Determinants of the decision to build up excessive food stocks in the COVID-19 crisis.

In 2020, the first COVID-19 lockdowns resulted in food panic buying and excessive food stockpiling across many countries around the world. Many governments recommend keeping emergency food stocks for three to ten days for times of potential shortages in food supply. Based on data from an online survey conducted among Swiss inhabitants, we investigated the effect of knowledge level and stockpiling behaviour according to governmental stockpiling recommendations in normal times on the decision to build up more food stocks than usual during the first lockdown in 2020. For this purpose, we applied a combination of latent class analysis and logistic regression. Latent classes were constructed based on knowledge level and stockpiling behaviour according to governmental stockpiling recommendations in normal times. Subsequently, the information on class membership was used as predictor of the decision to excessively stockpile food during the first lockdown. The variable "class membership" revealed that respondents with a low knowledge level and food stocks below governmental recommendations in normal times had a 7.6 percentage points lower probability of excessively stockpiling food during the first lockdown than respondents with a high knowledge level and recommended food stocks in normal times. Excessive stockpiling was additionally driven by the worry that certain food products would disappear from the supermarket shelves entirely or would be in short supply. Moreover, regression results revealed that respondents who reduced their shopping frequency during the first lockdown in 2020 showed a higher probability of building up more food stocks than usual. Our findings are crucial for food suppliers and policymakers to understand the drivers of panic buying and to prevent this phenomenon in future crises.

Drying-off practices on Swiss dairy farms: Status quo and adoption potential of integrating incomplete milking.

Drying-off practices to reduce milk production before dry-off are gaining attention because high milk yields at dry-off are becoming more common and increase the risk to cow health and welfare during the dry period. Incomplete milking for the last days before dry-off is one approach for reducing milk production. We conducted an online survey to determine the currently used drying-off practices on Swiss dairy farms and to identify the adoption potential of integrating incomplete milking before dry-off. In March 2021, the online survey was sent to a representative sample of 1,974 Swiss dairy farmers. A total of 518 completed questionnaires were analyzed. The mean number of dairy cows per farm was 39 (range: 11-140 cows). Thirty-five percent of cows produced considerable quantities of milk (>15 kg/d) at dry-off, and milk yield at dry-off increased with increasing annual milk yield. Abrupt dry-off was applied on 45% of the farms. The participants reported observing behavioral changes of cows such as increased vocalizations and decreased lying time associated with dry-off. Selective dry cow therapy was applied on 74% of the farms, and 44% of the participants indicated the use of antibiotics at dry-off as being "rather often," "often," or "always." Correlation analysis revealed that with increasing annual milk yields, the frequency of observed behavioral changes and antibiotic use at dry-off increased as well. Therefore, drying-off approaches that reduce milk production while supporting cow welfare are needed. We found that farmers showed an interest in testing the presented drying-off approach of incomplete milking. In addition, the farmers indicated that they would be more willing to test incomplete milking before dry-off if it became available for automated use in milking parlors or robots. Uncertainties regarding udder health appeared to be the main barrier for the adoption potential of this approach.

How did the COVID-19 pandemic influence health-related behaviour? An online survey on food choice, physical activity and changes in body weight among Swiss adults.

The COVID-19 pandemic has affected all aspects of our everyday lives. To investigate these behaviour changes, an online survey was conducted with 1'028 individuals (51% female) in Switzerland between June and July 2020. The questions referred in particular to the lockdown in spring 2020. We put specific focus on the pandemic's impact on health-related behaviour, which includes food choice, physical activity and body weight management. For instance, participants reported whether and how their consumption of different foods changed during the lockdown. As a measure of healthy food choice, we chose consumption of vegetables and salad and in contrast, sweet snacks and alcohol consumption was used as a measure for unhealthy food choice. For physical activity and body weight, participants indicated whether it decreased, increased or did not change during the lockdown as compared before. In a next step, we investigated the influence of various predictors on health-related behaviour using multinomial logistic regression models. We find that the possibility to work remotely led to healthier food choices, that is, a reported increase in vegetable consumption and decrease in sweet snack consumption, but also to more unhealthy food choices and lifestyles, that is, a reported increase in alcohol consumption as well as an increase in sweet snack consumption. For weight change, the data indicated that individuals who worked remotely were more likely to gain or lose weight than individuals working from the office. Our findings demonstrate how individuals are affected differently by the pandemic and how complex the whole picture is. Further, these results are crucial in developing health recommendations for possible future lockdowns or health crises in general.

The adoption of precision agriculture enabling technologies in Swiss outdoor vegetable production: a Delphi study.

Digital technologies are a promising means to tackle the increasing global challenges (e.g., climate change, water pollution, soil degradation) and revolutionising agricultural production. The current research used a two-stage Delphi study with 34 experts from various domains, including production, advisory and research, to identify the key drivers and barriers, the most promising technologies and possible measures to support technology adoption in Swiss outdoor vegetable production. Combining these experts' views, the method provides realistic scenarios for future development. In Round 1, open-ended questions were used to collect the experts' opinions. These were then transformed into closed-ended questions for Round 2, where controlled feedback was provided to the experts. Twenty-six experts participated in both rounds, resulting in an overall response rate that was comparably high (76%). It was found that economic factors were important drivers and barriers in technology adoption and, consequently, the experts recommended financial measures to support this adoption. The practical relevance of new technologies provided through communication and education holds further potential in terms of their promotion. These findings are valuable beyond the research field. Educators and policy makers can build on the results and optimally align their efforts to target technology adoption and contribute to more sustainable agriculture.

Cross-cultural validation of the short version of the Food Disgust Scale in ten countries.

The cross-cultural testing of scales represents an important step in the scale validation process. The present study evaluated whether the eight-item short version of the recently developed Food Disgust Scale (FDS-short) is a reliable and valid tool for measuring food disgust sensitivity in ten countries: Australia, China, England, France, Germany, Mexico, South Africa, Spain, Sweden, and the USA. In an online survey, the participants (N = 6128) answered items from the FDS-short and other scales related to (food) disgust sensitivity so as to test the construct and criterion validity of the FDS-short. Confirmatory factor analysis of the one-factor structure of the FDS-short revealed an adequate to good model fit in all the countries except for China. Multiple group analysis to test measurement invariance showed the FDS-short to be metrically invariant in all the tested countries (except for China) relative to Australia. With regard to the construct validity, significant positive correlations were observed in all the countries between the FDS-short and pathogen disgust sensitivity, sexual disgust sensitivity, moral disgust sensitivity, germ aversion, and food neophobia. Criterion validity of the FDS-short in all the tested countries was confirmed by the positive correlations between it and having a sensitive stomach, experiencing gastrointestinal complaints after eating animal-based foods (except for France and Germany), and the perceived infection risk of food-borne diseases in one's country. The direction of the correlations indicated that for each country, those with higher FDS-short scores also scored higher on all the tested constructs than those with lower FDS-short scores. Taken together, the present results indicate that the FDS-short is a reliable and valid tool for assessing food disgust sensitivity across countries.

Development and validation of the Food Disgust Picture Scale.

The present set of studies developed and tested the Food Disgust Picture Scale (FDPS). This is a tool for the assessment of food disgust sensitivity that will measure disgust and predict possible reactions. This eight-picture tool can be used in complement to or as a replacement for currently available text-based measures. In an exploratory Study 1 (N = 57), we constructed a scale consisting of eight pictures. Most of them were taken from validated picture databases. They proved powerful in the assessment of food disgust sensitivity. Study 2 built on these results and refined the scale by substituting pictures from Study 1 with freely available images displaying similar content. The basic structure of the FDPS was then replicated in a bigger sample of Swiss adults (N = 538). Correlational analyses using the eight-item Food Disgust Scale (FDS short), the revised version of the Disgust Scale (DS-R), and the food neophobia scale (FNS) supported the convergent validity of the FDPS. In Study 3 (N = 226), we used a test-retest design to demonstrate the short-term stability of the FDPS. As a result of these studies, the present work provides a short and comprehensive measure of food disgust sensitivity. This novel approach of using pictures to induce a disgust response independently of language significantly facilitates intercultural research on disgust. The FDPS will further contribute to the understanding of food-related disgust and its impact on our food choices.

Data on Swiss citizens' preferences and perceptions of agricultural policy.

We present representative survey data from 1,542 Swiss citizens. Data were collected across the three largest Swiss language regions (German, French and Italian) in autumn 2022. In the main part of the survey, we collected qualitative and quantitative data on their perception of agricultural policy goals and potential trade-offs. For this, participants were first asked to name the three most important agricultural policy goals. Next, they rated eight pre-defined agricultural policy goals for importance and how much budget they would allocate to the pursuit of each goal if they were to decide about the governmental budget or subsidies. For the goal conflicts, the eight goals were combined into 16 conflicting pairs, where participants were to decide which of the conflicting goals they preferred. Further, we collected information regarding who citizens considered as responsible for achieving agricultural policy goals. The survey was also used to collect personal information about the participating citizens including information such as gender, age, education level, place of residence or whether participant had (previous) work experience in agriculture and how they placed themselves regarding their political orientation on a left-right scale. We further collected behavioural data including diet, that is, meat consumption frequency and shopping behaviour, where we asked participants what attributes were important for them when buying food. At the end of the survey, we used existing and new scales to measure participants' perception of farmers, meat commitment and their perception regarding animal welfare and environmental protection using the Ecological Welfare Scale. For this study, ethical approval was obtained from ETH Zurich ethical commission (application EK-2022-N-174).

Dataset on digital technologies as learning content in farm manager training in Switzerland and willingness to use farm information systems.

This article describes the data from an online survey conducted at a farm management course in Switzerland. The survey was conducted in German and French between April and May 2021. It was emailed to teachers and students at agricultural education centres across Switzerland that offer a farm management program. In the first part, the survey investigated whether digital technologies were taught in agricultural training, and, more specifically, in basic training or in the farm management course. Next, it investigated teachers' and students' general perceptions of digital technologies in plant production and animal husbandry. The survey further included questions about information sources individuals use to learn more about digital technologies in agriculture. In a subsequent part, students who already owned or co-owned a farm were asked whether they use a farm management information system and were planning to use more digital technologies in the future. For this, we used three items investigating perceived ease of use, which were derived from a previous study and four items using a trans-theoretical model of adoption. Finally, all participants provided basic sociodemographic data and answered items related to environmental concern, based on an existing scale. The survey can be used and adapted to different contents, aiming to investigate perception and adoption of farm management information systems and study the course content, how individuals acquire knowledge or how they perceive digital technologies.

Food disgust sensitivity predicts disease-preventing behaviour beyond the food domain in the COVID-19 pandemic in Germany.

In the fight against the COVID-19 pandemic, personal hygiene behaviours such as proper handwashing have gained significantly more attention and interpersonal contact is performed with great care. Disgust, as a disease-avoidance mechanism, can play an important role in the promotion of hygiene behaviour. We know from previous research that pathogen disgust can be a predictor of an individual's behaviour in the pandemic. Given that the pandemic greatly affects our food and eating behaviour, the current study aims to add to the existing evidence and to complement it by investigating the role of food-specific disgust in the pandemic. For that, we conducted an online survey in Germany in April 2020, while the pandemic was spreading in Europe. A total of 519 participants completed the survey and provided information about their COVID-19-related attitudes and behaviours and about their food disgust sensitivity. The results show that food disgust sensitivity is an important predictor for an individual's feelings, shopping behaviour, and disease-preventive behaviour related to the COVID-19 pandemic. Given that the success of political measures to fight the pandemic critically depends on the population to support and follow the proposed measures, a better understanding of the factors driving individual behaviour is key. Implications for pandemic management are discussed.

A bitter taste in the mouth: The role of 6-n-propylthiouracil taster status and sex in food disgust sensitivity.

We investigated the relationship between perceived bitterness, food disgust sensitivity, and sex. Participants completed the 8-item Food Disgust Scale and a 6-n-propylthiouracil (PROP) taster test and were categorised as PROP non-tasters, medium-tasters, or supertasters. An analysis of variance of between-subject factors sex and PROP taster status was conducted with disgust sensitivity as the dependent variable. We found a significant interaction of sex and PROP taster status on disgust sensitivity and an association between disgust sensitivity and PROP taster status in males but not in females. Our study provided new evidence on sex differences in food disgust and PROP taste sensitivity.
