Knowledge, practices and perceptions of energy labelling of nut products among Australian consumers and stakeholders: an online survey.

Nut consumption in Australia is low, perhaps due to concerns with weight gain. However, nut consumption is not associated with increased weight, in part because of their lower metabolisable energy. Current energy labelling for nuts use Atwater factors, which over-represent the available energy from nuts. Therefore, this research aimed to examine stakeholders' knowledge, practices and perceptions of displaying true metabolisable energy on nutrition labels and its perceived impact on nut consumption. An anonymous and voluntary survey was conducted online. Eligible respondents lived in Australia, were aged 18 years or older and had either no formal nutrition education (consumer group) or had formal training and were working as a stakeholder (stakeholder group; working in nutrition/dietetics, public health, food industry, food regulation or nut growing). Convenience sampling and snowballing were used to recruit respondents primarily via online advertisement. Three hundred and forty-eight respondents (63.2% female; 71.0% aged 18-39 years; 69.0% Bachelor's degree or higher) were included in the analyses. A larger proportion of stakeholders agreed that nut consumption assists with weight management (67.9%) compared with consumers (47.6%). Theoretical food packaging showing both Atwater and metabolisable energy in the nutrition information panel was favoured among consumers and stakeholders, though 62.3% of consumers reported that a lower metabolisable energy of nuts would not impact their consumption. This study indicates a need to further investigate the impact of metabolisable energy labelling on nut intake. Further education about the relationship between nuts and body weight is required for consumers and stakeholders.

Isolation and purification of lactic acid bacteria and yeasts based on a multi-channel magnetic flow device and rapid qualitative and quantitative detection

Rapid isolation and identification of lactic acid bacteria and yeasts during fermentation is of great significance for quality control and regulation of fermented foods. In this study, we prepared a multi-channel magnetic flow device for rapid separation and purification of lactic acid bacteria and yeast, and based on SERS spectrum, we made rapid qualitative and quantitative analysis of Lactobacillus plantarum, Lactococcus lactis and Saccharomyces cerevisiae. The results showed that the synthesized Synthesized Fe3O4-Van antibiotic magnetic beads are paramagnetic; Fe3O4-Van antibiotic magnetic beads achieved capture efficiencies of more than 98.5 % for both L. plantarum and L. lactis at 102–104 CFU/mL, respectively. Separation and purification efficiency of single S. cerevisiae, L. plantarum and L. lactis by multi-channel magnetic flow device all reached more than 98 % with good isolation and purification results. The SERS spectra of the three microorganisms were classified and analyzed using linear discriminant analysis (LDA), and the accuracy of the established LDA model was 100 %, which completely differentiated the SERS spectra of the three microorganisms,and realized the qualitative identification of L. plantarum, L. lactis, and S. cerevisiae, and finally, quantitative model was established with the logarithmic values (lg C) of different concentrations of L. plantarum, L. lactis, and S. cerevisiae as the horizontal coordinates, and the Raman intensities at their strongest characteristic peaks of 512 cm−1, 1669 cm−1, and 1125 cm−1, respectively, were used as vertical coordinates to establish a quantitative model, with the lowest detection limit of 10 CFU/mL, and the digital quantification of lactic acid bacteria and yeast were achieved. It provided an effective means for real-time monitoring and tracking of the dynamics of lactic acid bacteria and yeast in the fermentation process and the quality control of fermented foods.

Understanding the Politics of Food Regulation and Public Health: An Analysis of Codex Standard-Setting Processes on Food Labelling

Background: The importance of the international food regulatory system to global health, is often overlooked. There are calls to reform this system to promote healthy and sustainable food systems centred on the Codex Alimentarius Commission (Codex), the United Nation’s (UN’s) standard-setting body. Yet this presents a significant political challenge, given Codex has historically prioritized food safety risks over wider harms to public health, and is dominated by powerful food exporting nations and industry groups with a primary interest in trade expansion. To better understand this challenge, we examine who participates and contests Codex standards, using the development of the new Guidelines on Front-of-pack Nutrition Labelling (FOPNL) as a case study. Methods: The study involved: (i) collecting Codex Committee on Food Labelling (CCFL) documents (2016-2023); (ii) identification, categorization, and enumeration of actors involved in the development of the Guidelines; and (iii) guided by a constructivist framework, analysis of how actors framed and contested key provisions of the Guidelines. Results: Country representation was skewed towards high-income (47.9%). Member state delegations were dominated by non-health ministries (59.8%) and industry actors (16.1%). Industry actors comprised the large majority of observers (84.2%) and civil society actors representing public health interests the least (12.2%). Commercial actors used frames supporting positive FOPNL messages (eg, low in salt) opposing negative ones (eg, "high-in" sugar warnings) and called for product exemptions (eg, sports foods and baby foods). Public health actors used frames supporting simplified FOPNL to reduce consumer confusion, that hold up public health goals, and prevent inappropriate marketing. Conclusion: Participation in the Guidelines development process suggests stronger preferences for trade facilitation and commerce over public health. Ambitions to reform the international food regulatory system may require an examination of who participates and how to address this asymmetrical representation of interests. These results suggest the need to greatly strengthen public health representation at Codex.

Updated Risk Assessment of Cannabidiol in Foods Based on Benchmark Dose–Response Modeling

Cannabidiol (CBD), a non-psychotropic main component of the Cannabis plant, has been approved as a drug in the European Union (EU) under the name “Epidyolex”. However, its approval process as a food ingredient under the Novel Food Regulation was paused by the European Food Safety Authority (EFSA) due to a lack of safety data. Nevertheless, there is a growing, unregulated market in which CBD is advertised with various health claims and dosage instructions. Of particular concern is its toxic effect on the liver and possible reproductive toxicity in humans. Studies suitable for calculating the benchmark dose were identified from the available data. Animal studies yielded a benchmark dose lower confidence limit (BMDL) of 43 mg/kg bw/day, which translates into a safe human dose of approximately 15 mg/day. Only the Lowest-Observed-Adverse-Effect Level (LOAEL) of 4.3 mg/kg bw/day could be identified from the human data. This updated risk assessment confirmed a health-based guidance value (HBGV) of 10 mg/day based on human LOAEL. Despite the existing data gaps, preliminary regulation appears advisable because the current form of the gray CBD market is unacceptable from the standpoint of consumer safety and protection.

Commercial determinants of health and cancer prevention in South Africa

Aim Commercial determinants, encompassing marketing strategies, corporate social responsibility, and lobbying, significantly contribute to avoidable cancer deaths globally. In South Africa, 30-50% of cancers are preventable, but SA focuses mainly on tobacco control, ignoring major causes of cancer such as alcohol, obesity, and ultra-processed foods. This paper highlights the role of these commercial determinants in contributing to cancer in SA. It outlines strategies and barriers in addressing these determinants. Approach While conventional approaches focus on individual responsibility relating to risk factors like tobacco, alcohol, and unhealthy diets, the role of industries in promoting these risk factors remains inadequately addressed. The paper explores the marketing and non-marketing methods employed by industries, such as tobacco, alcohol, and ultra-processed products, to maximise profits while neglecting public health consequences. Findings The article sheds light on industry tactics, including strategic partnerships, sponsorship, and diversionary narratives during crises, aimed at safeguarding profits. It emphasises the less-explored realm of non-marketing strategies, such as political lobbying, industry-funded research, and the ‘revolving door’ phenomenon where industry insiders become policymakers. Conclusions The article advocates for a paradigm shift in cancer prevention policies, urging the government to implement a comprehensive suite of measures that include increased taxation on harmful products, strict restrictions on marketing, enhanced product labelling, and eliminating conflict of interest in health research and policies. Addressing the commercial determinants necessitates not only recognising their impact but also adopting a multi-level governance approach that prioritises public health over corporate profits. The paper concludes by emphasising the urgency of recognising the links between alcohol, food regulation, and cancer prevention. The overarching goal is to shift power relations, fostering governance for the collective good and ensuring equitable access to preventive measures, especially for vulnerable populations.

Process optimization and modeling of Acer truncatum seed oil deacidification by molecular distillation

Acer truncatum seed oil (ATO) is a unique woody oil resource, but its high acid value resulting from traditional pressing methods falls short of meeting the necessary food standards. In this research, molecular distillation (MD) was employed for the deacidification of ATO and compared with conventional techniques such as alkali refining and solvent extraction. Predictive models for MD deacidification were established through single-factor experiments, orthogonal experimental design (OED), response surface methodology (RSM), and genetic algorithm - back propagation artificial neural network (GA-BP-ANN). Using RSM, a fitting model was obtained with R = 0.999 and Rpre = 0.990 through multiple linear regression. The constructed BP-ANN model (3-9-1) exhibited R = 0.998 and Rpre = 0.998, indicating slightly higher prediction accuracy. With GA-BP-ANN, the optimal process conditions are an evaporator temperature of 190 °C, condensation temperature of 40 °C, scraper speed of 324 rpm, yielding an acid value of refined ATO at 0.240 ± 0.001 mg g−1. Therefore, under appropriate conditions, the MD deacidification method can produce high-quality refined ATO. The developed orthogonal, RSM, and GA-BP-ANN models demonstrated excellent capabilities in optimizing and predicting the MD deacidification process, meeting even the strictest food regulations.

Risk-benefit assessment of foods and its role to inform policy decisions: outcome of an international workshop.

Policy decisions in public health require consideration and evaluation of trade-offs for which transparency and science-based evidence is needed. Improvement of decision-support tools is essential to help guide food policy decisions that promote healthy diets and meet the challenges of food systems without compromising food security, food safety, and sovereignty. Risk-benefit assessment of foods (RBA) is an established methodological approach designed to inform policy decisions within the area of nutrition and food safety. Despite methodological developments, translation of RBA findings into policies is still limited. In this context, a stakeholder workshop held in May 2023 gathered RBA experts and food regulators from Europe to identify the challenges, obstacles and opportunities in using evidence generated through RBAs to inform food policy decisions. A structured process was implemented to collect their views through online surveys, breakout groups, and plenary discussions. As a secondary objective, food regulators' views on other approaches for holistic risk assessment fit for food systems analysis were also explored. This paper summarizes the main findings of the workshop and discusses policy implications and future perspectives to improve the area of RBA and its role in food policymaking.

Enhanced Surveillance of >1100 Pesticides and Natural Toxins in Food: Harnessing the Capabilities of LC-HRMS for Reliable Identification and Quantification

The consequences of climate change along with diverse food regulations and agricultural practices worldwide are complexifying the occurrence and management of chemical contaminants in food. In this context, we present an ultra-high-performance liquid chromatography high-resolution mass spectrometry (LC-HRMS) approach for the simultaneous identification and quantitation of over 1100 pesticide residues, mycotoxins, and plant toxins in cereals and fruits and vegetables. Analytical conditions were optimized to maximize the scope of the targeted molecules, the reliability of compound identification, and quantification performance within a single method. The method was further transferred and validated in another laboratory to assess its ruggedness. Validation according to the SANTE 11312/2021v2 guidelines showed that 92% and 98% of the molecules fulfill the quantification criteria at the lowest validated level in the cereals and fruits and vegetables groups, respectively. Analysis of fifteen certified reference materials led to a 96% satisfactory rate of z-scores confirming method’s competitiveness. Furthermore, the occurrence of these contaminants was studied in 205 cereals and grains samples collected worldwide. The low µg/kg quantification limits make this LC-HRMS method a valuable tool to ensure compliance toward regulations and to screen for non-regulated substances for which occurrence data are crucial for an appropriate risk evaluation.

Correlation of Diabetes self-care adherence with glycemic measures: a cross-sectional health facility-based study in Kathmandu, Nepal

Self-care plays a key role in prevention of complications, and improvement of the quality of life of persons with diabetes (PWDs). This study has assessed adherence to self-care behavior and its correlation with glycemic measures among PWDs attending private health care facilities in Kathmandu, Nepal. A cross-sectional study was carried out using a semi-structured questionnaire. Socio-demographic information and recent fasting (FBG) and 2-hr post-prandial blood glucose (2-hr PBG) levels were recorded. Self-care inventory (SCI) 12-item version was used to assess adherence to diabetes self-care over the preceding four weeks. Self-care practice was measured in five domains: glucose monitoring; diabetes medication; diet; exercise; and preventative care. The overall adherence score was obtained by computing the average of seven items (items 1, 2, 4, 5, 6, 7, 14). Scores more than or equal to median score were considered as higher levels of self-care efficacy. Univariate linear regression analysis of the subscale scores and individual item-wise score with age, duration of diabetes (years), FBG and PPBG levels was carried out. Pearson’s coefficient (r) was reported for normally distributed variables. Among 385 PWDs, mean FBG was 146 mg/dl (±54.7), 2-hr PBG was 210 mg/dl (±82). Median score for overall adherence to diabetes self-care was 25 (IQR:21 to 29). Higher self-care efficacy was seen among 55% (n=212). Overall adherence to self-care was significantly and negatively correlated with age and glycemic measures. Self-care efficacy was mainly driven by adherence to diabetes medication. Adherence to preventative care, exercise and home monitoring of blood glucose was low. FBG was significantly and negatively correlated with glucose regulation (r=-0.16, P=0.001), diabetes medication and food regulation (r=-0.11, P=0.03), preventative care (-0.14, P=0.03) and overall adherence to treatment (-0.15, P=0.004). 2-hr PBG was significantly and negatively associated with all domains of self-care (r -0.14, P=0.04 to -0.21, P<0.0001). Elderly persons, may face difficulty with regular physical exercise, dietary recommendations and overall adherence to self-care. Continuing diabetes education is imperative to motivate PWDs and caregivers regarding importance of self-care efficacy in glycemic regulation and diabetes care.

The Role of Heuristics and Biases in the Choice of Risk Triggers for Novel Foods and GMOs in the European Union

Abstract In the European Union (EU), novel foods and Genetically Modified Organisms (GMOs) are subject to long and costly authorisation procedures and post-marketing requirements. The regulatory frameworks applicable to novel foods and GMOs come into effect based on perceived factors of risk. These “risk triggers” are characteristics of novel foods and GMOs which differentiate them from traditional foods, creating a presumption of risk. Within the EU, consumer acceptance of genetically modified foods and novel foods like insects or cultivated meat is shaped by heuristics and biases, mainly focusing on the “novelty” and “unnaturalness” of these products, resulting in a predominantly negative perception. This paper investigates the close connection between cognitive biases identified in consumer perception literature and the implementation of specific risk triggers in the regulation of novel foods and GMOs in the EU. It subsequently raises concerns about the appropriateness of these risk triggers in forming a presumption of risk for these innovative products.

Staying Out of Trouble: FDA Regulation of Orthobiologics and the Shoulder Surgeon

Food and Drug Administration (FDA) regulation of Orthobiologics can be challenging to interpret for the non-regulatory scientist. However, understanding how regulations apply to clinical use of these orthobiologic products is critical, as there are both ethical and legal ramifications to using orthobiologics in conflict with regulations. Recent FDA guidances have attempted to clarify these issues, although questions still remain regarding nuances in regulatory applications. FDA guidances, industry blogs, and relevant publications were searched for citations regarding recent orthobiologics and regulations. These sources were compiled into a current assessment of FDA regulations regarding the use of orthobiologics in the shoulder. Key to understanding these regulations is the FDA differentiation of human cellular and tissue based products (HCTPs) into 361 and 351 category products. While some controversy still exists, FDA has attempted to clarify these issues with several recent guidances. Of equal importance, FDA has ended enforcement discretion for many biologic products in June of 2021, creating a previously tolerated class of orthobiologics that now requires an Investigational New Drug (IND) application and subsequent Biologic License Application to legally market these orthobiologics. The Same Surgical Procedure Exception was further clarified in 2017 to exempt facilities from regulatory controls when specific guidelines are met. This article attempts to clarify the current thinking on FDA regulations and will allow the shoulder and elbow surgeon to stay within the current bounds of ethical and legal use of these products.

Progress and prospects of safety assessment methods of medicinal and food homologous substances

Food and medicinal substances(FAMS) with both edible and medicinal uses have a long history in China, being an important part of China's excellent traditional culture and traditional Chinese medicine(TCM). The legal management of FAMS is in the form of catalogue, which has a history of nearly 40 years. More than 100 substances have been included in the China's FAMS catalogue. According to the Regulation of Food and Medicinal Substances Catalogue, safety assessment is a basis for substances to be included in the catalogue. The safety assessment of FAMS should follow the principles and requirements of food safety risk assessment. However, FAMS is a complex mixture, and the nature and data adequacy of the assessed substance should be comprehensively considered. Different eva-luation models and methods should be selected according to the principle of case analysis. With the development of next-generation technologies such as big data, artificial intelligence, high-throughput and high-content in vitro testing, and computational toxicology and the trend of increasing edible substances with medicinal effects applying for the inclusion in the China's FAMS catalogue, the methods of risk assessment are applied in the management of FAMS, novel food products, and local characteristic food products, playing a scientific role. This paper systematically reviews the methods, challenges, and prospects of safety assessment of FAMS.

Eu(III)-functionalized metal–organic framework as a visual ratiometric fluorescence sensor for rapid discrimination and detection of multiple tetracyclines in agricultural products

The misuse of oxytetracycline (OTC), doxycycline (DOX), tetracycline (TC), and chlortetracycline (CTC) poses a serious threat to human health and it calls for rapid and visual methods. In this study, a novel ratio fluorescent sensor was constructed by simply combining Eu(III) with IRMOF-3. Spectral characterization and DFT theoretical calculations revealed different mechanism of interactions between the MOF-based sensor and different tetracyclines in detail. PCA analysis amplified these differences, enabling the simultaneous identification and differentiation of individual, binary or ternary mixtures of multiple tetracyclines. Subsequently, a rapid fluorescence sensing method (<5 min) for detecting OTC, DOX, TC, and CTC was established with low detection limits of 70, 75, 40, and 168 nM, respectively, which are all below the maximum residue limits by the European Union and the U.S. Food and Drug Administration regulations. A portable visual test strip was also conducted based smartphone with low detection limits of 1 μM, exhibiting an obvious color spectrum transition from blue to purple and finally to pink. Furthermore, the sensor was applied successful to pig feed, milk and veterinary drugs. The results showed good agreement with HPLC-MS/MS analysis.

Dietary management and access to treatment for patients with glucose deficiency syndrome type 1: an overview review with focus on the European regulatory framework.

Glut-1 deficiency Syndrome (GLUT-1 DS) is a rare disease caused by a mutation in the SLC2A1 gene that codes for the glucose transporter protein GLUT-1 DS. Currently, there is no indicated drug therapy for this condition and ketogenic diet (KD) is the most effective remedy to treat it. The objective of this study was to review the published literature that evaluated the effectiveness of KD in the dietary management of GLUT-1 DS syndrome, describing the state-of-the-art the treatment pathway for patients with GLUT-1 DS syndrome in light of the current European regulatory framework within the National Health Services. The literature search was carried out on September 10, 2023, and all studies conducted in humans diagnosed with GLUT-1 deficiency syndrome and treated with KD were included. A total of 156 scientific papers have been extracted. Applying the exclusion criteria, 38 articles have been considered eligible. In 29 out of 38 studies, the main outcome for determining the efficacy of KD was the measurement of the number of epileptic seizures, demonstrating that patients treated with KD experienced improvements with a clear reduction in the number of epileptic attacks. Currently, in the European Union, only one country provides full reimbursement by the national health system for KD. Although they are crucial for the treatment of GLUT-1 DS, according with current food regulations, KD are not evaluated on the basis of an unambiguous efficacy result, but only on the basis of safety. As a result, it is desirable to carry out clinical studies in the coming years based on the determination of efficacy in target populations, also in view of the marketing of these products on the European market.

The Limits to Food and Beverage Industry Influence over Fiscal and Regulatory Policy in Latin America.

Little is known about the political, institutional, and social contexts contributing to a decline in food and beverage industry power and influence over fiscal (soda taxes) and regulatory (sales/advertising restrictions and food labels) policy. This article addresses this issue by exploring why Mexico and Chile eventually saw such a decline in the food and beverage industry's influence whereas Brazil was not as successful. I argue that in Mexico and Chile, these outcomes are explained by shifts in presidential, congressional, and bureaucratic interests in pursuing policies that went against industry preferences. This article took a qualitative methodological approach to comparative historical research. Policymakers' interest in pursuing stronger food and beverage regulations were shaped by economic and public health concerns, new electoral contexts, epidemiological information, and normative beliefs. In Mexico, the infiltration of nutrition researchers within government facilitated this process. In contrast, Brazil's government was divided about pursuing regulatory policies, with presidents favoring partnerships with industry to implement a popular anti-hunger program; industry's power endured there with limited progress in policy reforms. Governments can eventually overcome industry power and policy influence, but it depends on a whole government commitment to reform.

Utilizing sludge from catfish farming to produce vermicompost for improving soil quality

Abstract Earthworm organic waste is processed into vermicompost, which is of varying quality depending on the substrate. In vermicomposting, earthworms can promote nitrogen mineralization and effect nitrification. A challenging-to-absorb nutrient will be converted into a nutrient that plants can easily absorb to improve nutrients in soil and increase crop production. In this study, an experimental model of organic fertilizer production from catfish pond bottom sludge was implemented. Sludge from the bottom of catfish ponds is composted with water hyacinth in aquatic ponds to produce organic fertilizer, mature fertilizer is used as a substrate for vermicomposting. The impact of vermicompost on plant growth parameters was evaluated through its use to improve nutrients in soil. Sludge, compost, vermicompost, and soil quality were also evaluated for their physical and chemical properties. Results show that the growth coefficient of earthworms is 129.3±1.15% per 30 days, and the average amount of organic fertilizer created is 126±3.51 kg per 30 days. The quality parameters of vermicompost all meet national standards for organic fertilizer quality. The moisture and total organic matter content in mature fertilizer are 31% and 21.9%, respectively. The content of nutrients N and P increased compared to input materials, the corresponding values reached 2.84% and 0.96%. The C/N ratio is 7.7, microbiological and heavy metal indicators are within the accepted limits. In the experiment using vermicompost to cultivate Brassica rapa chinensis, the yield growth rate was the highest. After 21 days of planting, the growth rate is fast and the height reaches 25.0±0.38 cm. The biochemical composition ensures safety according to food regulations for leafy vegetables. Vermicomposting is recommended as a sustainable and suitable technique for catfish pond sludge utilizing.

Lipids from the purple and white açaí (Euterpe oleracea Mart) varieties: nutritional, functional, and physicochemical properties.

The Brazilian superfruit called Açaí or Assaí has gained interested from researcher and consumers worldwide, due to its health-related properties. In this context, this pioneering study aimed to compare the physicochemical, nutritional, and thermal properties of vegetable oils obtained from two varieties of açaí (Euterpe oleracea), purple and white. Both açaí oils from white (WAO) and purple (PAO) varieties were obtained by using the conventional solid-liquid extraction, which resulted in oil yields ranging from 52 to 61%. WAO and PAO were analyzed by their edibility quality parameters given the recommendations from Codex Alimentarius; their nutritional functionality indices and their composition of fatty acids and triglycerides content were estimated. Both oils showed low levels of acidity and peroxides, <1.8 mg KOH g-1 and < 1.7 mEq kg-1, respectively, which are good indicators of their preservation status, agreeing with the food regulations. PAO and WAO showed differences among the composition of fatty acids, mainly related to the content of monounsaturated fatty acids (MUFAs), which were 62.5 and 39.5%, respectively, mainly oleic acid. Regarding the polyunsaturated fatty acids (PUFAs), the WAO showed up to 23% of linoleic acid, whereas the PAO exhibited up to 11% of it. These differences reflect on the values of the nutritional functionality indices, atherogenic (AI), thrombogenic (IT), and hypocholesterolemic/hypercholesterolemic ratio (H/H). Both PAO and WAO showed low levels of AI and TI and superior values of H/H than other oilseeds from the literature. These results indicate the nutritional properties of açaí oils regarding a potential cardioprotective effect when included in a regular dietary intake. The thermogravimetric behavior and the evaluation of oxidation status by infrared spectroscopy (FTIR) were also studied. Both açaí oils demonstrated higher thermal stability (with an onset temperature ranging from 344 to 350 °C) and low indications of oxidation status, as no chemical groups related to it were noted in the FTIR spectrum, which agrees with the determined acidity and peroxide content. Moreover, the FTIR analysis unveiled characteristic chemical groups related to fatty acids and triglycerides, agreeing with the literature reports. These findings collectively contribute to a deeper comprehension of the nutritional and functional properties between white and purple açaí oils, offering valuable insights into their potential health, food, and industrial applications.

Regulatory decentralization and food safety: evidence from China

AbstractIt is not clear, a priori, whether a centralized or decentralized institutional arrangement is better at providing public goods. This study investigates how decentralization of regulatory authority affects public good provision, focusing on food safety. Using a natural experiment that transfers food safety regulatory authority over the food processing and manufacturing sector from provincial to city‐level governments, we find a 51% decrease in the average number of food safety incidents within cities that experienced the decentralization reform. Decentralization reduces food safety incidents by rectifying information asymmetry in food safety regulations and by increasing local food safety laws and regulations. Additional analyses show that decentralization primarily improves the food safety of larger and more experienced firms, and it has not harmed the total revenue of large‐scale food processing and manufacturing firms. Our study demonstrates the importance of information available to regulatory authorities in food safety regulation and highlights the role of local information in the decentralized provision of public goods.

A Risky Business? Climate Change and Meat Reduction in Aotearoa New Zealand. A Media Framing Analysis

ABSTRACT The reduction of red meat in high-income countries is an impactful climate action and necessary to balance the projected growth of meat consumption in middle-income countries. Aotearoa New Zealand (herein Aotearoa) is a high-income country with elevated per capita greenhouse gas emissions. This research presents a media framing analysis of 58 news media stories on meat reduction as a climate action. It illuminates how arguments are constructed rhetorically and debates about meat reduction made convincing. Within Aotearoa media, a “risk” frame has been adopted for both pro meat reduction and anti-meat reduction positions. Arguments favoring reduction considered the risks of meat consumption to both human health and ecological systems. Arguments against meat reduction focused on risks to humans, relying on nutritional science to support claims. Both positions emphasized individual action and responsibility, presenting dietary “choice” as the foremost way to manage risk. In doing so, structural changes such as government policy change or food regulation were de-emphasized.

Design of point-of-care electrochemical sensor for therapeutic drug monitoring of ofloxacin in biological fluids

A disposable screen-printed sensor has been crafted specifically for therapeutic drug monitoring purposes, particularly for detecting ofloxacin in biological fluids. To enhance selectivity toward ofloxacin, a supramolecular calix [6] arene serves as the ionophore of choice. The sensor incorporates a graphene nanocomposite as an ion-to-electron transducer layer, which not only boosts potential stability but also mitigates potential drift. The developed ofloxacin sensor underwent rigorous characterization following IUPAC guidelines. The linearity range spans from 1 × 10–6 to 1 × 10–2 M, with a measured slope of 59.0 mV/decade. Impressively, it boasts a percentage recovery of 100.18 ± 1.60 and a low detection limit (LOD) of 6 × 10–7 M. Stability assessments indicate reliable performance over an extended period of 8 weeks. The versatility of this sensor extends to various applications, including the determination of ofloxacin in pharmaceutical formulations, bulk powder, and biological fluids. Notably, it has demonstrated efficacy post-bioanalysis validation, adhering to Food and Drug Administration regulations. This advancement holds promise for personalized therapeutic drug monitoring in clinical pharmacy studies and quality control laboratories, thereby optimizing patient care at the point-of-care.Graphical abstract
