RESUMEN
The current migration assessment requirements regarding safety of plastic food contact materials in Europe (e.g. kitchen utensils, kitchen appliances, packaging, etc.) widely rely on migration testing. According to Annexe V of Regulation (EU) No 10/2011 migration testing requirements consider the specificities of repeated use applications only to a limited extent. Repeated use food contact materials should be tested for three consecutive times at the worst-case contact time and temperature. If diffusion controlled, the migration decreases with increasing number of repeated uses. Compared to single use applications, repeated use food contact materials typically exhibit much shorter contact times, much lower ratios of surface in contact with a given amount of food, and in some cases higher temperatures. Compared to real use, in many cases highly overestimated migration testing result are observed. Overestimation by testing at the beginning of use may be coupled with underestimation at later times. National legislation of the Netherlands on food contact materials has established a classification for repeated use rubber materials based on the R-value indicating whether migration testing is required or not. The R-value considers in more detail specificities of repeated use applications. This publication investigates to which extent it is possible to apply the approach to plastics food contact materials in Europe. It is practically impossible to perform migration tests for various materials by putting them many times in contact with food over a long period of time, typically several years, at several temperatures and areas to food amount ratios migration. Modelling has therefore been used to predict migration from various food contact materials under different repeated use scenarios. Realistic diffusion properties of materials and migrant partitioning behaviour have been assumed to minimise the risk of underestimation.

Protein claims provide guidance to consumers seeking protein-rich foods. Protein claim regulations differ globally, and both Canada and the United States require protein quality assessments. A tripartite workshop identified the need to (i) harmonize, (ii) update existing amino acid composition and digestibility databases, (iii) develop non-animal bioassays, and (iv) evaluate the impact of protein claims on human health. The Protein-Digestibility Corrected Amino Acid Score method is recommended for current regulatory use in Canada.

The analysis of feed composition in terms of ingredients is addressed by Regulation (EC) 767/2009 and is important for detecting economic fraud and for monitoring feed safety. Within the framework of the EU project Feed-code, we developed and internally validated a modular assay, relying on intron polymorphism, for the complete qualitative analysis of the botanical composition of feed and the quantitative determination of six target plant species. Main performance parameters of each module, such as applicability, repeatability, specificity, and limit of detection, were evaluated. The whole assay was applied to a set of feed-like samples and results were in agreement with the expected composition. Application to a large set of compound feed and individual raw materials revealed the occurrence of botanical impurities. When compared with microscopic analysis, the proposed method gave more reliable results. We conclude that the Feed-code prototype, readily upgradable to include more plant species, is worthy of consideration for a full validation through a collaborative trial. Graphical Abstract The modular Feed-code method for the authentication of feed botanical composition.

This paper describes the operation of the European Union Reference Laboratory for Feed Additives (EURL) and its role in the authorisation procedure of feed additives in the European Union. Feed additives are authorised according to Regulation (EC) No. 1831/2003, which introduced a completely revised authorisation procedure and also established the EURL. The regulations authorising feed additives contain conditions of use such as legal limits of the feed additives, which require the availability of a suitable method of analysis for official control purposes under real world conditions. It is the task of the EURL to evaluate the suitability of analytical methods as proposed by the industry for this purpose. Moreover, the paper shows that one of the major challenges is the huge variety of the methodology applied in feed additive analysis, thus requiring expertise in quite different analytical areas. In order to cope with this challenge, the EURL is supported by a network of national reference laboratories (NRLs) and only the merged knowledge of all NRLs allows for a scientifically sound assessment of the analytical methods.

The public-health community views mandatory Front-of-Pack (FOP) nutrition labels and nutritional taxes as promising tools to control the growth of food-related chronic diseases. This paper uses household scanner data to propose an ex-ante evaluation and comparison of these two policy options for the fromage blanc and dessert yogurt market. In most markets, labelling is voluntary and firms display fat labels only on the FOP of low-fat products to target consumers who do not want to eat fat. We here separately identify consumer preferences for fat and for FOP fat labels by exploiting an exogenous difference in legal labelling requirements between these two product categories. Estimates of demand curves are combined with a supply model of oligopolistic price competition to simulate policies. We find that a feasible ad valorem fat tax dominates a mandatory FOP-label policy from an economic perspective, but both are equally effective in reducing average fat purchases.

This study examined the fatty acid (FA) composition of 13 (7 soft and 6 hard) Serbian margarines. Significantly higher amounts of trans fatty acids (TFA) were found in hard margarines (up to 28.84% of total FA), than in soft ones (0.17-6.89%). Saturated FA (SFA) were present with 22.76-51.17%. Oleic acid ranged from 26.78% to 43.78%. The proportion of polyunsaturated FA (PUFA) was 22.15-49.29% in soft margarines, but only 8.02-15.28% in hard margarines, probably due to the hydrogenisation process. The atherogenic and thrombogenic indexes (AI and TI, respectively) in soft margarines were relatively low (AI 0.23-0.63 and TI 0.44-0.97), but in hard margarines AI and particularly TI were high (1.03-1.67 and 1.96-3.04, respectively). These findings suggest that FA composition of Serbian margarines should be improved by replacing atherogenic TFA and SFA with beneficial ones, in order to avoid adverse effects on health. Therefore legislative changes and consumer information are urgently needed.

A health claim on "olive oil polyphenols", namely, hydroxytyrosol and its derivatives, was recently approved by EC Regulation 432/2012. As no official method exists so far for the complete separation of all forms of hydroxytyrosol and tyrosol present in the oil, it is of utmost importance to find a simple, reproducible, and undisputable protocol to protect consumers and avoid unfair competition. In this study two hydrolysis protocols for the complex forms either in the polar fraction of the oil (protocol 1) or directly in the oil (protocol 2) were comparatively applied to a series of extra virgin olive oils. Protocol 1 gave at least 50% higher levels of total hydroxytyrosol and tyrosol. Nevertheless, the minimum amount of 5 mg/20 g oil of phenols was fulfilled only when suitable correction factors were introduced in the calculations to account for the differences in the mass between simple and complex phenols. Changes in the terminology used in the health claim are also proposed.

Different risk evaluation approaches have been used to face oil and hazardous and noxious substances (HNS) spills all over the world. To minimize health risks and mitigate economic losses due to a long term ban on the sale of sea products after a spill, it is essential to preemptively set risk evaluation criteria and standard methodologies based on previous experience and appropriate scientifically sound criteria. Standard methodologies are analyzed and proposed in order to improve the definition of criteria for reintegrating previously contaminated marine marketable resources into the commercialization chain in Europe. The criteria used in former spills for the closing of and lifting of bans on fisheries and harvesting are analyzed. European legislation was identified regarding food sampling, food chemical analysis and maximum levels of contaminants allowed in seafood, which ought to be incorporated in the standard methodologies for the evaluation of the decision criteria defined for oil and HNS spills in Europe. A decision flowchart is proposed that opens the current decision criteria to new material that may be incorporated in the decision process. Decision criteria are discussed and compared among countries and incidents. An a priori definition of risk criteria and an elaboration of action plans are proposed to speed up actions that will lead to prompt final decisions. These decisions, based on the best available scientific data and conducing to lift or ban economic activity, will tend to be better understood and respected by citizens.

BACKGROUND: Food borne diseases claim more lives and are growing public health concerns. Simple preventive techniques such as adoption and adherence to hazard analysis and critical control point (HACCP) policy can significantly reduce this disease burden. Though food screening and inspection are done, the ultimate regulation, Hazard Analysis and Critical Control Point, which is known and accepted worldwide, appears not to be popular among food operators in Ghana. This paper examines the level of awareness of the existence of policy on hazard analysis and critical control point (HACCP) and its adherence to food preparation guidelines among food service providers in Ghana. RESULTS: The results revealed the mean age of food providers as 33.1 years with a standard deviation of 7.5, range of 18-55 years, more females, in full time employment and with basic education. Of the fifty institutional managers, 42 (84%) were senior officers and had worked for more than five years. Education and type of food operator had strong statistically significant relationship with the implementation of HCCP policy and adherence with food preparation guidelines. The enforcement of HACCP policy and adherence with food safety guidelines was led by the Ghana Tourist Board, Public Health officers, and KMA, respectively. While a majority of food operators 373/450 (83.3%) did not know HACCP policy is part of food safety guidelines, staff of food safety law enforcement 44/50 (88%) confirmed knowing that food operators were not aware of the HACCP policy. CONCLUSION: The study documents evidence on the practice of food safety principles or HACCP policy or adherence to food preparation guidelines. Existing food safety guidelines incorporate varying principles of HACCP, however, awareness is low among food operators. The implication is that food production is likely to fall short of acceptable standards and not be wholesome putting consumers at health risk. Repeating this study in rural and urban areas in Ghana is necessary to provide much more evidence to inform food safety guidelines. Further studies on chemical analysis of food and implementing training modules on HACCP policy for food producers and law enforcement agencies may be helpful to improve existing situation.

Previous reports demonstrated wide variations in contributions by EU Member States (MS) to the Rapid Alert System for Food and Feed (RASFF) especially for border notifications, emphasising that MS with major entry points play a vital role in ensuring that EU food imports meet EU standards. To further explore the variation this paper aimed to examine notification practices among MS by comparing the levels of detection as a function of the total food imported and population. RASFF notifications issued between 2003 and 2007 were analysed using descriptive statistics and network analysis for differences in notification practice between MS. Major variations in contributions to the RASFF database were observed, which did not correlate with MS size or population. For the key contrast of ratio: 'border: non-border notifications', variations between 7%:89% were observed for the average monthly contributions and, import tonnage per border notification revealed up to 129-fold differences between MS. In conclusion, wide variations in food safety practice exist between MS, including both number and type of contributions to the RASFF database, with some MS being relatively highly active in the key class of border notifications. These findings should inform EU food safety enforcement policies and practices; and central resource allocations.

Consumption of trans fat has been proven to be harmful to human health. This lipid is found mainly in partially hydrogenated vegetable fat, which is widely used in processed foods. The aim of this study was to analyze official publications on maximum limits for consumption of trans fat and the regulations for its mandatory notification on the nutritional labeling of processed foods in Brazil. Weaknesses in the content of the documents analyzed were found, especially regarding the need for reformulation of both the maximum recommended consumption and the notification of trans fat on nutritional labeling for processed foods. This paper makes suggestions for this reformulation, through which it is sought to help consumers in controlling their trans fat intake and, consequently, in promotion of health.

UNLABELLED: Rice can easily accumulate arsenic (As) into its grain and is known to be the highest As-containing cereal. In addition, the As burden in rice may increase during its processing (such as when cooking using As-polluted water). The health risk posed by the presence of As in cooked rice depends on its release from the matrix along the digestive system (bioaccessibility). Two types of white polished long-grain rice, namely, nonparboiled and parboiled (total As: 202 and 190 µg As kg(-1), respectively), were cooked in excess of water with different levels of As (0, 10, 47, 222, and 450 µg As L(-1)). The bioaccessibility of As from these cooked rice batches was evaluated with an in vitro dynamic digestion process. Rice cooked with water containing 0 and 10 µg As L(-1) showed lower As concentrations than the raw (uncooked) rice. However, cooking water with relatively high As content (≥ 47 µg As L(-1)) significantly increased the As concentration in the cooked rice up to 8- and 9-fold for the nonparboiled and parboiled rice, respectively. Parboiled rice, which is most widely consumed in South Asia, showed a higher percentage of As bioaccessibility (59% to 99%) than nonparboiled rice (36% to 69%) and most of the As bioaccessible in the cooked rice (80% to 99%) was released easily during the first 2 h of digestion. The estimation of the As intake through cooked rice based on the As bioaccessibility highlights that a few grams of cooked rice (less than 25 g dry weight per day) cooked with highly As contaminated water is equivalent to the amount of As from 2 L water containing the maximum permissible limit (10 µg As L(-1)). PRACTICAL APPLICATION: Studies on As bioaccessibility are needed for determining human As intake from rice for use in accurate risk assessments to establish updated legislation regarding maximum level of As in food. High As bioaccessibility from parboiled rice (consumed by the majority of the people in South Asia), and the findings of high As levels in discarded rice gruel (fed to livestock), has implications for human and animal health.
