Pesticides are majorly used in agricultural fields for crop protection but even after having agricultural benefits it also has negative acute toxic effects on human beings and environment. Accumulation of these toxic substances in the living life cycle prove to be a source of diseases and causes of deaths if accumulated in higher concentration. This research involves a method to detect the quantity of pesticides accumulate in our edibles which we consume, so as to ensure the quality of food we eat. For this purpose, a colorimetry method can be used which is the application of beer-Lambert law (1) that measures the concentration of solute by measuring the loss of intensity of light which is passing through the solution.

Food Safety And Quality

The food market grew circumstantially in recent years and the quality of services and products is the distinguishing factor among many companies in the field of food. The Foodborne Diseases (FD) are serious public health problem, and it is in this context that it becomes important to ensure food hygiene as a priority component of food safety. The objective was to evaluate the physical and structural hygiene fridge, cold, bakery and FFV (Fresh Fruits and Vegetables) in a supermarket chain sectors Teresina-PI conditions. Selected at random ten supermarkets located in four zones of the city that were evaluated through a check-list containing questions relating to health and hygiene handler, facilities and equipment. It was found that, as to the adequacy, no area was classified as poor, with the best grades were supermarkets B, F and C, belonging to different parts of the city. The adjustments ranged from fair to good, showing a concern for the quality control in some supermarkets while, in others, leaving a little aside this issue, which is worrying, since the quality of food is the key point health of human beings.

AbstractObjectivesTo assess the nutritional quality of food aid delivered by food banks in France and to identify practical modifications to improve it.DesignNational-level data were collected for all food aid distributed by French food banks in 2004, and its nutrient content per 2000 kcal was estimated and compared with French recommendations for adults. Starting with the actual donation and allowing new foods into the food aid donation, linear programming was used to identify the minimum changes required in the actual donation to achieve the French recommendations.ResultsFrench food-bank-delivered food aid does not achieve the French recommendations for dietary fibre, ascorbic acid, vitamin D, folate, magnesium, docosahexaenoic acid, α-linolenic acid and the percentage of energy from saturated fatty acids. Linear programming analysis showed that these recommendations are achievable if more fruits, vegetables, legumes and fish were collected and less cheese, refined cereals and foods rich in fat, sugar and/or salt. In addition, new foods not previously collected are needed, particularly nuts, wholemeal bread and rapeseed oil. These changes increased the total edible weight (42%) and economic value (55%) of the food aid donation, with one-third of its edible weight coming from fruits and vegetables, one-third from staples, one-quarter from dairy products and approximately a tenth from meat/fish/eggs.ConclusionsImportant changes in the types and amounts of food collected will improve the nutritional quality of food-bank-delivered food aid in France. Such changes are recommended to improve the diets of deprived French populations.

Fenvalerate (Fen) is a synthetic pyrethroid, which is commonly used for destroying a variety of insect pests damaging several vegetable, fruit, and cotton crops. This insecticide is also used to mitigate household insects like flies, cockroaches, mosquitoes, and so forth. Human beings are exposed to formulated Fen preparations mostly by inhalation during spraying in fields for crop protection, for control of household insects, and also during handling and packaging at manufacturing plants. Limited online information is available regarding toxic effects of formulated Fen exposure on mammalian reproductive system. The present study has been undertaken to investigate male reproductive toxic effects of a formulated preparation of Fen (20% EC) particularly in relation to steroidogenic alterations in testes and sera of rats exposed by nose-only inhalation for (4 hours/day and five days a week) for three months. The results indicate significant reduction in the weight of testes, epididymal sperm counts, and sperm motility, along with decrease in marker testicular enzymes for testosterone biosynthesis viz. 17-b-hydroxy steroid dehydrogenase (17-b-HSD) and glucose-6-phosphate dehydrogenase (G6PDH), leading to net decrease in serum testosterone concentration in group of rats exposed to onefifth LC50 of Fen (20% EC) by inhalation (4 hours/day, five days a week) subchronically for three months. These results for the first time indicate the role of testosterone in Fen (20% EC)-induced male reproductive toxicity of rats subchronically exposed by inhalation probably due to neuroendocrine-mediated phenomenon and hormone-disrupting property of the insecticide.

AbstractObjectiveTo evaluate the quality of food choices according to adolescent individual earnings in Brazil.DesignAdolescents were classified according to their individual earnings as having or not having spending power for their own expenses. Food records from two non-consecutive days of the Brazilian National Dietary Survey (NDS 2008–2009) were used to estimate food intake. Quality of food choices was based on two approaches: (i) the NOVA classification, which classifies processed and ultra-processed foods and drinks as unhealthy food groups; and (ii) traditional classification, with beans, milk, fruits and vegetables as healthy food groups, and soft drinks, sweets, snacks and crackers classified as unhealthy. We compared mean food intake (g/kJ or ml/kJ) according to per capita household income (tertiles) and adolescent individual earnings, with adolescent earnings adjusted for household income, using multiple linear regression.SettingBrazilian households (n 13 569).SubjectsAdolescents aged 14–18 years (n 3673).ResultsMales without individual earnings had higher per capita household income than those with individual earnings. Household income was associated with all three food groups of the NOVA classification and seven of the eight groups of the traditional classification. However, only beans and snacks were consumed in significantly greater quantities by adolescents with individual earnings compared with those without earnings.ConclusionsAdolescent individual earnings were not the main driver of food choices; however, per capita household income was associated with food choices. The consumption of both healthy and unhealthy items increased with increasing household income.

Poisonous Mushrooms

Mushroom poisoning has always been a threat to human health. There are a large number of reports about ingestion of poisonous mushrooms every year around the world. It attracts the attention of researchers, especially in the aspects of toxin composition, toxic mechanism and toxin application in poisonous mushroom. Inocybe is a large genus of mushrooms and contains toxic substances including muscarine, psilocybin, psilocin, aeruginascin, lectins and baeocystin. In order to prevent and remedy mushroom poisoning, it is significant to clarify the toxic effects and mechanisms of these bioactive substances. In this review article, we summarize the chemistry, most known toxic effects and mechanisms of major toxic substances in Inocybe mushrooms, especially muscarine, psilocybin and psilocin. Their available toxicity data (different species, different administration routes) published formerly are also summarized. In addition, the treatment and medical application of these toxic substances in Inocybe mushrooms are also discussed. We hope that this review will help understanding of the chemistry and toxicology of Inocybe mushrooms as well as the potential clinical application of its bioactive substances to benefit human beings.

Prisoners form the most ignored community, and their rights are most overtly denied and treated as degraded human beings. Prisons are looked down as burden on state exchequer. Allocation for welfare activities of prisoners formed only 0.6 % of total prison budget. Prisons are highly congested with minute care toward maintenance, hygiene, sanitation, and quality of food along with severe staff crunch. Currently, prisons are the hub to the suppression of human dignity and natural rights. Mostly overlooked, extremely stigmatised and least cared and discussed for, and mostly coming from the already marginalised sections, prisoners get trapped in the vicious circle of living a hell life. It’s the crime which needs to be shaded off not the criminal per se. Only with such improvements availability of procreation right would bring respite especially toward the women and children involved. Things need to be moved hand in hand. In this article author tries to throw light own issues that must be looked into while drafting policies for prisoners’ rights.

Pesticides are applied in agricultural fields for controlling pest population to achieve crop protection. But they cause damage to nontarget organisms and affect the quality of environment including water, air and soil. The present study has been designed to test the efficiency of Pseudomonas stutzerion the degradation of malathion. The bacterial strain was subjected to 50, 100, 150 and 200 ppm of malathion in minimal broth for 30 hours and changes in orthophosphate levels, pH and turbidity were monitored for every six hours. Efficiency of free and immobilized cells were compared for orthophosphate release. Influence of different sugars on degradation was also compared. Degradation of 150 ppm of malathion was confirmed with UV-Visible spectrophotometric analysis and HPLC analysis. The data were subjected to two way analysis of variance and the results are discussed.

Food Product Development

The quality of food products is determined by physical properties, chemical composition, the level of contaminants (microbiological and toxic substances) and sensory attributes. Consumers around the world demand consistent supply of quality food products that reflect the value of the price they pay for them. The nature of raw materials and ingredients reflect the quality of food products in the market. Raw materials as well as packaging materials should be purchased based on the quality specifications that suppliers should adhere to. This review aimed at highlighting the importance of using objective assessment tools and consumer/sensory evaluation in determining the quality and acceptability of new food products. Objective tests are used to measure one particular attribute of a food product rather than its overall quality. They are generally rapid, reliable and repeatable. On the other hand sensory methods measure the reaction to stimuli resulting from the consumption of a product. Sensory testing is often used to determine consumer acceptability of a food product and contributes to the design of quality systems hence considered as a technical support for quality assurance during food production. Not only that but also it helps to obtain feedback for making decisions and carrying out proper modification of a particular food product. Therefore objective methods and sensory evaluation are indispensable tools for routine quality control of new food products as well as the existing ones.

This study examined the effect of raw materials on the quality of catering services in daycare centers in Nyeri Town Constituency, Kenya. The development and growth of a child depend to a great extent on what they consume as food. For a good development of a child, there is a need to consider the quality of food he or she takes. This is in relation to nutritional value, quantities per intake, quality in relation to cleanness, methods of cooking and its presentation to the child.  This high level of participation in childcare centers is attributed to an increasing awareness that early childhood centers are considered critical support in the development of young human beings to become useful citizens. The study targeted all 16-day care centers in Nyeri Town Constituency which are licensed to operate. A total of 64 respondents were targeted which included the managers of the daycare centers and three staff members working in catering sections as follows: stores, production, and service formed the respondents. This study employed a purposive sampling technique in selecting the constituency in the county where the research was carried out. The R-value is 0.689 which indicates a strong correlation. The R2 value indicates how much of the dependent variable (quality of catering services), can be explained by the independent variable (effects of raw materials’). This study concludes that the management of the catering departments in daycare centers should ensure different types of food are stored in different rooms.

Green revolution is one of the basic need to save our planet and our country from burning environmental issues, there were quantum bounce in the use of synthetic pesticides which play an important role in agriculture to control destructive pests such as insects, weeds, plant disease causing pathogenic organisms, nematodes, arthropods and vertebrates, that cause danger to quality of food products such as fruits and vegetables, hazardous to the environment, affects soil fertility and causing imbalance in nature. Currently there have been some Physico -chemical and biological methods which are used to reduce pesticides. However, these methods are not efficient, cost effective and time consuming. Whereas, bioremediation is novel tool or ecofriendly approach used for cleaning up contaminated environments using different microbial species such as bacteria, fungi, Actinomycetes and some green plants. Bioremediation is less invasive method, ecofriendly, economical, more efficient and restorative of soil function. Most of the pesticides generally fall into the major classes of organochlorines, chlorophynoxy acids, carbamates, organophosphorous. My present study focused on understanding bioremediation mechanisms, involvements of different microbes and its vital role in removing pesticides of different categories
