Q: How Long Does Vinegar Last?
A: I receive questions from time to time about the shelf life of vinegar. The answer is "almost indefinite".
The Vinegar Institute conducted studies to find out and confirmed that vinegar's shelf life is almost indefinite. Because of its acid nature, vinegar is self-preserving and does not need refrigeration. White distilled vinegar will remain virtually unchanged over an extended period of time. And, while some changes can be observed in other types of vinegars, such as color changes or the development of a haze or sediment, this is only an aesthetic change. The product can still be used and enjoyed with confidence.

Q: BOIL ORDERS... I have some questions.
Why must I boil my water?
When a boil order has been issued to your water system that means that either recent testing has shown the presence of organisms that could cause illness (e.g. fecal or E.coli bacteria) or technical/physical problems in the water system have significantly increased the possibility of bacterial contamination.
Boil water
Boiling water is the best way to ensure that it is free of illness-causing organisms. Bring water to a rolling boil for a minimum of 3-5 minutes. When it cools, refrigerate the water in clean containers. (a pinch of salt per quart may improve the rather "flat" taste of boiled water.)
Use only boiled water for drinking, diluting fruit juices, and all other food preparation.
Disinfect dishes
Disinfect dishes and other food contact surfaces by immersion for at least one minute in clean tap water that contains one teaspoon of unscented household bleach per gallon of water.
Bathing
Water used for bathing does not generally need to be boiled. Supervision of children is necessary while bathing or using backyard pools so water is not ingested. Persons with cuts or severe rashes may wish to consult their physicians.
During a Boil Order, can I use my tap water for....
|
Drinking |
No |

Ice cubes |
No, and existing ice cubes should be thrown out. Dispose of ice cubes, do not use ice from a household automatic icemaker, and if possible disable automatic ice maker. Remake ice cubes with water that has been boiled. |

Brushing teeth |
No |
|
Baby's formula |
No |
|
Washing fruit/vegetables |
No |

Preparing Food |

Laundry |
Yes. Since there is minimal risk inlaundry other options may be considered such as using bleach in the rinse cycle or avoiding laundry until boil order has been lifted. |

Watering grass or garden |
Yes, but fruits/ vegetables must be washed using pre-boiled or bottled water before consumption |

Can I wash my hands using tap water?
It is recommended that you wash your hands using soap and either bottled water or pre-boiled water. An alcohol-based hand sanitizer may also be used.
Can my family take showers or baths using tap water?
The risk of bathing or showering in tap water is uncertain and so should be avoided, particularly by people with open woulnds or who are immunocompromised. For those people who choose to shower or bathe in the tap water, minimize the time spent in the water and be sure to keep your eyes and mouth closed. Babies and young children should not bathe or shower in tap water because they often swallow some water accidentally.
Can I wash dishes using tap water?
You may use a dishwasher if it has a sanitizing cycle. If it does not have a sanitizing cycle, or you are not sure if it does, you may hand wash dishes and utensils by following these steps:
- Wash the dishes as you normally would.
- As a final step, immerse the dishes for a least one minute in lukewarm water to which a teaspoon of bleach per gallon of water has been added.
- Allow the dishes to completely air dry.
Can I use my coffee maker, ice machine, water or soda dispenser?
None of these devices should be used if they are directly connected to your water supply. Also, filters are unacceptable for removing bacteria. Once you have been notified that the Boil Order has been lifted, these devices should be cleaned and sanitized according to the operator's manual for the device.
What if I drank water already?
There is nothing you can do about the exposure you have already received. If you become ill, contact your health provider. Follow the above recommendations about using your water until you are told the water is safe again.
What are the symptoms of water-borne illness?
Disease symptoms may include diarrhea, cramps, nausea and possible jaundice and associated headaches and fatigue. Symptoms may appear as early as a few hours to several days after infection and may last more than two weeks. These symptoms, however, are not just associated with disease-causing organisms in drinking water; they may also be caused by a number of other factors.
