Sandwich Types




sandwich safety concerns
Sandwich Safety Concerns
  • Ready-to-eat sandwiches will not have a cook step or a “kill step.”
  • Making sandwiches may involve bare hand contact by the food handler.
  • Ingredients may include raw produce such as lettuce, sprouts and tomatoes which may carry disease causing organisms.
bare hand food contact
Bare Hand Food Contact
  • Eliminate use of bare hands where possible when handling ingredients.
  • Effective hand washing is essential when bare hands are used to handle ingredients.
  • Glove use is one option to avoid bare hand contact with food. What are other options?
hand washing steps
Hand Washing Steps
  • Wet hands using warm water.
  • Apply soap.
  • Work up a soapy lather.
  • Rub lathered hands together for 20 seconds.
  • With fingernail brush, work lather under fingernails.
  • Rinse well and dry with single-use towel.
single use gloves
Single-use Gloves
  • Never reuse gloves.
  • Always change gloves between handling raw foods and cooked or ready-to-eat foods.
  • When do you need to change your gloves?
  • Change gloves hourly when doing the same task.
hand washing with single use gloves
Hand washing with Single-use Gloves
  • Wash hands before and after wearing gloves.
  • Wash hands when changing to a new pair of gloves.
  • Sufficient time is always needed for effective hand washing.
avoid cross contamination
Avoid Cross Contamination
  • Improper storage of ingredients can result in contamination.
  • Store ready-to-eat ingredients separate from raw ingredients.
  • Cover ready-to-eat ingredients properly.
raw versus ready to eat
Raw Versus Ready-to-Eat
  • Use separate cutting boards for raw food and ready-to-eat ingredients. Why?
  • Use clean and sanitized equipment for each different task.
temperature control
Temperature Control
  • Keep hot foods hot and keep cold foods cold to control microorganism growth.
  • Pre-chilling of ingredients is a key to temperature control during some sandwich making.
cold holding temperature
Cold Holding Temperature
  • If you are “cold holding” a sandwich ingredient, it must be stored at 41º F or below.
hot holding temperature
Hot Holding Temperature

If you are “hot holding” a sandwich ingredient, it must be held at 140º F or above.

cooling requirements
Cooling Requirements

Cooked foods must be cooled:

  • To 70°F or lower in 2 hours.


  • From 70°F to 41°F or below in 4 more hours.
cooling requirements18
Cooling Requirements
  • Foods at room temperature must be cooled to:
    • 41°F or below within 4 hours.
  • In summary, different handling processes may require different cooling processes.
cooling methods
Cooling Methods
  • Shallow pans
  • Separate Foods
  • Rapid cooling
  • Ice Baths
  • Addition of ice
  • Other effective means:
    • Loosely cover or uncovered if protected from overhead contamination
cleaning food contact surfaces
Cleaning Food Contact Surfaces
  • Clean and sanitize slicers, choppers, and other equipment after each use, before next use.
  • Cleaning and sanitizing is required between raw animal species.
5 steps to effective cleaning
5 Steps to Effective Cleaning
  • Pre-clean
  • Wash
  • Rinse
  • Sanitize
  • Air dry
cleaning ingredient storage areas
Cleaning Ingredient Storage Areas
  • It is important to clean sandwich ingredient storage areas such as:
    • Full service display cases
    • Refrigeration areas
    • Self service display cases
cleaning packaging equipment
Cleaning Packaging Equipment
  • Properly clean and sanitize packaging equipment and packaging areas.
  • Properly store all packaging materials to protect from contamination.
storing cleaned equipment
Storing Cleaned Equipment
  • Store cleaned and sanitized equipment so surfaces are protected.
  • Avoid storing already cleaned and sanitized items where they may get recontaminated.
wiping cloths
Wiping Cloths
  • Store wiping cloths in properly mixed chemical sanitizer when not in use.
  • Store wiping cloths and sanitizer in properly labeled containers when not in use.
  • Change sanitizer in container when necessary.
sandwiches with raw produce
Sandwiches with Raw Produce
  • Fresh produce must be thoroughly washed in water to reduce contaminants before use.
  • Use a clean produce sink for this step.
raw produce washing
Raw Produce Washing
  • If chemicals are used in the washing step, the final step must be a rinse with water to remove residues as much as possible.
pre washed produce ingredients
Pre-washed Produce Ingredients
  • Pre-washed produce must be prepared and stored safely
fresh ingredients
Fresh Ingredients
  • Do not exceed the manufacturer’s use-by-date for each ingredient such as ready-to-eat deli meats.
  • Do not combine “old” sandwich items with “new” ones.
  • Some prepared sandwich items held more than 24 hours, may require date marking.
  • Properly protect sandwiches while being transported to prevent any environmental contamination.
  • Provide proper temperature control for sandwiches while in transport.
listeria concerns
Listeria Concerns
  • 95% of individuals who are infected with Listeria monocytogenes are hospitalized
  • This disease is the leading cause of death from a foodborne illness
listeria control in sandwich making
Listeria Control in Sandwich Making
  • Listeria is a microorganism that is associated with ready-to-eat sandwich ingredients.
  • Clean and sanitize to eliminate Listeria.
listeria controls
Listeria Controls
  • Effective and frequent cleaning process.
  • Cleaning “Flow”
  • Effective sanitizer use.
  • Safe product storage.
