Abstract
(type = abstract)
Data on the microbial food quality of fresh Ready-to-eat produces were collected in Rutgers dining services from 2001 to 2013. Total aerobic plate count, total coliforms, confirmed Bacillus cereus count were determined using standard methods. Statistical analysis was performed on foods tested more than 35 times. Statistical distributions and histograms were generated using SigmaPlot and Microsoft Excel. All data could be described using normal distributions, once data above or below the upper or lower limit detection were considered separately. The mean value of total aerobic plate count of fresh produce were ranged from 3.40 to 6.45 log CFU/g. Among all the samples, spinach, pepper and carrot had higher mean count, while apple, onion and cauliflower had the lowest mean counts. Coliforms were most commonly found in apple, broccoli, romaine lettuce and spinach, and least commonly found in pepper. The average count of total coliform count (when present) ranged from 0.60 to 3.46 log CFU/g, with carrot having highest average, while apple having the lowest average count. Bacillus cereus were most commonly detected in onion and least detected in tomato. B. cereus counts (when present) were highest on average in broccoli and lowest in pepper. Average B. Cereus counts for most produces were typically between ranged from 2 and 3 log CFU/g.
