1. Will the equipment provide the time and temperature control that is necessary for safe food Is the equipment properly sized for the volume of food that will be prepared Can the equipment be sufficiently controlled so that the variation in performance will be within the tolerances required to produce a safe food Is the equipment reliable or is it prone to frequent breakdowns Is the equipment designed so that it can be cleaned and sanitized Is there a chance for product contamination with hazardous substances What product safety devices such as time and temperature integrators are used to enhance consumer safety 3 4 7 Packaging Does the method of packaging affect the multiplication of microbial pathogens and or the formation of toxins Is the packaging material resistant to damage thereby preventing the entrance of microbial contamination Is the package clearly labeled Keep Refrigerated if this is required for safety Does the package include instructions for the safe handling and preparation of the food by the consumer 11 e Are tamper evident packaging features used e Is each package legibly and accurately coded to indicate production lot e Does each package contain the proper label Almonds stored in packages and loaded on palettes at the end of their processing Each box has detailed information about the production lot to aid in a recall and an HACCP analysis of the source of the hazard 3 5 Determination of2. cleaning and when necessary sanitizing If necessary such equipment must be taken apart for thorough cleaning Cleaning is done on a pre planned regular schedule Most cleaning operations are conducted at the end of the work day or at a prescribed time before the shift begins Sanitation requires that a sanitizing compound such as chlorine be applied to the cleaned surfaces so that the level of bacteria can be reduced to an acceptable level Sanitation is done at different times for various parts of the plant The following is a recommended schedule of sanitation for the various parts of a processing plant e Plant floors every day and during mid shift e Plant walls every day before each shift e Equipment before use for every batch e Other utensils prior to use PEST CONTROL Food plants must have structures to control insects rodents birds cats and other animals Flies bees rats and mice invade the food plants in search of food Cats and other animals enter the plant in search of rats and mice All structures and equipment should be secured against them Doors windows and other openings must be secured Openings that are typically left open for ventilation should be screened Installation of air curtains fans and electrocutors at strategic locations will be extremely helpful Snap traps glue boards and bait stations must be placed around the immediate building exterior and interior walls 2 6 Processes and Controls RAW MATERIAL
