Vegetables are pivotal food source to the human beings, representing the source of key nutrients, which in turn the occurrence of chronic diseases. Nonetheless, the consumption of poorly washed or in nature vegetables may expose individuals to the risk of infection by parasites. The aim of this study was to assess the contamination by parasites of medical and veterinary concern in raw vegetables used for human consumption. Fresh vegetables [i.e., lettuces (n = 50), carrots (n = 50) and beet (n = 50)] were acquired in different market places across the municipality of Garanhuns (northeastern Brazil) and the presence of parasites assessed by a sedimentation technique. Parasites were detected in 44.7% (67/150) of the evaluated samples. This study provides important data on the occurrence of zoonotic agents in vegetables. Therefore, strict hygienic measures should be adopted to reduce the risk for vegetable contamination leading to a reduction of human infection by pathogens of medical importance.

Summary An assessment is made of the hazards to man from parasites of laboratory animals. The chief danger arises from gastrointestinal helminths and protozoa of primates and tapeworms of rodents and prevention of infection depends on the adoption of normal hygienic measures for disposal of the faeces and bedding of experimental animals. Simian malaria constitutes a possible danger in those parts of the world where suitable vectors exist and in these areas the screening of animal houses against mosquitoes is necessary. Many ectoparasites of laboratory animals are capable of establishing themselves on human beings but their tenure is usually short. Infestation of man can be prevented only by control of the ectoparasites in the laboratory animals and this is desirable for the welfare of the animals themselves. The possibility of human infection with the parasites of laboratory animals can be greatly reduced by a period of quarantine immediately following arrival, during which examination is made for the presence of parasites and appropriate treatment given to remove any found to be present.

Nopalea Cochenillifera

Contaminated water consumption is one of the greatest risks to human health, especially in underdeveloped and developing countries. Water is a universal right, but millions of people worldwide consume untreated surface water. The objective in this study is to evaluate water purification with Nopalea cochenillifera var. Miúda biomass. Fragments (1, 2, and 3 g) of N. cochenillifera were added to the aqueous solution containing red-yellow Chromic and Podzolic Luvisol simulating turbid water sources in Northeastern Brazil. The total, non-structural (i.e., reducing and non-reducing sugars, alcohol insoluble solids), and structural (i.e., pectin) carbohydrates, adsorption kinetics, turbidity, electrical conductivity, pH, zeta potential, and total coliforms presence were evaluated. Findings show that the Nopalea cochenillifera biomass adsorbed the suspended particles in the aqueous solution, making it more translucent due to the complex and heterogeneous adsorbents’ ion exchange matrix, but the biomass addition did not eliminate total coliforms from the aqueous solution. We concluded that the Nopalea cochenillifera biomass water treatment reduces suspended dissolved particles and turbidity, but it needs to be associated with other treatments to eliminate total coliforms and ensure water safety for human consumption.

Covid-19 is not just a virus which is risking human lives everyday, but it is a phenomenon which has inflicted major changes on the long-term global survival and economic strategies. The pandemic has brought about major diversions in the world order, which philosophers and scientists have predicted to occur once in a century’s time. Covid-19 has also affected the personal health, physical and psychological of all human beings. It has forced people to change their social behaviors significantly, which has had consequential effect on their mental health. One significant result of the pandemic is the increased consumption of alcohol and other psychoactive substances among people. As people are forced to lock themselves up inside their homes, some have resorted to exercising, biking, running, and meditation to maintain sanity, while others have boosted their addictive behavior by consuming more alcohol and drugs to make staying-indoors more entertaining. Nielsen has reported a 54% rise in the national consumption of alcohol on the week of March 21st 2020, as compared to the same in 2019. The online sales of alcohol have also risen enormously from 2019 to 2020. The study aims to address the problem of increased alcoholism and substance abuse during Covid-19 by understanding the causes of this rise. The method is based on analysis and comparison of available survey reports, to find out exactly what amount of human consumption has increased during the pandemic. From the findings we can conclude that alcoholism and substance abuse has risen significantly during Covid-19, and psychological distress, anxiety and depression can be some major causes for this abnormal social behavior. It can also be implied that this increased alcoholism is likely to affect the physical health, neural and social behavior, and the work life of many human beings through the pandemic.

Fresh vegetables are an important part of a healthy diet. The consumption of raw vegetables without cooking or good washing can be a major rout of transmission to the parasitic infection. The goal of this study was to determine the intestinal parasitic contamination of fresh vegetables from vegetables sales markets in Baghdad province during the different above months of the year. A total of 303 samples of different vegetables were randomly selected from three wholesale markets distributed through different regions in Baghdad (East, West and South) and then were examined by a floatation method. The present study showed that the collected vegetables were contaminated with 12 species of intestinal parasites, and the total percentage of contamination was 161 (53.1%) . ZnSo4 solution showed the highest percentage of contaminated vegetables (31.2%) while sucrose showed the lowest percentage (8.9%).

Natural insecticides now-a-days have a bright future because synthetic insectides are harmful to human beings. Among botanical pesticides, the rotenoids standout for their potency and effectiveness against many crop pests and are fifteen times more toxic than the nicotinic acid. Cajanus cajan primarily grown as a grain crop for human consumption (pulse, vegetable) and has not been analysed for it’s rotenoidal content. Chromatographic analysis showed the presence of four rotenoids namely elliptone, deguelin, rotenone and tephrosin, which were identified by co-tlc, melting point, GLC and IR spectral studies with that of the standard reference compounds. In the present investigation, rotenone (0.37 mg/gdw) was found in maximum quantity which was followed by deguelin (0.27 mg/gdw), tephrosin (0.21 mg/gdw) and elliptone (0.15 mg/gdw).

AIM: There is currently no consensus regarding the physical and chemical variability of tropical reservoirs. In semiarid Northeastern Brazil, reservoirs are among other things used for human consumption, industrial water supply and intensive fish farming, all of which can impact water quality. The objective of this study was to evaluate the physical and chemical variability of the water in Sítios Novos, a reservoir in semiarid Northeastern Brazil, comparing samples collected in areas of intensive tilapia (Oreochromis niloticus) farming to samples from areas not directly impacted by aquaculture, in both the dry and the rainy season. METHODS: Between October 2010 and July 2011, data were collected on temperature, conductivity, pH, turbidity, salinity, chlorophyll a, dissolved oxygen, oxygen demand, total phosphorus and total nitrogen levels in the water column using a multiparametric probe at four different sampling locations. Physical and chemical differences between the four locations were evaluated with the Kruskal-Wallis (KW) test and Dunn's post test, while the t test, followed by Welchʼs correction, was used to compare samples collected in different seasons. RESULTS: No influence of intensive aquaculture was detected when comparing sampling locations near fish farms (180C and 300C) to locations not directly impacted by aquaculture (LIMN1, near the dam, and LIMN2, near the debouch of the São Gonçalo river). However, the sampling locations differed significantly (p<0.05) with regard to conductivity, pH, turbidity and chlorophyll a levels. CONCLUSIONS: The physical and chemical variability was greater between seasons than between locations when the data were analyzed with the t test. That analysis showed significant differences for 22 of 40 comparisons between the 10 physical and chemical parameters in the two seasons at the four sampling locations. In conclusion, the physical and chemical variability registered for the Sítios Novos reservoir throughout the study period indicates morphometric, meteorological and hydrological heterogeneity, with emphasis on the differences between LIMN2 and the other three sampling locations and between the rainy season and the dry season. According to the calculated trophic status index, the reservoir is supereutrophic in the rainy season and supereutrophic to hypereutrophic in the dry season.

And Coping

Poultry farmers face a dual risk when mutant avian influenza (AI) virus exhibits zoonotic characteristics. A/H5N1 and A/H7N9 are two principal strains of the AI virus that have captured public attention in recent years, as they have both been reported and can infect poultry and humans, respectively. Previous studies have focused either on poultry farmers’ risk perception and biosecurity preventive behaviors (BPBs) against A/H5N1 infection with poultry, or on their risk perception and personal protective behaviors (PPBs) against human infection with A/H7N9, even though these two strains often appear simultaneously. To bridge this research gap, a survey (N = 426) was conducted in the Chinese provinces of Jiangsu and Anhui to assess risk perception and coping behaviors adopted by poultry farmers facing the dual risk of these two viral strains. Paired sample t-tests revealed that farmers’ perceived risk of poultry infection with A/H5N1 was significantly higher than their perceived risk of human infection with A/H7N9, and that their reported frequency of BPBs against A/H5N1 was significantly higher than the frequency of PPBs against A/H7N9. Moreover, farmers were less familiar with AI infection in human beings compared to that in poultry, but they felt a higher sense of control regarding human AI infection. Multivariate regression analyses showed that farm size and perceived risks of both human and poultry infection with AI were positively associated with BPBs and PPBs. The findings of this research suggest that a campaign to spread knowledge about human AI infection among poultry farmers is needed, and that a policy incentive to encourage large-scale poultry farming could be effective in improving implementation of BPBs and PPBs.

Recovery Methods

ABSTRACT: Liquid pig manure (LPM) is widely used as a compost fertilizer for vegetable crops destined for human consumption. However, these wastes may contain parasites eggs, such as the nematode Ascaris suum, that pose serious health risks to humans. We attempted to determine the most appropriate technique for recovering A. suum eggs from LPM compost. Samples were collected from two waste sources during composting, including 23 samples containing LPM, sawdust, and wood shavings, and 14 samples of LPM alone-both in triplicate. Samples were analyzed using several different recovery methods. Recovery of eggs by the modified Bailenger method with adaptations was significantly more effective and recovered 57% more eggs than by the modified Bailenger method alone. Willis-Mollay method, modified Faust method, and the simple sedimentation technique only recovered 4.4%, 13.9%, and 26% of eggs, respectively, compared with the modified Bailenger method with adaptations, indicating that the adjustments made to the Bailenger method were key to improving the recovery of A. suum eggs from compost and LPM.
