Summary

THE USDA REQUIRES THAT CHILI PORTIONS SHOULD BE COOLED FROM 323 TO 277 K (50 TO 4 DEG C) WITHIN 2 HRS AFTER COOKING. MODELLING OF CONTAMINATION WHEN THESE STANDARDS ARE NOT MET ; CHILI PORTIONS WERE EXPERIMENTALLY CONTAMINATED BY CL. PERFRINGENS THEN INCUBATED AT VARIOUS TEMPERATURES ; THE SAMPLES WERE THEN HEATED TO 348K (75 DEG C) FOR 20 MIN THEN MAINTAINED AT DIFFERENT TEMPERATURES FOR 6 HRS. NO GROWTH IS DETECTED IN CHILI MAINTAINED AT 303 K (30 DEG C) FOR 6 HRS. GROWTH IS OBSERVED ON SAMPLES MAINTAINED AT 305 K (32 DEG C) FOR 6 HRS AND 311 AND 323 K (38 AND 50 DEG C) FOR 2 HRS.
