SUMMARY Studies were conducted to determine the effects of competitive growth of microorganisms and development of fluorescence on inoculated poultry during refrigerated storage. Pseudomonas fluorescens rapidly outgrew Staphylococcus aureus in broth at 15°C when the initial concentration of staphylococci was about ten times as great as that of the Pseudo‐monas. On stored chicken previously chilled in water containing various levels of pseudo‐monads, S. aureus, Echerichia coli , and Streptococcus faecalis , growth of the fluorescing pseudomonads greatly surpassed that of the other organisms. Fluorescing bacteria attained large populations on chicken even when S. aureus initially outnumbered the fluorescing spoilage organisms by 100:1. Little change occurred in the populations of S. aureus recovered from inoculated poultry during storage for one week at 5°C.
