Key words: VKM, risk assessment, Norwegian Scientific Committee for Food and Environment, Norwegian Food Safety Authority, Norwegian Environment Agency, Biowaste, Compost, Plant health, organic waste, Phytosanitary safety, Biogas, Alien organisms Introduction The Norwegian Food Safety Authority (NFSA) and the Norwegian Environment Agency (NEA) have jointly asked the Norwegian Scientific Committee for food and environment for an assessment into treatment methods and validation methods for compost and digestate based on organic waste in relation to plant health and the spread of harmful alien organisms in Norway. The Norwegian Food Safety Authority will use the report in its supervisory work over companies that produce compost and digestate. The assessment will also provide important input for the regulatory development of several current regulations including regulations on indicator organisms that are used to validate new methods and ensure adequate security with regards to the survival of plant pests. The Norwegian Environment Agency wants to establish whether the methods used in the composting of garden waste and other types of plant waste today are able to ensure that the finished product does not become a source for the spread of harmful alien organisms. This will form the basis for the Norwegian Environment Agency’s guidelines relating to the precautionary provisions in the regulation on alien organisms. This request is limited to an assessment of plant pests and harmful alien organisms (hereinafter alien organisms). The survival of infectious diseases harmful to people and animals is considered in separate assessments. Methods We have conducted initiating workshops for identifying relevant fundamental processes and parameters, of relevant organisms and of relevant search terms for the literature surveys, as well as for discussion and validation. Visits to composting facilities and contact with stakeholders in Norway were also conducted. This information was further implemented in an extensive literature search. This assessment include/encompass organic waste and other materials that are currently treated in biogas and composting facilities, including garden and park waste (incl. soil), plant waste from garden centres, etc., food waste and waste from the food and animal feed industry (including grain/seed husks and waste from enterprises which package and process potatoes and vegetables), manure, bulking agents used in composting facilities, and husks from contracted grain/seed cleaners for sowing. We have used a quantitative risk assessment. The level of confidence in the risk assessment is described, and uncertainties and data gaps identified. Furthermore, we have used re-submission commenting and external expert reviewing before final approval and publication. ...........

Berries represent one of the most important and high-valued group of modern-day health-beneficial “superfoods” whose dietary consumption has been recognized to be beneficial for human health for a long time. In addition to being delicious, berries are rich in nutrients, vitamins, and several bioactive compounds, including carotenoids, flavonoids, phenolic acids, and hydrolysable tannins. However, due to their high value, berries and berry-based products are often subject to fraudulent adulteration, commonly for economical gain, but also unintentionally due to misidentification of species. Deliberate adulteration often comprises the substitution of high-value berries with lower value counterparts and mislabeling of product contents. As adulteration is deceptive toward customers and presents a risk for public health, food authentication through different methods is applied as a countermeasure. Although many authentication methods have been developed in terms of fast, sensitive, reliable, and low-cost analysis and have been applied in the authentication of a myriad of food products and species, their application on berries and berry-based products is still limited. The present review provides an overview of the development and application of analytical chemistry methods, such as isotope ratio analysis, liquid and gas chromatography, spectroscopy, as well as DNA-based methods and electronic sensors, for the authentication of berries and berry-based food products. We provide an overview of the earlier use and recent advances of these methods, as well as discuss the advances and drawbacks related to their application.

Denne rapporten presenterer resultater fra fem flerårige feltforsøk med avløpsslam, det ene med resultater fra ti år. Formålene med forsøkene var å bedre kunnskapen om plantetilgjengelighet av fosforet i slammet og å undersøke den mulige miljøeffekten av å tilføre slam til jordbruksarealer. Resultatene viser at kalket avløpsslam kan gi en betydelig økning i jordas innhold av lett løselig fosfor, mens ukalkede slamtyper hadde enten ingen effekt eller en tendens til negativ effekt på innholdet av lett løselig fosfor. Avløpsslam hadde en positiv, men kortvarig effekt på jordstruktur og kan dermed redusere erosjon den første tiden etter tilførsel. Resultater fra et avrenningsforsøk viste at slam som gir økning i jordas P-AL-nivå, ga en større andel løst fosfat i overflateavrenningen. Det ble funnet økt konsentrasjon av tungmetallene sink og kobber i kornet første året etter slamtilførsel.
