Sanitizing your Kitchen & Utensils:

• Thoroughly wash metal pans, ceramic dishes, utensils
  (including can openers) with soap and water (hot water if
  available). Rinse and then sanitize them by boiling in clean
  water or immersing them for 15 minutes in a solution of
  1 tablespoon of unscented, liquid chlorine bleach per
  gallon of drinking water.
• Thoroughly wash counter tops with soap and water (hot
  water if available). Rinse and then sanitize them by applying
  a solution of 1 tablespoon of unscented, liquid chlorine
  bleach per gallon of drinking water. Allow to air-dry.
• Discard wooden cutting boards, plastic utensils, baby
  bottle nipples, and pacifiers that may have come in contact
  with flood waters. There is no way to safely clean them.

Salvaging All-Metal Cans & Retort Pouches

Undamaged, commercially prepared food in all-metal cans
and retort pouches (for example, flexible, shelf-stable juice or
seafood pouches) can be saved if you do the following:

• Remove the labels if possible. They can harbor dirt and
  bacteria.
• Thoroughly wash the cans or retort pouches with soap and
  water (use hot water if available).
• Brush or wipe away any dirt or silt.
• Rinse the cans or retort pouches with water that is safe for
  drinking (if available). Dirt or residual soap will reduce the
  effectiveness of chlorine sanitation.
• Then sanitize them by immersion in one of the following
  ways:
  • Place in water. Allow the water to come to a boil for
    2 minutes.
    or
  • Place in a freshly made solution consisting of 1 tablespoon
    of unscented, liquid chlorine bleach per gallon of
    drinking water (or the cleanest, clearest water available)
    for 15 minutes.
•  Allow to air-dry for a minimum of 1 hour before opening
  or storing.
• Relabel the cans or retort pouches with a marker. Include
  the expiration date if available.
• Use the food in these reconditioned cans and retort pouches
  as soon as possible.
• Any concentrated baby formula in reconditioned, all-metal
  containers must be diluted with clean, drinking water.
