The principal spoilage mechanism for cooked, cured and processed poultry and game bird products is microbial growth. For cooked products, the heating process should kill vegetative bacterial cells and inactivate degradative enzymes. Consequently, spoilage of cooked poultry and game bird products is primarily due to post-cooking contamination by micro-organisms which can be minimised by MAP with CO₂ /N₂ mixtures and good hygiene and handling practices. A gas/product ratio of 2:1 is recommended.
Cured and processed poultry and game bird products contain relatively high levels of salt and/or other preservatives which effectively inhibit a wide range of spoilage microorganisms.
Possible food poisoning hazards are primarily due to post-cooking, curing or processing contamination can be minimised by maintenance of recommended chilled temperatures and good hygiene and handling practices. The reduced aw and/or addition of salt and/or other preservatives in most cooked, cured and processed poultry and game bird products inhibit most food poisoning bacteria.
* The Food Safety (Temperature Control) regulations 1995 states that the maximum Storage temperature for chilled perishable foods is 8°C. There will be flexibility to vary this when scientifically justified. For legal temperature storage requirements, please contact the Campden and Chorleywood Food Research Association.
