Effect of Oxygen Tension on the Spoilage Microflora of Irradiated and Non‐irradiated Haddock (Melanogrammus aeglefinus) Fillets

Summary. The spoilage microflora of irradiated and non-irradiated air packed or vacuum packed haddock fillets was identified after storage of the fillets at 35°F. With the non-irradiated fillets, both air packed and vacuum packed, the spoilage flora was predominantly pseudomonads. With the irradiated fillets, the spoilage flora of the air packed samples was chiefly achromobacter; that of the vacuum packed samples was chiefly lactobacilli (or possibly Microbacterium thermosphactum).
