Storage shelf life of rabbit minced meat stored for 10 days at 5 ± 0.2 °C. Meat samples were taken from rabbits. Administered lettuce juice fertilized with nitrate or WPH (groups III and IV, respectively) as compared to that of nonfertilized lettuce or lettuce-free diet (groups I and II, respectively).

All data are expressed as mean ± SE. All rabbit groups received diets explained in Table 2, and lettuce treatments were as follows: I: negative control (healthy animals); II: nonfertilized lettuce; III: nitrate-fertilized lettuce; IV: WPH-fertilized lettuce. Aerobic plate count expressed as log CFU/g meat.
