Animal feeds are routinely subject to contamination from diverse sources, including environmental pollution, activities of microbes, and veterinary drug residues. Contamination of feed with chemical substances such as coccidiostats or antibiotics can occur at the stage of production, transport and storage, and their presence may have a negative impact on the health of animals consuming feed contaminated with certain chemicals. This study presents the legal requirements for the production of feed, the presence of antimicrobial substances in feed, and the problem of contamination of feed with antibacterial substances as well as the possible transfer of these compounds to the animal tissues and the natural environment.

Silage has a substantial role in ruminant nutrition. Silages as a source of mycotoxigenic fungi and mycotoxins merit attention. Fungal growth and mycotoxin production before and during storage are a well-known phenomenon, resulting in reduced nutritional value and a possible risk factor for animal health. Mycotoxin co-contamination seems to be unavoidable under current agricultural and silage-making practices. Multi-mycotoxin contamination in silages is of particular concern due to the potential additive or synergistic effects on animals. In regard to managing the challenge of mycotoxins in silages, there are many factors with pre- and post-harvest origins to take into account. Pre-harvest events are predominantly dictated by environmental factors, whereas post-harvest events can be largely controlled by the farmer. An effective mycotoxin management and control programme should be integrated and personalised to each farm at an integrative level throughout the silage production chain. Growing crops in the field, silage making practices, and the feed out phase must be considered. Economical and straightforward silage testing is critical to reach a quick and sufficiently accurate diagnosis of silage quality, which allows for ‘in field decision-making’ with regard to the rapid diagnosis of the quality of given forage for its safe use as animal feed. Regular sampling and testing of silage allow picking up any variations in mycotoxin contamination. The use of rapid methods in the field represents future challenges. Moreover, a proper nutritional intervention needs to be considered to manage mycotoxin-contaminated silages. At farm level, animals are more often exposed to moderate amounts of several mycotoxins rather than to high levels of a single mycotoxin, resulting more frequently in non-specific digestive and health status impairment. Effective dietary strategies to promote rumen health, coupled with the administration of effective and broad-spectrum mycotoxin detoxifiers, are essential to minimise the negative impact of mycotoxins.

In agriculture and the production of grain feeds, in spite of all the measures of protection and control, the presence of molds in grains is almost unavoidable. Molds contaminate the animal feed and/or nutrients during the growth of plants, as well as in all the handling operations - during harvest, mowing, picking, transport and storage. The comparative research on presence and identification of molds, shown in this paper, was carried out in two phases, in 2011 and 2014, on the samples of grains, stored and intended for animal nutrition. In total, 72 samples of different grains were examined, most of them related to maize (56) from a domestic production in the Banja Luka region. Mycological analysis i.e. quantification and determination of fungi in all samples revealed dominant presence of Fusarium species in both phases. The occurrence of Fusarium species in 2011 and 2014, expressed as relative values, were 61.11% and 80.55%, respectively.

Teachers and advisors involved in the emotional business of language education feel frustrated from time to time, and if such emotions are not managed healthily, they may lead to negative outcomes such as stress and burnout. One important system for taking control of frustration is emotion regulation, the cognitive and behavioural strategies through which individuals manage their emotions. In this short article, I define frustration and discuss its negative impact on the language classroom. I then introduce a structured reflective journaling tool, built upon Gross’s Process model of emotion regulation (Gross, 2014, 2015) which may help teachers and advisors develop greater awareness and control over experiences of frustration.

Historically, chemicals exceeding maximum allowable exposure levels have been disastrous to underdeveloped countries. The global food industry is primarily affected by toxic chemical substances because of natural and anthropogenic factors. Food safety is therefore threatened due to contamination by chemicals throughout the various stages of food production. Persistent Organic Pollutants (POPs) in the form of pesticides and other chemical substances such as Polychlorinated Biphenyls (PCBs) have a widely documented negative impact due to their long-lasting effect on the environment. This present review focuses on the chemical contamination pathways along the various stages of food production until the food reaches the consumer. The contamination of food can stem from various sources such as the agricultural sector and pollution from industrialized regions through the air, water, and soil. Therefore, it is imperative to control the application of chemicals during food packaging, the application of pesticides, and antibiotics in the food industry to prevent undesired residues on foodstuffs. Ultimately, the protection of consumers from food-related chemical toxicity depends on stringent efforts from regulatory authorities both in developed and underdeveloped nations.

AbstractA pre-economic feasibility study was undertaken to determine the potential of cereal straw for industrial utilization in Minnesota. Specifically, utilizing straw for pulp and paper manufacture was of interest. The availability of cereal straw fiber supplies at various locations across the state of Minnesota, along with pre-processing issues such as transportation, harvesting, handling, and storage, are discussed and priced. The greatest economic advantage of straw for industrial use appears to be the low cost of the raw material compared to traditional raw materials. This also provides an excellent opportunity for additional income for farmers. The methodology and information provided here should be helpful in evaluating the feasibility of utilizing straw for other industrial purposes in other parts of the world. However, in some Third World countries, long-standing on-farm, traditional uses of cereal straws for fuel, fiber, and animal feed may limit their availability for industrial utilization.

The protracted outbreak of mad-cow disease, repeated episodes of dioxin and mycotoxin contamination, and the issue of labelling genetically modified foods have severely shaken public confidence in the food supply industry, increasing consumer concerns about the origins of the raw materials used in both animal feed and food products. The need to develop improved techniques to characterize feed and food components has consequently become more urgent, and DNA-based technologies promise to be able to meet these needs. DNA methods can establish the origin of species in meat- and fish-based products and feed ingredients, and are the most reliable analytical approaches for authenticating processed foodstuffs. The identification of ingredients in processed feed and food is mandatory not only to ensure correct labelling and assessment of value, but also to avoid health risks related to the presence of toxic contaminants or pathogenic agents.

Objective: The purpose of our research is to emphasize the role of underestimated predisposing conditions for microbial keratitis in contact lens users, to draw attention to the complications of wearing contact lenses without ophthalmic examination, and to offer a short questionnaire for fast and easy estimation of the risk factors for bacterial keratitis. Methods: A series of 23 cases of healthy young individuals, treated for bacterial keratitis, provoked а research on the predisposing factors for its development. Results: 55% of the patients had started to wear contact lenses without specific examination. 75% had made mistakes in the hygiene and storage of the lenses. We identified risk factors for development of bacterial keratitis in all cases. Conclusions: A thorough anamnesis and ophthalmic examination are crucial in decision making about contact lens wearing because they could reveal some of the predisposing conditions for the occurrence of ocular complications. The usage of contact lenses without a prescription poses health risks and could have a negative impact on the social and healthcare system.

The objective of this empirical study is to explore the effect of the adoption of ERM on the performance of the diversified industry of Sri Lanka. The extent of the adoption of ERM is assessed based on eight ERM functions recognized by the ERM integrated framework of the committee of sponsoring organization of the Treadway Commission and use return on equity as a proxy to measure firm performance. This study finds ERM supportive internal environment, risk-aligned objective setting, event identifications, and risk response have a positive impact on firm performance. However, none of those impacts were statistically significant. Surprisingly, empirical evidence reveals that risk assessment and control activities have a negative impact on the firm performance. Information & communication and monitoring functions indicate a significant impact on firm performance. Nevertheless, monitoring function shows a negative impact on the firm performance. The researcher believes this negative impact is attributable to the increased cost of monitoring activities that is crucial for a diversified business setup. This empirical evidence induces the researcher to conclude that, except for communication and monitoring, the adoption of ERM has no significant impact on the firm performance. These findings are contradictory with the findings of prior researchers.
