Quick Answer: What Is The Cold Chain And How Do You Maintain It?

Why is it important to maintain the cold chain?

Why Is the Cold Chain So Important.

The cold chain refers to the preservation of consistent temperatures for refrigerated vaccines from manufacture through delivery to health care facilities.

The result of failing to monitor vaccine temperatures accurately—even for short periods—may result in: Formula degradation..

How can you ensure vaccine is safe?

Every authorized or approved vaccine goes through safety testing, including: Testing and evaluation of the vaccine before it’s licensed by the Food and Drug Administration (FDA) and recommended for use by the Centers for Disease Control and Prevention (CDC)

How does cold chain work?

Cold chain logistics serves to keep the temperature for these goods at a constant throughout the transportation phase of the cycle. It involves correct packaging, proper transportation equipment, carefully chosen transportation routes, perfect timing, and visibility to ensure that what was expected is what happened.

What’s reverse cold chain explain?

“If a cold chain is what you call the transport chain that goes from a laboratory to the field – where vaccines must be kept at a certain temperature from the moment they are produced, until they are administered in order for them to work – a reverse cold chain is the process of stool samples that need to be tested …

Which vaccines should never be frozen?

Good temperature control during the storage and transport of vaccines is critical to ensure their potency and safety. Liquid formulations of aluminium-based vaccines against diphtheria, pertussis, tetanus, hepatitis B and Haemophilus influenzae type b, alone or in combination (adsorbed vaccines), should not be frozen.

How do you maintain a cold chain?

Proper temperature monitoring is key to proper cold chain management. Thermometers should be placed in a central location in the storage unit, adjacent to the vaccine. Temperatures should be read and documented twice each day, once when the office or clinic opens and once at the end of the day.

How do we maintain cold chain for storage of vaccines?

Keep vaccines in appropriate vaccine refrigeration equipment. Use a temperature monitoring device to ensure temperatures remain between +2 °C and +8 °C.

What are cold chain drugs?

It also outlines the medicines refrigeration procedure known as the ‘cold chain’, which includes the use of cold boxes or vaccine carriers to maintain the required temperature of medicines during transport from the manufacturer to user, or between healthcare departments.

What happens if a cold chain is broken?

Any break in the Cold Chain conditions – whether caused by failure to follow established procedures or faulty equipment – can result in food which is likely to spoil more rapidly, resulting in food that may be unsuitable and potentially be unsafe for consumption.

What drugs should be refrigerated?

A range of medicines need to be refrigerated. These include insulins, antibiotic liquids, injections, eye drops and some creams. These medicines must be stored between 2ºC and 8ºC. This guidance describes how you must manage medicines which need to be in the ‘cold chain’.

How often should vaccine refrigerators have the minimum maximum temperatures recorded?

All vaccine refrigerators should have a permanent data logger in place to continuously measure the refrigerator temperature at preset 5-minute intervals. The data should be downloaded at least weekly, in addition to twice-daily minimum/maximum recordings.

How does cold chain influence the fish shelf life?

Because fish is highly perishable, the shelf-life is greatly increased if it is maintained at a temperature between 0°C and 2°C. The most effective way of maintaining product temperature between 0°C and 2°C is the liberal use of ice. This is an excellent way of chilling fish without freezing it.

What are the components of the cold chain?

The main elements of a cold chain involve:Cooling systems. Bringing commodities such as food to the appropriate temperature for processing, storage, and transportation.Cold storage. … Cold transport. … Cold processing and distribution.

How can freezing damage vaccines?

Effectiveness cannot be guaranteed for vaccines unless they have been stored at the correct temperature. Freezing may cause deterioration of the vaccine and lead to hairline cracks in the ampoule, vial or pre-filled syringe which could potentially allow the contents to become contaminated.

How long can food be left out of the cold chain?

four hoursWhen you display cold food, e.g. on a buffet, you should use suitable chilled display equipment to keep it at 8°C or below. If this is not possible, you can display food out of chilled storage for up to four hours, but you can only do this once.

Do cold temperatures affect medication?

However, liquid and injectable medications can be very susceptible to temperature extremes and even a relatively short time at a very cold or warm temperature can harm the drug product. Prescription biologic medications, such as monoclonal antibodies, are the most susceptible and worrisome with temperature extremes.

What happens if vaccines get too cold?

Freeze-sensitive vaccines contain aluminum adjuvants and irreversibly lose potency when exposed to freezing temperatures. Freeze-sensitive vaccines require storage at 2 to 8°C and can lose potency even without visible signs that freezing has occurred.

What is meant by cold chain?

A cold chain is a temperature-controlled supply chain. An unbroken cold chain is an uninterrupted series of refrigerated production, storage and distribution activities, along with associated equipment and logistics, which maintain quality via a desired low-temperature range.
