| The Cd content of the seed samples varied between 0,27 and 1,3 mg/kg dry matter. The Cd contents of the crush samples were 56 % higher on average than those of the corresponding seeds. The content of alfa-linolenic acid of the Finnish samples was among the highest compared with results from several international studies (reference value 57,0 %, Morris 2003). The composition of fatty acids, especially unsaturated fatty acids, reported in different studies varies considerably. This variation depends mainly on differences in the examined varieties and in industrial processing treatments. |

| Structural change in agriculture means a continuous need for investing in farm production. It is essential for the sustainable operations and the economy of the farm that such investments are successful. In this research, different stages of the investment process of farms were studied as well as the use of information and the success perceived during the investment process. The study was carried out with mail surveys and telephone interviews on the Finnish Farm Accountancy Data Network (FADN) farms. The most challenging investments were in animal husbandry buildings and, as to these investments, the comparison of alternatives was the most challenging stage. For most investments, the planning phase was considered more challenging than the implementation.... |

| In this review the quality properties of linseed oil for food uses are discussed as well as factors affecting this quality. Linseed oil has a favourable fatty acid composition with a high linolenic acid content. Linseed oil contains nearly 60% á-linolenic acid, compared with 25% for plant oils generally. The content of linolenic acid and omega-3 fatty acids is reported to be high in linseed grown in northern latitudes. The composition of fatty acids, especially unsaturated fatty acids, reported in different studies varies considerably for linseed oil. This variation depends mainly on differences in the examined varieties and industrial processing treatments. The fatty acid composition leads also to some problems, rancidity probably being the most... |

| The aim of this study was to screen the cadmium (Cd) contents of seed and seed crush of Finnish linseed and to evaluate the acceptable daily dose. The Cd content of Finnish linseed is of interest, since some properties of linseed as the content of fatty acids are different in northern growth locations compared with other growing areas. Seed samples (N = 85) were collected from the experimental farm of Helsinki University and from commercial fields in different locations in southern Finland and Ostrobothnia. In addition, 15 samples of linseed crush were examined. The cadmium contents of the linseed samples, determined with atomic absorption spectroscopy, varied between 0.27 and 1.3 mg kg-1 (dry weight) (mean 0.61 mg kg-1). The Cd contents of the crush... |

| Microbiological dipslides are widely used e.g. in food production facilities for HACCP (hazard analysis & critical control points) measurements and hygiene monitoring surveys, as well as for other cleanability studies. In this study the suitability of microbiological dipslide methods to measure the hygiene level of the environmental surfaces in a cattle barn was tested. A total of 1112 measurements were carried out during five measurement days. When evaluating the rooms by combining the results of the individual sampling sites and different dipslide types (total microbes, enterobacteria and β-glucuronidase-positive organisms, yeasts and moulds), the corridor and personnel rooms had the highest hygiene status. The office and personnel kitchen and... |
