Composition differences between organic and conventional meat: a systematic literature review and meta-analysis

Demand for organic meat is partially driven by consumer perceptions that organic foods are more nutritious than non-organic foods. However, there have been no systematic reviews comparing specifically the nutrient content of organic and conventionally produced meat. In this study, we report results of a meta-analysis based on sixty-seven published studies comparing the composition of organic and non-organic meat products. For many nutritionally relevant compounds (e.g. minerals, antioxidants and most individual fatty acids (FA)), the evidence base was too weak for meaningful meta-analyses. However, significant differences in FA profiles were detected when data from all livestock species were pooled. Concentrations of SFA and MUFA were similar or slightly lower, respectively, in organic compared with conventional meat. Larger differences were detected for total PUFA and n-3 PUFA, which were an estimated 23 (95 % CI 11, 35) % and 47 (95 % CI 10, 84) % higher in organic meat, respectively. However, for these and many other composition parameters, for which meta-analyses found significant differences, heterogeneity was high, and this could be explained by differences between animal species/meat types. Evidence from controlled experimental studies indicates that the high grazing/forage-based diets prescribed under organic farming standards may be the main reason for differences in FA profiles. Further studies are required to enable meta-analyses for a wider range of parameters (e.g. antioxidant, vitamin and mineral concentrations) and to improve both precision and consistency of results for FA profiles for all species. Potential impacts of composition differences on human health are discussed

Knowledge and skills attractive for the employers of the organic sector: A survey across Europe

In all countries, the organic sector of the agricultural industry is increasing, with Europe traditionally leading this trend. A survey of different stakeholders (employers) was carried out in 2015 in seven European countries to evaluate the employment market for the organic agricultural industry in Europe. Results indicate the willingness to employ qualified graduates. From the employers' perspective, the most desirable knowledge skills among the graduates of organic agricultural studies include plant production, food quality and plant protection. Further, the study revealed the work skills most desired by the employers are practical expertise, teamwork and problem-solving, and the most important method of learning is cooperation with enterprises (internships/training) in the organic agricultural sector.Peer reviewe
