Which organisms can cause eggs to develop green or pink rot during long storage?

Certain spoilage organisms can cause eggs to develop green or pink rot when stored for long periods. These microorganisms include bacteria such as Alcaligenes, Proteus, and Pseudomonas, as well as various types of molds.1

While these organisms are capable of causing spoilage, modern market practices ensure that eggs move through distribution channels rapidly, making it rare for consumers to encounter such spoiled eggs.1
