Street vended juices are most commonly available, accessible and economical nutritional food sources of poor slums in developing economies like Pakistan. Study was undertaken to elucidate impact of industrialization, agro chemicals induction in agronomic practices and food processing hygiene measurements on food chain heavy metals intoxication. If overlooked, certain quality risks associated either with fresh produce or processed commodity might initiate food intoxication.In order to understand gravity of the issue, street vended freshly drawn juices extracted from the food crops (orange, sugarcane, carrot and mango) cultivated in <em>Southern Punjab </em>peri-urban areas and country sides were evaluated for microelements and heavy metals load in summer and winter 2012. The safety study of juices depicted higher concentration of lead (Pb) and cadmium (Cd) breaching international safety limits implemented in the country. However some microelements (Fe, Zn, Mn) were found below the prescribed maximum tolerant limits. The study concluded prevalence of higher concentration of some toxic heavy metals as a serious breach of threshold levels potentially compromising consumer’s safety.

Soy Meal

Most soybean oil consumed in China is made from imported genetically modified (GM) soybeans, while livestock are fed imported GM soy meal and GM corn. However, no GM food crops are allowed to be planted in China at present. That puts China in a confusing situation where GM foods can be eaten but cannot be grown. Many studies suggest that it is partially due to Chinese consumers’ and government officials’ opposition to GM technology. This is the first study that examines different stakeholders’ and journalists’ attitudes toward the commercialization of GM non-food crops and GM food crops and investigates the attitude gaps with respect to these crops. From 2015 to 2016, surveys were conducted face-to-face and by email with 1730 respondents, including 1460 consumers, 54 farmers, 70 journalists, and 146 agricultural officials. We find that nearly 60% of respondents are supportive of the commercialization of GM non-food crops, but less than 30% of respondents support the commercialization of GM food crops. Around 50% of respondents have no confidence in the government’s management of biotechnology, while only 17% have confidence in the government’s management. Those with lack of confidence in the government’s management are less likely to support the commercialization of GM crops.

The use of genetic modification (GM) technologies to modify food crops provides one of the most hotly debated and often discussed applications of science. As the science develops, new generations of GM crops will be produced and current consumer views might change. This brief paper discusses mechanisms by which the complexity of decision-making at the regulatory level might be better understood by the public and hence provide tools for individuals to inform their own views and purchasing choices.

Risks And Benefits

Genetically modified (GM) crops and biotechnology are providing new opportunities for increasing crop productivity and tackling agriculture problems, such as diseases, pests and weeds, abiotic stress and nutritional limitations of staple food crops. As GM crops are being adopted in various locations with different ecosystems, a scientifically based understanding of the environmental effects of cultivations of GM crops would assist decision makers worldwide in ensuring environmental safety and sustainability. In this paper are discussed some of the most important problems related to the GM crops into the environment such as: plant protection, hybridisation, ecological effects of HRCs, gene flow, biodiversity, stress, ecological risks (ERA), effects on the soil ecosystem etc.

Consumer Benefit

PurposeMany countries have held back from planting genetically modified (GM) food crops due to perceived negative reaction in export and domestic markets. Three lines of research have tested the reality of this fear.Design/methodology/approachIn‐depth interviews were conducted in European countries with key companies and organisations in the European food sector. Supermarket intercepts were used to ascertain purchasing intent for products from countries that do or do not produce GM crops. A purchasing experiment was conducted, where cherries labelled as GM, organic or conventional were on sale in a roadside stall.FindingsFood distribution channel members expressed concern about possibility of contamination or mix‐up between GM and non‐GM food. However, presence of GM crops in a country does not cause negative perception of food in general from that country. Approximately 30 per cent of consumers in the purchasing experiment proved willing to purchase GM cherries when there was a defined consumer benefit – either lower price or spray‐free.Practical implicationsCountries that have not yet planted GM food crops need to be cautious about possible negative impacts on channel member perceptions of non‐GM versions of the same crop from the same country. However, planting GM crops does not appear likely to damage the overall reputation of a food‐supplying country. GM applications in non‐food areas seem unlikely to damage perceptions of country image in relation to supply of food products from that country.Originality/valueProvides useful information for those planning to plant GM food crops.

AbstractSafety assessment of genetically modified (GM) crops is crucial in the phase of product development before the GM crops are put on the market. Characteristics of flanking sequences of exogenous insertion sequences are essential for the safety assessment and marking of transgenic crops. In this study, we used the methods of genome walking and whole genome sequencing (WGS) to identify the flanking sequence characteristics of a SbSNAC1 transgenic drought-tolerant maize line “SbSNAC1-382”, but both of the methods failed. Then, we constructed a genomic fosmid library of the transgenic maize line, which contained 4.18×105 clones with an average insertion fragment of 35 kb, covering 5.85 times of the maize genome. Subsequently, three positive clones were screened by pairs of specific primers and one of the three positive clones was sequenced by using the Single Molecule Real-Time (SMRT) sequencing technology. More than 1.95 Gb sequence data (∼105 × coverage) for the sequenced clone was generated. The junction reads mapped to the boundaries of T-DNA and the flanking sequences in the transgenic line were identified by comparing all sequencing reads with the maize reference genome and the sequence of transgenic vector. Furthermore, the putative insertion loci and flanking sequences were confirmed by PCR amplification and Sanger sequencing. The results indicated that two copies of the exogenous T-DNA fragments were inserted in the same genomic site. And the exogenous T-DNA fragments were integrated at the position of Chromosome 5: 177155650 to 177155696 in the transgenic line 382. Herein, we have demonstrated the successful application of the SMRT technology for the characterization of genomic insertion and flanking sequences.
