packaged foods.
Know what particular group of bacteria presents
the greatest risk in vacuum-packaged foods and
why.
Understand how the food safety hazards are
controlled.
Explain the reason retailers use a shelf life for
vacuum-packaged foods of no longer than 14 days
while USDA manufacturers often use 30-45 days.
Define back flushing. Give an example when ‘backflushing’ would be used.
Know the labeling requirements for retail vacuumpackaged foods.
What is
Reduced Oxygen Packaging?
Food in a package with
less oxygen than
normal
Reduced Oxygen Packaging
(ROP)
Vacuum packaging
Modified Atmosphere Packaging
Controlled Atmosphere Packaging
Others: Cook Chill or Sous Vide
Advantages of ROP
• Extend shelf life
• Slows the growth
of spoilage
organisms
• Prevent color
changes
• Prevent shrinkage
and moisture loss
What’s the Hazard?
Biological Hazards
• Pathogenic bacteria
• Bacteria that grow without oxygen
 Clostridium
 Listeria
• Spoilage microbes will not grow
• Less competition for other bacteria
Bacteria of Concern
Bacteria that grow in an environment
without oxygen
• Clostridium botulinum
• Produces a toxin that is not eliminated by
heat
• Listeria monocytogenes
• Grows at temperatures down to 32°F
• A concern in ready-to-eat foods as a result
of cross contamination
Primary Controls
• Temperature
• Types of Food Package
• Shelf Life
• Sanitation
Temperature
• Keep cold at 41°F
or less
• Minimize time out
of refrigeration
during
processing
Types of Food Packaged
Retail Food Code regulations limit the types
of food that can be vacuum packaged to:
• Raw meat or poultry (beef, pork, chicken)
• Hard cheese (colby, cheddar, swiss)
• Cured meats (sausage, ham, smoked
turkey)
• Food with a low pH (below 4.6) or low
water activity level (below .91)
• Fish ONLY if frozen before, during and
after packaging
Shelf Life
• Limit the shelf life to 14 days from day of
packaging
• Increase in shelf life increases the risk of
Listeria growth
Developing SSOP’s
Written Procedures
• Detailed procedures for cleaning and
sanitizing.
• A checklist of equipment to be cleaned and
the frequency to be cleaned.
• Steps for the tear-down and re-assembly of
equipment.
• Procedures and schedule for cleaning nonfood contact surfaces and facilities.
• Instructions for use of sanitation chemicals.

Storage: Foods &
Packaging Materials
• Keep potentially
hazardous food at
41°F or less.
• Store food to
prevent cross
contamination .
• Store packaging
materials in a
sanitary manner.
Assembly & Packaging
• Limit time out of
refrigeration.
• Re-chill to 41°F or
less.
• At retail, only
certain foods can be
vacuum packaged.
Packaging
• When packaging
ready-to-eat
foods, limit bare
hand contact.
• Utensils, tissues
or gloves must be
used.
Packaging
• Use the vacuum
packaging machine
according to
manufacturers
instructions.
If using a gas
displacement, be sure
equipment is used
safely and effectively.
Packaging
• Designated area for
ROP
• Separate raw from
ready-to-eat
• Physical barrier
• Timing of operations
• Check the packages
for:
• Tight seal
• Tight vacuum
Packaging Materials
• Plastic films must be approved for ROP
food packaging
• Different types of films can provide
barriers to water, oxygen, flavors,
odors
• Other properties: toughness,
brittleness, impact resistance
Labeling
• Basic labeling
requirements
• Statement to ‘Keep
Refrigerated or
Frozen’
• Instructions to
discard if not used
within 14 days of
packaging
Finished Product Storage
• ROP packaged food must be stored at
41°F or less
• Monitor and record the temperature in
all storage units
• Check products daily for faulty seals,
puffy packages
• Outdated products must be discarded

6. SSOPs
HACCP
Key Points for a ROP HACCP plan:
•Cold hold at 41°F or less
•Frequency of monitoring temps
•ROP food that has been temperature
abused must be discarded
•Maintain records – temperature logs
•Calibrate thermometers
•Written SSOPs
Training
• Develop a Training Program for
employees responsible for the ROP
operation.
• Items to be included:
•
•
•
•
Concepts required for a safe operation
Equipment and facilities
Direct hand contact w/ RTE food
