Following a request from the European Commission, the EFSA Panel on Nutrition, Novel Food and Food Allergens (NDA) was asked to deliver an opinion on the safety of frozen and dried formulations from house crickets (Acheta domesticus) as a novel food pursuant to Regulation (EU) 2015/2283. The NF is proposed in three formulations: (i) frozen, (ii) dried, (iii) ground. The main components of the NF are protein, fat and fibre (chitin) in the dried form of the NF, and water, protein, fat and fibre (chitin) in the frozen form of the NF. The Panel notes that the concentrations of contaminants in the NF depend on the occurrence levels of these substances in the insect feed. The Panel further notes that there are no safety concerns regarding the stability of the NF if the NF complies with the proposed specification limits during its entire shelf‐life. The NF has a high‐protein content, although the true protein levels in the NF are overestimated when using the nitrogen‐to‐protein conversion factor of 6.25, due to the presence of non‐protein nitrogen from chitin. The applicant proposed to use the NF in the form of a snack, and as a food ingredient in a number of food products. The target population proposed by the applicant is the general population. The Panel notes that, considering the composition of the NF and the proposed conditions of use, the consumption of the NF is not nutritionally disadvantageous. The Panel notes that no genotoxicity and no subchronic toxicity studies with the NF were provided by the applicant. Considering that no safety concerns arise from the history of use of A. domesticus or from the compositional data of the NF, the Panel identified no other safety concerns than allergenicity. The Panel considers that the consumption of the NF might trigger primary sensitisation to A. domesticus proteins and may cause allergic reactions in subjects allergic to crustaceans, mites and molluscs. Additionally, allergens from the feed may end up in the NF. The Panel concludes that the NF is safe under the proposed uses and use levels.

Following a request from the European Commission, the EFSA Panel on Nutrition, Novel Foods and Food Allergens (NDA) was asked to deliver an opinion on frozen and dried formulations from whole yellow mealworm (Tenebrio molitor larva) as a novel food (NF) pursuant to Regulation (EU) 2015/2283. The term yellow mealworm refers to the larval form of the insect species Tenebrio molitor. The NF comprises the frozen and freeze-dried formulations of the yellow mealworm, whole or in the form of powder. The frozen formulation consists mainly of water, crude protein and fat whereas the freeze-dried formulations of crude protein, fat, digestible carbohydrates and fibre (chitin). The Panel notes that the levels of contaminants in the NF depend on the occurrence levels of these substances in the insect feed. The Panel notes furthermore that there are no safety concerns regarding the stability of the NF if the NF complies with the proposed specification limits during its entire shelf-life. The dried formulations of the NF have a high protein content, although the true protein levels in the NF are overestimated when using the nitrogen-to-protein conversion factor of 6.25, due to the presence of non-protein nitrogen from chitin. The applicant proposed to use the NF as whole frozen or whole dried insect, or in the form of powder, added as an ingredient to various food products such as cereal bars, pasta, meat imitates and bakery products. The target population is the general population. The Panel notes that, considering that the NF will not be the sole source of dietary protein, and the composition of the NF and the proposed conditions of use, the consumption of the NF is not nutritionally disadvantageous. The submitted toxicity studies from the literature did not raise safety concerns. The Panel considers that the consumption of the NF may induce primary sensitisation and allergic reactions to yellow mealworm proteins and may cause allergic reactions in subjects with allergy to crustaceans and dust mites. Additionally, allergens from the feed may end up in the NF. The Panel concludes that the NF is safe under the proposed uses and use levels. (C) 2021 European Food Safety Authority.

Following a request from the European Commission, the EFSA Panel on Nutrition, Novel Foods and Food Allergens (NDA) was asked to deliver an opinion on the extension of use of galacto-oligosaccharides (GOS) as a novel food (NF) pursuant to Regulation (EU) 2015/2283. The NF is a syrup containing >= 57% w/w GOS (w/w dry matter), consisting of different galactosyl residues linked to a terminal glucose by a beta-glycosidic bond and also containing lactose and the constituent monomers of lactose (galactose and glucose). The NF is already authorised and included in the Union list of NFs and is produced according to the same production process. This application is limited to an assessment of the extension of use as a food ingredient in dairy confectionary, cheese and processed cheese, butter and spreads. There is a 10-30% increase in total GOS intake from the requested extension of use compared to the currently authorised uses at the highest 95th percentile. It is noted that the total intake at the highest mean (8.7-22.0 g/day) is below the adequate intake (AI) of 25 g/day for dietary fibre set to ensure a normal laxation in adults, while the highest 95th percentile (27.2-41.6 g/day) is higher than the AI. When the maximum use as a food supplement is added to the highest 95th percentile combined intake from all proposed and authorised food categories a total intake up to 58 g GOS/day is estimated. This highest intake level would exceed the AI for dietary fibre; however, no tolerable upper intake level for dietary fibre has been set and only transient gastrointestinal symptoms may be related to high intake of fibre. The Panel concludes that the NF, that is composed of >= 57% GOS dry matter, lactose and related saccharides, is safe under the proposed extension of use. (C) 2021 European Food Safety Authority.

Following a request from the European Commission, the EFSA Panel on Nutrition, Novel Foods and Food Allergens (NDA) was asked to deliver an opinion on mung bean protein as a novel food (NF) pursuant to Regulation (EU) 2015/2283. The NF, which is the subject of the application, is mung bean protein extracted from seeds of the plant Vigna radiata. The NF is proposed to be used as a food ingredient added to 'protein products, excluding products covered in category 1.8'. The target population is the general population. The maximum estimated intake of the NF is 758 and 260 mg/kg body weight (bw) per day in children and adults, respectively. The major constituents of this NF are protein (similar to 85%), fat (3-4%) and moisture (3-5.5%). The NF is rich in protein which is well digestible and provides sufficient amounts of most essential amino acids but only limited amounts of sulfu-rcontaining amino acids. The Panel notes that the cumulative exposure to the minerals analysed does not raise concern. The reported values for the levels of antinutritional factors in the NF are comparable to those in other foodstuffs. The Panel considers that taking into account the composition of the NF and the proposed conditions of use, consumption of the NF is not nutritionally disadvantageous. No toxicological studies with the NFs were provided by the applicant; however, the Panel considers that no toxicological studies are required on this NF. This NF has the potential capacity to sensitise individuals and to induce allergic reactions in individuals allergic to soybean, peanuts, lupin and to birch pollen. The Panel considers that the NF, i.e. mung bean protein, is safe at the proposed conditions of use. (C) 2021 European Food Safety Authority.

Following a request from the European Commission, the EFSA Panel on Nutrition, Novel Foods and Food Allergens (NDA) was asked to deliver an opinion on pasteurised Akkermansia muciniphila as a novel food (NF) pursuant to Regulation (EU) 2015/2283. A. muciniphila is a well-characterised non-toxin producing, avirulent microorganism that has been reported as part of normal gut microbiota. The NF, pasteurised A. muciniphila, is proposed by the applicant to be used as a food supplement at max. 5 x 10(10) cells/day by adults excluding pregnant and lactating women, and in foods for special medical purposes. The Panel considers that the production process of the NF is sufficiently described and that the information provided on the composition of the NF is sufficient for its characterisation. Taking into account the composition of the NF and the proposed conditions of use, the consumption of the NF is not nutritionally disadvantageous. Based on literature data, and by applying an uncertainty factor of 200 to the no observed adverse effect level (NOAEL) of a 90-day repeated dose oral toxicity study in rats, the Panel concludes that the consumption of 3.4 x 10(10) cells/day is safe for the target population under the provision that the number of viable cells in the NF is < 10 colony forming units (CFU)/g (i.e. limit of detection).

There is a growing call (and agreement) to transform food systems towards sustainable, just and healthy systems, understanding that transformation is about fundamental, system- wide changes, beyond piecemeal interventions (see Box 1 for the new FACCE-JPI approach to food systems). But, what does transformation look like? Is there a consensus about what we want to transform in food systems, who will do it and how? The objective of this policy brief is to call for fairer, more inclusive and eventually, more effective decisions on food systems transformations. For doing so, it focuses on decision-making under uncertainty, highlighting complexity and framings as two components of this: On one hand complexity requires us to avoid oversimplification of messages (see the livestock section) and on the other, framing calls for the integration of a plurality of values and worldviews (see the governance section). Thus, in the context of the UNFSS objective of transforming food systems, this brief aims to raise awareness of decision makers about the need of developing and using knowledge and tools that i) tackle the complexity of food systems as complex social-ecological systems, and ii) recognise the existence of different framing and values in a context of uncertainty. We also reflect on the role of science in this process. While our focus is global, we focus on Europe to exemplify our arguments. Yet, transformation cannot happen in one world region independently from the others. A global movement requires first adopters to start the process.

Parasites threaten human and animal health globally. It is estimated that more than 60% of people on planet Earth carry at least one parasite, many of them several different species. Unfortunately, parasite studies suffer from duplications and inconsistencies between different investigator groups. Hence, groups need to collaborate in an integrated manner in areas including parasite control, improved therapy strategies, diagnostic and surveillance tools, and public awareness. Parasite studies will be better served if there is coordinated management of field data and samples across multidisciplinary approach plans, among academic and non-academic organizations worldwide. In this paper we report the first 'Living organism-World Molecular Network', with the cooperation of 167 parasitologists from 88 countries on all continents. This integrative approach, the 'Sarcoptes-World Molecular Network', seeks to harmonize Sarcoptes epidemiology, diagnosis, treatment, and molecular studies from all over the world, with the aim of decreasing mite infestations in humans and animals. © 2011 International Society for Infectious Diseases.

Tiivistelmä. Tämä pro gradu -tutkielma on osa Oulun yliopiston oppikirjaprojektia, jonka tarkoituksena on tuottaa käytössä olevan, vuonna 2016 käyttöön otetun opetussuunnitelman mukaista avointa oppimateriaalia lukion matematiikan kursseille. Oppikirjaprojektiryhmä on työstänyt materiaalia lukion MAA5 Analyyttinen geometria -kurssille ja tämä tutkielma kattaa kyseisen kurssin aiheista osiot suora ja suorien keskinäinen asema. Suorasta käsitellään eri muotoiset suoran yhtälöt ja millaisia eri esityksiä on kuvailla suorien ominaisuuksia. Suorien keskinäinen asema -kappaleessa keskitytään suorien leikkauspisteisiin, milloin niitä on ja milloin ei, suorien väliseen kulmaan sekä kohtisuoruuteen. Perustana tutkielmalle on lukion opetussuunnitelma, mutta myös ajatus kehittyvästä matematiikan oppimisesta ja opetuksesta. Tarkoitus on tuottaa aikaa kestävää materiaalia, joka kehittää opiskelijoiden ajattelua ja kykyä ratkaista ongelmia sekä monipuolista kykyä hallita digitaalisia työkaluja. Tutkielma koostuu oppimateriaalin lisäksi perusteluosiosta, opettajan oppaasta sekä harjoitustehtävien vastauksista. Perusteluosassa tieteellisiin artikkeleihin nojaten perustellaan valitut tehtävät sekä muut valinnat, joita oppimateriaalissa on tehty, kuten yhteisesti projektiryhmän kanssa valitut tehtävätyypit ja ajatusmallit, joita kirja mukailee. Oppimateriaalin runkona toimii pohdintatehtävät, joiden tarkoitus on kehittää opiskelijoiden matemaattista ajattelua ja ongelmanratkaisukykyä ollen avoimia tai ongelmalähtöisiä tehtäviä. Harjoitustehtävät tukevat pohdintatehtäviä ja teoriaa molempien kappaleiden lopuksi. Opettajan oppaassa oppimateriaalin ajankäyttöön on annettu suuntaa antava ohjeistus ja annettu pohdintatehtävistä esiin nousevia huomioita, jotka tukevat opettajaa oppimateriaalin käytössä. Pohdintatehtävien vastaukset on myös annettu opettajan oppaassa. Harjoitustehtävien vastaukset löytyvät tutkielman lopuksi. Tutkielmassa keskitytään opiskelijalähtöisiin tehtäviin ja siihen, että oppimateriaali ohjaisi opiskelijoita itsenäiseen ajatteluun ja kehittämään ongelmanratkaisukykyään. Tutkimuksissa löydettyihin ongelmakohtiin tai virhekäsityksiin pyritään puuttumaan tehtävillä, jotka ohjaisivat opiskelijoita pois kyseisistä ongelmista tai virhekäsityksistä ja tukevat heidän matemaattista ajatteluaan. Tehtävien tukena, tai joissain tapauksissa jopa pääroolissa, käytetään GeoGebra-ohjelmaa, joka auttaa opiskelijoita havainnollistamaan visuaalisesti algebrallisia ongelmia.
