Abstract:
This paper is about the mathematical methods used in calculating the 12D radiation-dose for a food which has been subjected to an inoculated pack. It concerns the case in which only one partial-spoilage data point is obtained from the experiment. A simple, partly graphical procedure is described. This method is based on binomial confidence limits and furnishes an estimate that lies above the (unknown) true 12D value with probability greater than 90%. The method is applied to an inoculated pack for low-level nitrite/nitrate ham described by Anellis et al. (2).

Cleaning, Sterilization, and Disinfection
Cleaning
The cleaning process usually involves using water with detergents or enzymatic cleaner and removing foreign material from objects and surfaces, including organic material such as body fluids or inorganic material like soil. Cleaning is performed before high-level disinfection and sterilization because foreign materials on the cover of the devices interfere with process...

Methods of Sterilization I: Physical Methods
Steam sterilization uses non-toxic, low-cost moist heat in the form of saturated steam under pressure, which is fast, microbicidal, and sporicidal, and quickly warms and penetrates fabrics. Autoclaves, or steam sterilizers, expose each item to direct steam contact for a predetermined time at the necessary...
