Food Safety
Food Safety and Food Quality
• Food Safety: making a food safe to eat;
free of disease causing agents
• Food Quality: making a food desirable to
eat; good taste, color, and texture
Unacceptable Foods
Poor Quality
bad color
wrong texture
smells bad
Unsafe
too many bacteria
toxic chemicals
foreign objects
What are the Hazards
in our Food?
• Biological: bacteria, viruses, parasites
• Chemical: sanitizers, pesticides, antibiotics
• Physical: bone, rocks, metal
How Do Foods Become
Contaminated?
Controlling the Hazards
• Time and Temperature
• Separation
Biological Hazards
“Biological” means “living”
Biological hazards in foods include:
• Bacteria: Salmonella in chicken and eggs,
E. coli in beef, Shigella in water
• Viruses: Hepatitis in water
• Parasites: Cryptosporidium and
Cyclospora in water and produce
Examples of
Biological Hazards
In Meat and Poultry:
• Salmonella bacteria (poultry and eggs)
• E. coli bacteria (beef and ground beef)
• Trichinella spiralis parasite (pork)
Examples of
Biological Hazards
On Fruits and Vegetables:
• Salmonella bacteria (bean sprouts)
• E. coli bacteria (apple juice)
• Cyclospora parasite (raspberries)
• Hepatitis A virus (strawberries)
Examples of
Biological Hazards
Control of
Biological Hazards
Hazards are controlled by:
• Controlling and monitoring storage and
processing temperature
• Preventing cross-contamination
• Following the cleaning and sanitation
program
Control Using Temperature
Cooking helps to kill microbes
• >165oF for poultry and eggs
• >155oF for ground beef
• >160oF for pork
Holding at low temperatures (<40oF)
prevents microbes from growing
Cooling from 140o-40oF quickly helps
prevent microbes from growing
Chemical Hazards
• Chemical hazard: a toxic substance that is produced
naturally, is added intentionally or non-intentionally
• Naturally-occurring: toxic substances produced by
other living organisms
• Added intentionally: nitrates in meat, pesticide
residues in feed
• Added non-intentionally: any unwanted substance
(cleaning agents)
• Unidentified / wrong ingredient (colors)
Examples of
Chemical Hazards
In Meat and Poultry
• Nitrate agents (red meat)
• Aflatoxins, pesticides (feed)
• Growth hormones (livestock)
• Growth promoting drugs (poultry)
• Cleaners, sanitizing agents
(meat and poultry)
Examples of
Chemical Hazards
Control of
Chemical Hazards
• Approved and legal chemicals
(cleaners, sanitizers, hormones, pesticides)
• Use a safe level
• Letters of guarantee and vendor certification
• Proper procedures and rinsing
(cleaners and sanitizers)
• Storage of feed (aflatoxin)
• Storage and labeling for ingredients
and raw materials
Physical Hazards
Physical hazard: a hard foreign object that
can cause illness or injury
• Inherent to the food or ingredient
• Contaminant during processing
Examples of
Physical Hazards
In the food or ingredients
• Bone fragments (ground beef)
• Feathers from animal carcass (turkey)
Contamination during processing
• Stones, rocks, dirt in vegetables
• Metal from processing equipment
(ground beef)
• Jewelry, fingernails (food handler)
Control of
Physical Hazards
Separate and remove physical objects
• Filter or sieve (meat grinder)
• Water bath (vegetables)
• Metal detector (all foods)
• Good employee practices (jewelry)
• Good sanitation and
quality control programs
Good Manufacturing Practices
GMPs are minimum sanitary and processing
requirements necessary to ensure the
production of wholesome food.
Prescribed requirements for
• personnel
• building and facilities
• equipment and utensils
• production and process controls
GMPs: Personnel
• Knowing how and when to wash hands
• Understanding the importance of clean
uniforms
• Proper use of hair and beard nets
• Policy on jewelry
• Policy on chewing tobacco, smoking,
and eating
GMPs: Building and Facilities
• Handwashing stations
• Storage of ingredients
(refrigerated and on pallets)
• Separation of raw ingredients from
processed foods
• Pest management program
GMPs: Equipment and Utensils
• Easily cleaned and sanitized
• Easily maintained
• Meet food grade standards
GMPs: Production and Process
Controls
•
•
•
•
Time/temperature control charts
Records on food ingredients
Lot identification and coding
Product weight controls

Standard Operating Procedures
• Standard Operating Procedures (SOPs) are
established or prescribed methods to be
followed routinely for the performance of
designated operations or in designated
situations.
Standard Operating Procedures
SOPs relate to specific tasks and should address
the following:
• the purpose and frequency of doing a task
• who will do the task
• a description of the procedure to be performed
that includes all the steps involved
• the corrective actions to be taken if the task is
performed incorrectly
Standard Operating Procedures
Examples
Of
SOPs
Sanitation SOPs
• Sanitation Standard Operating Procedures
(SSOPs) are prescribed methods specifically
for cleaning and sanitizing.
Sanitation SOPs

SOPs
Cleaning and Sanitizing
Cleaning and sanitation programs are keys to
successful GMPs and SSOPs.
Cleaning
Cleaning is the chemical or physical process of
removing dirt or soil from surfaces.
Cleaning removes 90-99% of the bacteria, but
thousands of bacteria may still be present.
Sanitizing
• Sanitizing is the process that results in
reduction/destruction of microbes.
• Different sanitizers will be used for different
food products. Chlorine, iodophors, and
quaternary ammonia compounds are the
most common sanitizers used.
Sanitation Programs

Food Safety and HACCP
• Hazard Analysis and Critical Control Point
• The purpose of HACCP is to help ensure the
production of safe food
• The goal of HACCP is to prevent and/or minimize
risks associated with biological, chemical, and
physical hazards... to acceptable levels
• It is based on PREVENTION rather than detection
of hazards
History of HACCP
• Pioneered in the 1960’s
• First used for the space program Pillsbury and NASA
• Adopted by many food processors and
the U.S. government
Uses of HACCP?
A “farm-to-the-fork approach”
•
•
•
•
On-farm agriculture
Transportation
Food preparation & handling
Food processing


Meat and poultry regulations
Seafood regulations
• Food service
• Consumer handling & use
HACCP Regulations
• USDA - HACCP regulations for meat
and poultry slaughter and processing:
“Pathogen Reduction Act”
• FDA - HACCP regulations for
inspection of seafood products
• FDA requirements for fruit juice that is
not heat-processed
Steps of HACCP
1. Organize a HACCP team
2. Describe the product, ingredients, and the
process
3. Develop a HACCP flow diagram for
each product
4. Perform the 7 principles of HACCP
5. Train employees how to implement
HACCP properly
HACCP Principles
1. Identify hazards
2. Determine Critical Control Points (CCPs)
3. Determine safety limits for CCPs
4. Monitor CCPs
5. Corrective action
6. Record data
7. Verify that the system is working
The Heart of HACCP
Monitoring CCPs:
• Time/Temperature devices

Thermometers
• Separation devices
 filters, screens
The Heart of HACCP
Record Keeping:
• Who records the data?
• How often?
• What do you do if the data is not
what it should be?
• Who checks the data?

GMP’s
Sanitation
What is the role of GMPs?
GMPs are programs required by law for
procedures related to:
•
•
•
•
personnel
building and facilities
equipment and utensils
production and process controls
What is the role of Sanitation?
• A good sanitation program will maintain a clean
and sanitary environment for all areas of food
production from receiving to processing, to
storage and transportation.
• Do you know what your responsibility is?
What is the role of HACCP?
• HACCP is the program that is used in the
food industry for FOOD SAFETY, not food
quality.
• HACCP cannot work if GMPs and good
sanitation programs are not already in place.
The key element is training
• GMPs, Sanitation, and HACCP programs
cannot work if people are not properly trained
to do the job.
