A Product Manufacturing Audit Describes
-Any observed deviation from prescribed manufacturing instructions -Any potential situation for deviation -Lack of effectiveness or relevance of any step
Reasons for Conducting a Product Manufacturing Audit
-Assurance that actual practices reflect required procedures -Uncovering deviations, so they may be corrected -Conforming consistency
Organism Perpetuation
-Bacterial & some yeasts multiply by binary fission -Mother cell increases in size and divides into 2 daughter cells -Most yeast multiply by budding -Generation time average 30 minutes for bacteria -Lag phase: Dormant / slow growth -Log phase: Rapid growth (Temperature dependent) -Molds reproduce by spores, increase size by fungal hyphae (long, branching threadlike tubes, multicellular filaments) -Viruses replicate inside host cells -Parasites do not proliferate in foods, usually require more than one host for life cycle
Three Categories of Microorganisms
-Beneficial -Pathogenic (Bad, Get rid of or control) -Spoilage (Fine, cause little to no harm)
Cause & Effect Diagram
-Causes are arranged according to level of importance or detail -Interrelationship Diagrams -Depicts relationships and hierarchy of events -Causes typically arranged into 4 common categories: ---Manpower, methods, materials, & machinery (for manufacturing) ---Equipment, policies, procedures, and people (for administration and planning)
Classifications of Recalls
-Class I : Products which could cause serious injury or death, such as not labeling an allergen -Class II : Products which might cause serious injury or temporary illness, such as microbial contamination or mislabeling -Class III : Products which are unlikely to cause injury or illness, but that violate FDA regulations, such as faulty closure/sealing of a product or missing a batch number
Major Functions of the Quality Assurance Department
-Compliance with specifications: Legal, industry, company internal, shelf-life testing, customer specifications -Test procedures: Testing raw materials, in process and finished product -Sampling procedures and schedules: maximize the probability of detecting while maximizing workload -Record keeping and reporting -Troubleshooting -Special problems: customer complaints, production issues, employee training -Food plant sanitary practices -Establishes criteria for acceptable food plant -Federal regulations 21 CFR 110 - current good manufacturing practices
Observation Classes
-Critical: Any condition of actual product or container adulteration or condition in which adulteration is imminent or inevitable such as rust, peeling paint, mold, oils, dirt, lubricants, condensation, or use of unapproved chemicals. Stop production and fix immediately -Major: Any condition or practice that is a source of potential product or container adulteration such as eating, smoking, exposed light bulbs, inadequate pest control, inadequate employee hygiene, or unprotected openings to the outside. Fix as soon as possible -Minor: Any other observation from GMP's such as poor housekeeping, log/paperwork left too close to the line, foreign material on exterior of seamers, or inadequate ground maintenance. Not imminent, address when seen
Best By Date Label
-Date of ideal quality, best if consumed by -Mark of ID, batch, code, or lot number must be on the food so it can be traced -Same code = same quality -Date label must list Sell by, Use by, OR Best by date, manufactures choice as to which
Use By Date Label
-Date to be consumed OR discarded -Date label must list Sell by, Use by, OR Best by date, manufactures choice as to which
Sell By Date Label
-Date to be sold OR frozen -Still usable after date, but not manufacturer quality -Typically 1/3rd of products shelf life -Date label must list Sell by, Use by, OR Best by date, manufactures choice as to which
Quality Evaluation
-Describing or appraising the worth of a product -Means taking measurements to evaluate : ---Performance of incoming (raw) materials ---Products in process ---Finished products
Other Audits

Legal Standards of Quality
-Federal, State, Municipal -Mandatory: set up through law or regulation
Viruses Consist of
-Genetic material (RNA/ DNA) -Protein coat (capsid) -Envelope of lipids (sometimes, helps avoid immune system) -Glycoprotein (protein containing oligosaccharide chain) on surface to help identify and bind to receptor sites on host cell membrane
Product Manufacturing Audit
-Helps verify manufacturing is carried out in a suitable environment, under acceptable manufacturing conditions, and under sanitary conditions -In accordance with manufacturing documents: ---Documented work instructions ---Suitable environment ---Samples for criteria for workmanship ---Compliance with standards -Quality product dependent on quality of raw materials ---Control of purchasing ingredients ---Properly identifying ---Tracing raw materials
Viruses are Classified by
-Host group infected (animals, plants, bacteria, fungi) -Type of disease caused -Type of nucleic acid present -Structure of the protein coat -If the virus has an envelope or is naked
A TQM Mission should state:

Food Contamination Sources
-Humans: Largest contamination source besides from food itself -Equipment: Contamination occurs during use as well as idle time -Air and Water: Airborne microorganisms, water used to clean and/or as an ingredient -Sewage: From humans, in fields, entering potable water lines -Insects, Rodents, and Birds: Flies and roaches transfer filth from contaminated areas to food through their waste and body parts
Hazard Analysis Critical Control Points (HACCP) Audit
-Internationally recognized as means of assuring food safety from harvest to consumption -Verified that plan complies with the 7 principals of HACCP: Analyze hazards, determine critical control points, establish limits for critical control points, establish monitoring procedures for critical control points, establish corrective actions, establish verification procedures -Detailed observation to ensure hazards have been identified and are effectively controlled and limits are validated or proven effective
Control of Bacterial Growth in Food
-Intrinsic: Inherent to the food itself such as pH, oxidation reduction, water activity, nutrient content, naturally occurring preservatives and antimicrobials, and natural barriers such as shells and peels -Extrinsic: Controlled and modified factors such as temperature of storage, relative humidity of environment, presence and contamination of gases, and presence and activities of other microorganisms -Combined: Hurdle concept meaning to combine multiple preservation methods
X-Bar and R Chart
-Most commonly used of control charts -Ideal for improving product quality and process control - Help reduce scrap/rework -Used for control of variables expressed in discrete number such as inches, pounds, pH, percent solids, or temperature *X-Bar -Average value of several measurements *R Chart -Range of each subgroup of data -Subtract maximum and minimum values from subgroup
Audit Worksheets Include
-Observation -Classification -Type (i.e. ingredient handling, equipment) -Area of program
