Abstract
Abstract Background During the last decades, several challenges have significantly affected the egg industry, such as the increasing consumer demand for animal welfare, the need for more sustainable food production, and the growing human health and food security issues related to egg consumption. The industry has responded by supplying a large variety of new eggs in the market. A better understanding of consumer behaviour, perceptions, and preferences for eggs is vital for industries to efficiently meet the expected, growing, and complex consumer demand. Scope and approach The focus of this review is threefold: (i) to identify the main factors that drive consumer behaviour perceptions, and preferences towards eggs; (ii) to discuss implications for industries and policy makers; and (iii) to identify research gaps to be addressed in future studies. A total of 34 consumer studies were identified, reviewed, and discussed. Key findings and conclusions Consumer preferences for eggs are mainly driven by intrinsic and extrinsic characteristics, as well as socio-cultural factors. While price is very important, especially in developing countries, production method in developed countries is a relevant sub-factor, from which consumers make inferences about the health, safety, and sensory properties of eggs. Sensory properties, like eggshell, yolk colours, and size, are also main determinants of egg purchases. Egg producers should better inform consumers about the differences between the various methods of production and the sensory properties of eggs. Finally, this review revealed the need to investigate more factors beyond intrinsic and extrinsic product characteristics as well as the lack of consumer studies in developing countries and on the growing plant-based egg trend.

Abstract Background It is estimated that on annual basis 40% of the European population is either vitamin D insufficient/deficient. A way to increase the vitamin D intake is to fortify a broader range of foods or by increasing the natural vitamin D content in food sources that already contain vitamin D. Eggs is once again considered part of a healthy varied diet and eggs contain a wide range of micro nutrients including vitamin D. Scope and approach Review of production methods to naturally enha...

We conducted a labelled discrete choice experiment (DCE) to assess consumers’ preferences and willingness to pay (WTP) for fresh hens’ eggs produced via different production systems (caged, barn, free range, or organic). We estimated purchase intentions and WTP for different possible reductions (0%, 10%, 20%, and 30%) of greenhouse gas (GHG) emissions and water use in the egg production systems. Data were collected using an online open-ended questionnaire completed by a representative sample of ...

Abstract The U.S. egg industry has been moving rapidly towards “cage-free” aviary housing as an alternative to conventional cages for hens. A choice experiment was used to evaluate the U.S. public’s willingness to pay (WTP) for egg attributes including housing system, color, size, and certifying agency. A significant difference in WTP for hen housing systems was found using video information treatments describing hen housing systems. When respondents were shown videos of egg production systems, ...

Abstract Fipronil is a highly toxic insecticide, and fipronil egg scandal greatly threaten people’s health. Herein, a precise and reliable method was developed for the determination of fipronil and three metabolites in chicken egg by GC-EI-MS. Sample pretreatment took about 20 min and baseline separation of four analytes were realized within 12 min by GC–MS. Moreover, the limits of detection were 0.2–0.5 ng g−1 and the limits of quantitation was 0.5–1 ng g−1 with relative standard deviations (RS...

Most large US food retailers and restaurants have made pledges to sell only cage‐free eggs. If the pledges are upheld, about 75% of the egg laying flock will have to be converted to cage‐free by the year 2025. However, it is an open question as to whether the market will support such a change. To address this issue, a national survey of over 2,000 US egg consumers was conducted to estimate cage‐free egg demand among consumers exposed to different types of information. We find a high degree of he...

ABSTRACT The egg industry has transitioned, or is in the process of transitioning, from conventional cages to alternative hen housing systems in response to legal changes in many states across the United States (US). However, consumers find it is increasingly difficult to understand the details behind those labels and specific attributes conveyed. There are multiple hen housing options with a wide range of costs and impacts on hens, workers, and the environment. This research furthers the unders...

There is a lack of high-quality evidence based on the gold standard of oral food challenges to determine food allergy prevalence. Nevertheless, studies using surrogate measures of food allergy, such as health service utilization and clinical history, together with allergen-specific immunoglobulin E (sIgE), provide compelling data that the prevalence of food allergy is increasing in both Western and developing countries. In Western countries, challenge-diagnosed food allergy has been reported to ...

Abstract Willingness to try (WTT) and willingness to pay (WTP) for eggs produced from insect-fed hens and the determinants of these behaviours were investigated in the UK. Data from a sample of egg consumers (N=294) was collected using an online survey. Factors influencing WTT and WTP were evaluated using a binary logistic regression and censored (Tobit) regression. Only 17% of participants were aware of insects as a potential animal feed. Most consumers were willing to try (72%) and pay (87%) f...

It costs money to improve the welfare of farm animals. For people with animals under their care, there are many factors to consider regarding changes in practice to improve welfare, and the optimal course of action is not always obvious. Decision support systems for animal welfare, such as economic cost–benefit analyses, are lacking. This review attempts to provide clarity around the costs and benefits of improving farm animal welfare, thereby enabling the people with animals under their care to...
