“…The findings of Banaszewska et al (2020) agree with Filipiak-Florkiewicz et al (2017), who compared the quality of certified organic, nutraceutical (enriched in n-3 fatty acids) and conventional (cage-rearing system) farm eggs through a one-way analysis of variance (ANOVA), finding high levels of protein, potassium, and copper (Cu) content in the yolk of organic eggs; in addition to higher protein content in albumin.…”

“…These authors compared the eggs quality from organic and conventional farms, and the sodium (Na) and potassium (K) content, using a mean difference analysis. The findings of this research indicate a slightly better quality of eggs produced under organic farming compared to eggs in confinement; in addition to a higher Na and K content in albumen, yolk, and whole egg (Banaszewska et al, 2020).…”

“…The perception that pasture-based production is sustainable and animal-friendly was analyzed by Banaszewska et al (2020), in whose study they also included the environmental and human benefits, in addition to the improvement in egg quality. These authors compared the eggs quality from organic and conventional farms, and the sodium (Na) and potassium (K) content, using a mean difference analysis.…”

Eggs are a highly consumed animal product in Costa Rica. It is grown in different production systems and differentiation attributes, although there is little information about consumption and consumer preferences for grazing production. This study aimed to determine the effect of free-grazing on the price per kilogram of eggs paid by the consumer in Costa Rica. The results show a positive effect of 19.77% on price of eggs produced in free-grazing systems, but preference for other attributes such as nutritional fortification, egg size and brand names were also determined. Incorporating free-range technologies to replace caged poultry production can contribute to animal welfare and balance with nature, and producers can opt for differentiated prices in local markets.

“…The production of organic eggs is regulated in Europe and the United States (US) and requires that hens receive feed from organic vegetables that are not only cage-free but also have an outdoor area to move and behave as freely as they did originally (14)(15)(16). It is important to note that although there is no consensus yet, biochemical trials have assessed organic eggs as having lower concentrations of environmental contaminants and higher concentrations of micronutrients desirable for their positive health effects (17)(18)(19)(20).…”

Consumption of organic foods has increased recently, but evidence about their potential health benefits is still limited. This systematic review aims to synthesize the available scientific evidence on the association between organic egg consumption and human health. We searched for peer-reviewed articles on this subject indexed in the MEDLINE, EMBASE, Web of Science and Cochrane Library databases from the inception date to April 13, 2022. This review was based on PRISMA guideline recommendations. Three studies on organic egg consumption in humans were included. After 8 weeks of consuming organic eggs, one randomized crossover trial found that participants had higher serum concentrations of the beta-carotene lutein compared to the period without consuming organic eggs. Moreover, in a cross-sectional study with nationally representative data from Americans over the age of 50, it was found that consumption of organic eggs was associated with lower levels of the inflammatory markers C-reactive protein and cystine C compared with conventional eggs. Finally, in a cohort of children aged 0 to 2 years, no significant association was observed between consuming organic eggs and the risk of eczema. In conclusion, the evidence about the potential benefits of organic egg consumption and human health is promising but still requires further research. A human research agenda is proposed based on laboratory studies pointing out that organic eggs have a more desirable nutritional profile than conventional eggs.
