Resveratrol food supplement products and the challenges of accurate label information to ensure food safety for consumers
Maja Bensa, Irena Vovk, Vesna Glavnik, 2023, izvirni znanstveni članek

Opis: The food supplement market is growing as many consumers wish to complement their nutrient intake. Despite all the regulations in place to ensure food supplements safety, there are still many cases of irregularities reported especially connected to internet sales. Twenty resveratrol food supplement products sold on the Slovenian market were evaluated on their compliance of declared vs. determined resveratrol content, as well as the compliance of labels with the European Union (EU) and Slovenian regulatory requirements. Both the ingredient contents and food information are important parts of food safety. Analyses of 20 food supplements performed using high-performance thin-layer chromatography (HPTLC) coupled with densitometry showed that 95% of products had contents different from what was declared and 55% of products contained higher contents than declared. In 25% of the products the determined content per unit exceeded the maximum level (150 mg/day) specified in EU novel food conditions for food supplement with trans-resveratrol. Evaluation of the 20 food supplement labels included mandatory and voluntary food information, food supplement information, novel food information, health claims and nutrition claims. Most labels contained the necessary information, but multiple errors were observed ranging from typos to misleading practices. From a food safety perspective there is still a lot of improvement needed in the field of food supplements.

Food risk analysis : Towards a better understanding of “hazard” and “risk” in EU food legislation
Ana-Andreea Cioca, Livija Tušar, Tomaž Langerholc, 2023, izvirni znanstveni članek

Opis: For risk communication, it is important to understand the difference between “hazard” and “risk”. Definitions can be found in Codex Alimentarius and the European Union (EU) General Food Regulation (EC) No. 178/2002. The use of these terms as synonyms or their interchange is a recurrent issue in the area of food safety, despite awareness-raising messages sent by EFSA (European Food Safety Authority) and other interested entities. A quick screening of the EU’s food regulations revealed several inconsistencies. Hence, it was considered necessary to further investigate if regulations could act as a source for this problem. A software tool was developed to support the detection and listing of inconsistent translations of “hazard” and “risk” in certain EU food regulations. Subsequently, native-speaking experts working in food safety from each EU country were asked to provide their individual scientific opinion on the prepared list. All data were statistically analysed after applying numerical scores (1–5) describing different levels of consistency. Results showed that the most common problem was the interchange of “hazard” with “risk” and vice versa. This lack of consistency can create confusion that can further translate into misjudgments at food risk assessment and communication levels.

Nanotechnology in food safety and quality assessment : potentiality of nanoparticles in diagnosis of foodborne pathogens
Maša Pintarič, 2016, pregledni znanstveni članek

Opis: A rapid microbial detection in different biological and environmental material is a key of preventing several foodborne diseases. By implementing nanotechnology into food safety sector, a great step towards successful, reliable and sensible detection methods of foodborne pathogens has been achieved. Therefore, the aim of this review was to illustrate some of the principal functions of nanotechnology-based techniques, used for microbial detection in the last few years. Regarding consumer’s health, the review also discusses the question of safety, concerning human exposure to nanomaterials (NMs). Due to their different composition-unique properties, such as greater penetrability, reactivity and high surface to volume ratio, NMs have been coupled to several biomolecules and integrated in special system devices, resulting in improvement of sensitivity in transmitting biological signal informations in a shorter time. Among all the NMs, gold, magnetic and fluorescent nanoparticles (NPs) have been widely used, also in microbial diagnosis. Despite the success of linking nanotechnology to detection of foodborne pathogens, the exposure to various NMs could also be a matter of potential risk to human health, although conclusions still need to be definitely proven.

A Short review of chain controlling systems in livestock production technology
Dejan Škorjanc, Maksimiljan Brus, Igor Vojtic, 2005, pregledni znanstveni članek

Opis: There is a general agreement that the main reason for domestication was to provide a reliable source of food protein. Wild animals were hunted for thousands of years, killed for meat, wool, fur, and liquid by our predecesors.This one-way relationship between humans and animals was changed much later, during domastication and until know, the men took responsibility for animals and changed and developed different production system and ethical relationship with animals. After Second World War, the governments tried to change so called traditional agriculture to more intensive. Animals have been kept in high concentration and for the continuous production as a consequence,disease control became essential. European Union issued the paper on food safety (White paper on food safety 2000) where the EU commission triedto push forward a framework of legislation for further improvement and to develope more transparent and improved quality standards throughout a food chain from farm to table. This paper reviews a number of recent developments, starting with an integrated quality control system that collecting important data from the animal birth, through to the animal rearing phase to the end (i.e. slaughter). The importance of Hazard Analysis Critical Control Point (HACCP) is discussed together with their concepts to assure safe animal food production.
