Food Of Animal Origin

AbstractThe organic food sector and consumer interest in organic products are growing continuously. The safety and quality of such products must be at least equal to those of conventional equivalents, but attaining the same standards requires overcoming a particular problem identified in organic food production systems: the occurrence of bacterial pathogens such as Salmonella, Campylobacter, Listeria monocytogenes, Staphylococcus aureus and pathogenic Escherichia coli. These food-borne microorganisms were detected in the production environments of such food. The prevalence of pathogenic bacteria in organic livestock and products may be higher, but may also be the same as or lower than in like material from conventional farms. Furthermore, the incidence of antimicrobial-resistant bacteria was more often detected in conventional than in organic production. The aim of this review was to present the recent information on the microbiological safety of food of animal origin produced from raw materials from organic farms.

The article provides general information on organic production, in order to obtain quality and safe poultry products that meet the requirements of current national, European and international legislation. Factors that may cause a risk in the roduction of organic food of animal origin are considered, taking into account the stages of primary production and specific requirements for keeping organic poultry, given the requirements for animal welfare. There have been identified biological, chemical and physical hazards that can reduce the profitability of production and affect the quality of poultry products, taking into account the peculiarities of organic livestock management and ensuring the welfare of animals in organic production. The given list of natural prophylactic drugs that can be used in organic livestock as an alternative to antimicrobial drugs, and demonstrated an example of prophylactic use in organic farming of young poultry, which resulted in increased poultry safety. It were compared certain parameters of the microclimate under conditions of intensive poultry farming vs poultry kept under the requirements of organic production. Microbiological air contaminations in poultry houses at industrial poultry farming system were exceeding the standard limits, when in organic poultry farming condition a significant reduction of the number of bacteria in the air was indicated. The list of national, European and international regulations governing the requirements for keeping poultry during organic production is given. It has been established the necessity of comprehensive approach for supporting the health of animals, their feeding and management, systematic monitoring of compliance with health and hygiene requirements of animals and poultry farming, products processing, obtaining high-quality, safe products to avoid risks in the chain for the successful development of the organic production. Key words: organic production, poultry farming, hazards, risk analysis, microclimate, organic food, probiotics.

AbstractIntensive animal farming emits to the environment very high concentrations of bioaerosol, mainly composed of microorganisms, including antibiotics resistant strains, and their derivatives. Poland is a significant producer of poultry and swine in Europe; Ukraine is located in the immediate vicinity of Poland and the EU. Thus, the review focuses on the presence of potentially pathogenic and antimicrobial-resistant zoonotic bacteria and antimicrobial genes in the environment of farms and food of animal origin in Poland and Ukraine. Existing data confirms presence of these bacteria in the food animal origin chain environment in both countries. However, it is difficult to compare the scale of multidrug-resistant bacteria (e.g. MRSA, ESBL) dissemination in Poland and Ukraine with other EU countries due to lack of more extensive studies and large-scale monitoring in these two countries. A series of studies concerning resistance of pathogenic bacteria isolated from livestock environment have been published in Poland but usually on single farms with a very limited number of samples, and without a genotypic drug resistance marking. From Ukraine are available only few reports, but also disturbing. The risk of antibiotic-resistant bacteria transmission does not only concern animal farming, but also other facilities of animal origin food supply chains, especially slaughterhouses.

ABSTRACT Antibiotics have always appeared miraculous, saving innumerable lives. However, the unwise use of antimicrobial drugs has led to the appearance of resistant bacteria. The purpose of this study was to evaluate antimicrobial resistance in Escherichia coli (n =160) isolated from food of animal origin. The focus was on E. coli–producing extended-spectrum β-lactamases. E. coli was chosen because it is a part of the normal microbiota in mammals and can enter the food chain during slaughtering and food manipulation. Subsequently, its resistance genes can be transferred to pathogenic bacteria and human microbiota. Phenotypic and genotypic analyses of selected antimicrobial resistances were carried out together with a molecular analysis of virulence genes. E. coli isolates from food of animal origin were compared with clinical E. coli strains isolated from the human intestinal tract. Extended-spectrum β-lactamase–producing E. coli isolates were found in 9.4% of food isolates and in 1.8% of intestinal isolates. Phylogenetically, the majority of food (86.3%) and intestinal E. coli (58.1%) isolates were found to belong to the commensal phylogenetic groups A and B1. The distribution of 4 of 14 analyzed virulence factors was similar in the food and intestinal isolates. Strains isolated from food in Slovenia harbored resistance genes and virulence factors, which can constitute a problem for food safety if not handled properly.

Organic agriculture is a production system that relies on prevention, ecological processes, biodiversity, mechanical processes, and natural cycles to control pests and maintain productivity. Pesticide use is generally limited or absent in organic agroecosystems, in contrast with non-organic (conventional) production systems that primarily rely on pesticides for crop protection. Significant differences in pesticide use between the two production systems markedly alter the relative dietary exposure and risk levels and the environmental impacts of pesticides. Data are presented on pesticide use on organic and non-organic farms for all crops and selected horticultural crops. The relative dietary risks that are posed by organic and non-organic food, with a focus on fresh produce, are also presented and compared. The results support the notion that organic farms apply pesticides far less intensively than conventional farms, in part because, over time on well-managed organic farms, pest pressure falls when compared to the levels on nearby conventional farms growing the same crops. Biopesticides are the predominant pesticides used in organic production, which work by a non-toxic mode of action, and pose minimal risks to human health and the environment. Consequently, eating organic food, especially fruits and vegetables, can largely eliminate the risks posed by pesticide dietary exposure. We recommend ways to lower the pesticide risks by increased adoption of organic farming practices and highlight options along organic food supply chains to further reduce pesticide use, exposures, and adverse worker and environmental impacts.

Common Purslane

Weed management is often difficult and expensive in organic production systems. Clove oil is an essential oil that functions as a contact herbicide and may provide an additional weed management tool for use on organic farms. Burning nettle, purslane, and rye responses to 5, 10, 20, 40, and 80% v/v clove oil mixture applied in spray volumes of 281 and 468 L/ha were examined. Log-logistic curves were fitted to the nettle and purslane data to determine the herbicide dose required to reduce plant dry weight 50% (GR50) and 90% (GR90). A three-parameter Gaussian curve was fitted to the rye data. The GR50 and GR90 were largely unaffected by spray volume. Nettle dry weight was reduced by 90% with 12 to 61 L clove oil/ha, whereas 21 to 38 L clove oil/ha were required to reduce purslane biomass to the same level. Rye was not effectively controlled by clove oil. Clove oil controls broadleaf weeds at high concentrations, but its cost makes broadcast applications prohibitive, even in high-value vegetable production systems.

Organic Farming Systems

Given relatively low adoption levels to date, the potential benefits of organic farming systems are not yet very visible. However, there is growing evidence in the literature that adoption of such systems produces multiple environmental, social, and financial benefits that can solve pressing agricultural problems in Canada. Compared with their duration as conventional operations, most organic farms in North America perform better under organic management. This outcome is usually a product of lower input costs, more diversified production and marketing channels, resilience in the face of variable market conditions, higher premiums, and a better capacity to adapt to weather extremes. However, the performance of farming systems including some horticultural and animal production systems, for which our ecological understanding is limited, is still frequently inferior. The data on social impacts are less conclusive, but there is some evidence that when a community has many sustainable (including organic) producers , there are positive shifts in community economic development and social interaction. The reasons appear to be related to the need to hire more labour, the increased demand for local goods and services, and a greater commitment to participation in civic in stitutions. Key words: Organic agriculture, economic performance, social benefits

The new millennium, Y2k as it is internationally symbolized, has come closer, and as doomsayers use to say "Plan for the worst in order to hope for the best". Starting up from the scandal of the identification of high concentrations of dioxin residues in foods of animal origin, it is imperative to refer to this group of chemical pollutants which they have been, they are and they will be the focus of the interest for many years to come. Polychlorinated dibenzo-para-dioxins [PCDDs] and polychlorinated dibenzofuranes [PCDFs] are by-products of industrial processes for the production of organochlorine pesticides [OCPs], polychlorinated biphenyls [PCBs], wood conservation industries, chlorine bleaching of pulp and paper industries, but also the result of municipal solid waste management [MSW] with special attention to recycling processes whose environmental emission are extremely high. From the other hand, we should have to realize that dioxins have been a natural contaminant of our environment for more than 60 million years. Taking into consideration the Tolerable Daily Intake [TDI], which has been set to 1 pg-4pg I-TEQ/kg.b.w. [quantity which includes together dioxins, furans and polychlorinated biphenyls], based on their mode of action and toxicity, it is obvious that the measures which the competent authorities of every country have to put in place for the control of raw materials and food of animal origin, should have to be strict, systematic, permanent and reliable so that they safeguard consumer's health as better as they can.

Higher education curricula should be alert to trends in production and science, and responsive to needs of producers and consumers in our society. A recent trend has emerged nationally and internationally for the production and consumption of certified organic produce which is increasing at a significant rate. Following the creation of the National Organic Program and formal federal regulations for certification which govern production, it has been questioned whether horticulture programs in land grant institutions have adjusted curricula appropriately to train producers, consultants, extension specialists, teachers and research scientists to be engaged in organic production systems. According to USDA statistics, several states in the southern region have significantly fewer certified organic farms and certifying agencies than the northeast, Midwest or western regions. A review horticulture and crops programs at 36 land grant universities (1862 and 1890) in 14 southern region states indicated although several institutions had research and outreach programs for sustainable and organic production, there were only three classes on organic gardening, two classes on organic crops production, and one field-based organic production course that could be identified in existing curricula. It appears that with the growth of the organic industry worldwide that students in programs in the southern region may be under-served in this educational area. Further, it may be questioned whether the lack of production and certifying agencies in the southern region is associated with the lack of science-based education provided by the land grant universities. A recent survey of faculty indicated a perceived need for stand-alone coursework on organic, sustainable, and ecologically-based production systems.
