    In this thesis the research focuses on the legal rules and regulations in the Netherlands that apply in the context of food purchases by consumers that are concluded online. Sale of food via the Internet takes place in the area of Civil Code requirements on distance selling and public law requirements on food labelling. In four research Chapters (chapters 2-5) the relevant topics are addressed.

    In Chapter 1 the legal context to the research is presented leading up to the formulation of the central problem statement and the research questions. The Chapter also provides the theoretical framework and the in this research applied methodology.

    Chapter 2 ‘'Real Food from Virtual Shops: the situation before 2014’ reports on research performed before the entry into force of the national implementation of the Consumer Rights Directive and of the Food Information Regulation. This chapter provides the historical baseline to this research. The research in this chapter shows that the instruments handed to the consumers to compensate their weakened position as online buyers, cannot function as intended in case the merchandise is food. It is argued that consumers derive more bite from general provisions of contract law than from the provisions specifically addressing distance contracts.

    In Chapter 3, ‘Food Online, Radical Changes to the Digital Shop Window after 2014’ the argument is continued by addressing in detail the implementation of the Consumer Rights Directive in the Netherlands and the entry into force of the Food Information Regulation. The differences become visible between civil law and public food legislation in the manner in which they envisage to protect the consumer. Civil law turns out to be rather scarce in requiring information provision to consumers. In his attempt to ensure that consumers are only bound to purchase contracts they actually want, the European legislator has chosen a far more draconic instrument. The consumer has been given the right to withdraw from the contract altogether after the etailer has already fulfilled his side of the agreement. The legislature has preferred this instrument over elaborate information requirements regarding the product to be purchased. The available data do not show that the legislature balanced these two instruments.

    Whatever these reasons have been, they seem to have been less compelling in the case of food products. The vast majority of foods is exempted from the consumers' right to withdraw. This leaves a considerable gap in the civil law protection of consumers of food online. This gap has recently been filled by the Food Information Regulation. This regulation does put in place a considerable obligation to supply the consumer online with information prior to the purchase decision. The etailer has to provide online all the information which the producer is required to provide on the food label. In one small provision the entire and complex burden the Food Information Regulation places on the food industry, is placed with the etailer as well.

    In Chapter 4 ‘Product Liability for Online Food Suppliers’ the increased risks for the etailer of foods to become product liable is addressed. Due to the wide scope of the definition of ‘producer’ in product liability law, the risk for the etailer to be considered the liable producer is rather high. Due to the Consumer Rights Directive and its implementation in national law, of all the players in the chain the etailer is easiest to identify for the consumer. Etailers have to push their claims further up the hill without any recourse to facilities regarding burden of proof or liability. Both the Consumer Rights Directive and the Food Information Regulation have been designed to reinforce the consumers’ position with a view to ensuring that consumers will no longer be the weakest link in the value chain.

    In Chapter 5 'The Lucky Bag for Meals' the emerging market for food-boxes is discussed. Food-boxes embody the dream of every etailer. Not the consumers decide what they buy, but the retailers decide what they supply. Business economic advantages of this model in terms of stock management, logistics and marketing are obviously enormous. Apparently an important marketing proposition in this modern day ‘lucky bag’ is the surprise. It appears that consumers want to be surprised. Despite all requirements regarding transparency and information provision imposed by legislators upon the etailer with a view to protecting consumers, a part of the market seems to prefer to be kept uninformed. The chapter shows that a relevant group of consumers is actually willing to pay a price premium to businesses for infringing upon their legal obligations and for being kept out of their rights.

    In Chapter 6 the findings of the research are presented. Besides the answers to the research questions a new series of questions emerge. These openings to further exploration show how the legal field of food online in legal development and legal scholarship is just as young as the technology that sparked its emergence.

    Modern fruit production is not possible without reliable and up-to-date information. In addition, developments of technologies in the field of the internet, sensors, drones and robotics are gaining momentum. Consequently, production is changing radically towards flexible, autonomous and demand-driven business processes, which integrate smoothly in the supply chain. We also refer to this transition as the fourth industrial revolution, or Industry 4.0. This report introduces a roadmap for automation and digitalisation in the fruit industry, which will allow this sector to profit from its own Fruit 4.0.

    In 2013 the Dutch authorities issued a warning against a dietary supplement that was linked to 11 reported adverse reactions, including heart problems and in one case even a cardiac arrest. In the UK a 20-year-old woman, said to have overdosed on this supplement, died. Since according to the label the product was a herbal mixture, initial LC-MS/MS analysis focused on the detection of plant toxins. Yohimbe alkaloids, which are not allowed to be present in herbal preparations according to Dutch legislation, were found at relatively high levels (400–900 mg kg–1). However, their presence did not explain the adverse health effects reported. Based on these effects the supplement was screened for the presence of a β-agonist, using three different biosensor assays, i.e. the validated competitive radioligand β2-adrenergic receptor binding assay, a validated β-agonists ELISA and a newly developed multiplex microsphere (bead)-based β-agonist assay with imaging detection (MAGPIX®). The high responses obtained in these three biosensors suggested strongly the presence of a β-agonist. Inspection of the label indicated the presence of N-isopropyloctopamine. A pure standard of this compound was bought and shown to have a strong activity in the three biosensor assays. Analysis by LC-full-scan high-resolution MS confirmed the presence of this ‘unknown known’ β3-agonist N-isopropyloctopamine, reported to lead to heart problems at high doses. A confirmatory quantitative analysis revealed that one dose of the preparation resulted in an intake of 40–60 mg, which is within the therapeutic range of this compound. The case shows the strength of combining bioassays with chemical analytical techniques for identification of illegal pharmacologically active substances in food supplements.

    Due to the emergence of the Internet of Things, supply chain control can increasingly be based on virtual objects instead of on the direct observation of physical objects. Object virtualization allows the decoupling of control activities from the handling and observing of physical products and resources. Moreover, virtual objects can be enriched with information that goes beyond human observation. This will allow for more advanced control capabilities, e.g. concerning tracking and tracing, quality monitoring and supply chain (re)planning. This paper proposes a control model for object virtualization in supply chain management, which is based on a multiple case study in the Dutch floriculture. It includes a typology of distinct mechanisms for object virtualization, which discerns reference objects and future projections next to the representation of real physical objects. The control model helps to define feasible redesign options for the virtualization of supply chain control. It is also of value as a basis to define the requirements for information systems that enable these redesign options.

    In Nederland kopen we nog betrekkelijk weinig voeding online. De verwachting is dat dit gaat veranderen de komende tijd. De voorlopers bedienen zich niet alleen van moderne media als verkoopkanaal, maar houden er ook een andere mentaliteit op na over ‘het goede eten’. De vlucht die het aanbieden van vleespakketten momenteel neemt, illustreert dit goed.

    Herbal food supplements claiming to reduce weight may contain active pharmacological ingredients (APIs) that can be used for the treatment of overweight and obesity. The aim of this study was to determine whether herbal food supplements for weight loss on the Dutch market contain APIs with weight loss properties. Herbal food supplements intended for weight loss (n = 50) were sampled from August 2004 to May 2013. An HPLC-DAD-MS/MS method was used to screen for the presence of the APIs in herbal supplements. In 24 samples the APIs sibutramine, desmethylsibutramine (DMS), didesmethylsibutramine (DDMS), rimonabant, sildenafil and/or the laxative phenolphthalein were identified 41 times. The presence of these APIs was, however, not stated on the label. The potential pharmacological effects of the detected APIs were estimated using data from reported effective doses of approved drugs. Use of 20 of the 24 herbal food supplements may result in potential pharmacological effects. Furthermore, risk assessment of phenolphthalein, a suspected carcinogen and found to be present in 10 supplements, based on the margin of exposure (MOE) approach, resulted in MOE values of 96–30 000. MOE values lower than 10 000 (96–220) were calculated for the daily intake levels of four out of these 10 supplements in which phenolphthalein was found. However, taking into account that weight loss preparations may be used for only a few weeks or months rather than during a lifetime, MOE values may be two to three orders of magnitude higher. The current study shows that the use of food supplements with sibutramine, DMS, DDMS and/or phenolphthalein could result in pharmacological effects.
