediators

Background'.Increased physical activity and fruit and vegetable(FV)intake are typically suggested to counter obesity.Sustained behavior change in those areas has,however,been poor,possibly because of a lack of understanding of the effects of psychosocial factors.Using data from previous research,this study aimed to better define the role of physical activity and FV intake in short;and long-term weight loss via changes in malleable psychosocial mediators and moderators.Methods:Women who were obese(n=183;age=50.0±7.9 years;body mass index=35.2±3.2 kg/m2,mean±SD)and who previously participated in 3 different community-based behavioral weight-loss treatments were assessed over 2 years.Changes in FV intake,physical activity,sei^regulation of physical activity and eating(aggregated),negative mood,and weight were measured over 6 and 24 months.Results'.Changes in each variable over both 6 and 24 months were significant(all p values<0.001).The FV intake to the weight-related caloric intake relationship(β=.0.30,p<0.001)was significantly mediated by selfregulation change over 6 months.The physical activity to weightchange relationship(β=.0.46,p<0.001)was significantly mediated by both sei±regulation and mood change over 24 months.Physical activity,itself,accounted for only 16%of weight-related caloric expenditure differences.Changes in physical activity and FV intake were each independent predictors of weight change over 24 months(overall R2=0.50,p<0.001).Conclusion-.Findings clarified theory-based targets for weight-management treatments and suggested that future weight-loss treatments strongly focus on developing self-regulatory skills to address barriers to behavioral changes.

Scottish Primary School Children Who Consume Greater Levels of Fruit and Vegetables Have Improved Health Markers

Background: There is conflicting information about whether Scottish children follow the UK government recommendation of consuming 5 portions of fruit and vegetable (F & V) a day, or whether increased intake of F & V promotes improved health. Objective: This study aimed to 1) perform a cross-sectional study of the number of F & V portions that primary school children consume in relation to age (4 - 13 years old) and sex, 2) establish the relationship between F & V intake and health parameters. Methods: Data were collected from 466 children using a specific F & V intake questionnaire. Health parameters (weight, height, blood pressure, waist circumference, hip circumference and lung function) were measured from all of the children. Results: Children consumed on average a total of 4.50 (SD 1.86) portions of F & V per day. F & V intake was not significantly different between girls and boys (t(464) = -0.397, P = 0.69). Children had greater intake of F&V on week day compared to weekend day (t(465) = 6.42, P ≤ 0.001). 42.2% children achieved the recommended F & V intake of five or more portions per day. After adjusting for age, sex and school, children who consumed more F & V had several markers of positive health including greater height, and parameters reflecting pulmonary function (FEV1 and FVC) were improved, while body weight, body fat, systolic blood pressure, pulse, waist circumference, hip circumference, waist to hip and waist to height ratio were all reduced. Conclusion: The recommended level of F & V or more can promote health among primary age children.
