A study by the Organization of Consumers and Users (OCU) on 30 egg brands found that organic eggs are twice the price of eggs from soil-raised hens, despite there being no difference in quality or flavor. The study also highlighted a lack of freshness in one in four egg brands. OCU's testing did not find any significant variations in quality or flavor among floor eggs, free-range eggs, and organic eggs. The study also criticized the lack of best before date indication on egg shells in 25% of the brands. Finally, the study identified some egg brands that stood out for their best results in each category for quality and price.
