Egg prices in the US have surged by over 100% in the past year, leading to concerns about price gouging and allegations of collusion among industry leaders. This is due to the impact of bird flu outbreaks and inflation, which have resulted in the culling of millions of chickens and increased production costs. However, trade groups and experts argue that the high prices are largely due to commodity markets and various other factors. Senator Jack Reed and Farm Action have called for an investigation into potential price manipulation, focusing on the top US egg producer, Cal-Maine Foods, which has seen significant sales growth due to the high prices.
