Effect of gas stunning and modified-atmosphere packaging on the quality of meat from Spanish Manchego light lamb
Survival of biofilm cells of Cronobacter sakazakii formed on stainless steel and polyvinyl chloride (PVC) on
exposure to different atmosphere conditions was studied. Biofilms were formed on stainless steel and
PVC coupons by using three strains of C. sakazakii. Six day old biofilms on stainless steel and PVC coupons
were stored under N2 gas, CO2 gas, and air for up to 20 days. N2 and CO2 gases resulted in significant
(p < 0.05) further reductions of 1.79 and 2.47 log CFU/cm2 after 20 days of storage, respectively,
compared to air storage. N2 and CO2 gases led to less reduction of biofilm cells on PVC compared to those
on stainless steel. N2 and CO2 gases resulted in significant (p < 0.05) further reductions of 0.98 and 1.20
log CFU/cm2 after 20 days of storage, respectively, compared to air storage
