Have you ever wondered why chicken seems to last longer when it’s sitting on the shelves at the store compared to when you bring it home? 🐔🤔 It can be frustrating to buy chicken only to find that it needs to be used within a few days before it goes bad. But fear not, there are scientific reasons behind this phenomenon that can help you understand how to properly store and use chicken to ensure it stays fresh for as long as possible.
**The Science Behind Chicken Spoilage**
Chicken, like all perishable foods, is susceptible to bacterial growth and spoilage. When chicken is processed and packaged for delivery to stores, it undergoes certain treatments and packaging techniques to help extend its shelf life. These include:
1. **Modified Atmosphere Packaging (MAP)**: Many stores use MAP to package chicken, which involves adjusting the atmosphere inside the packaging to slow down the growth of bacteria. This can help extend the shelf life of chicken while it’s in the store.
2. **Refrigeration**: Chicken is typically stored at the correct temperature in the store’s refrigerated section, which helps slow down bacterial growth and keeps the chicken fresh for longer periods.
3. **Preservatives**: Some chicken products may contain preservatives to help extend their shelf life. These preservatives can inhibit the growth of bacteria and help prevent spoilage.
4. **Handling and Storage**: Proper handling and storage practices during packaging and delivery also play a role in the shelf life of chicken. By following food safety protocols, manufacturers and stores can ensure that chicken stays fresh until it reaches the consumer.
**Why Chicken Spoils Faster at Home**
Once you bring chicken home from the store, it’s up to you to continue the proper storage and handling practices to keep it fresh for as long as possible. There are several factors that can contribute to chicken spoiling faster at home, including:
1. **Temperature Fluctuations**: If chicken is not stored at the proper temperature (below 40°F), bacteria can grow rapidly, leading to spoilage. Make sure to store chicken in the coldest part of your refrigerator and use a thermometer to monitor the temperature.
2. **Cross-Contamination**: Improper handling of raw chicken can lead to cross-contamination with other foods, increasing the risk of bacterial growth. Always store chicken on the bottom shelf of the refrigerator to prevent drips from contaminating other foods.
3. **Packaging**: The packaging that chicken comes in from the store may not be the most effective for long-term storage. Consider repackaging chicken in airtight containers or freezer-safe bags to help prolong its shelf life.
4. **Natural Spoilage**: Even with proper handling and storage, chicken will eventually spoil due to natural processes. It’s important to use chicken within a few days of purchase to ensure its freshness and safety for consumption.
**Tips for Storing Chicken at Home**
To maximize the shelf life of chicken and keep it safe for consumption, follow these tips for storing chicken at home:
1. **Refrigeration**: Store raw chicken in the coldest part of your refrigerator at a temperature of 40°F or below. Cooked chicken should be stored in the refrigerator within two hours of cooking.
2. **Separation**: Keep raw chicken separate from other foods in the refrigerator to prevent cross-contamination. Use airtight containers or plastic bags to store chicken safely.
3. **Freezing**: If you won’t be using chicken within a few days, consider freezing it for longer storage. Make sure to label and date the packaging to keep track of how long it has been frozen.
4. **Thawing**: When thawing frozen chicken, do so in the refrigerator or using the cold water method to prevent bacterial growth. Never thaw chicken at room temperature.
5. **Use-By Dates**: Pay attention to use-by dates on packaged chicken and use the chicken within that timeframe to ensure its freshness and safety.
By understanding the science behind chicken spoilage and following proper storage and handling practices, you can enjoy fresh and safe chicken for longer periods of time. Remember to always use caution when handling raw chicken to prevent foodborne illness and enjoy delicious meals without the worry of spoilage.
Next time you buy chicken from the store, you’ll have the knowledge to keep it fresh and safe until you’re ready to cook it. 🍗🛒 #ChickenStorageTips
Food spoils due to the action of bacteria and mold growing on the food and producing byproducts. Those organisms are present from the moment the animal is slaughtered but are kept from growing out of control by how the meat is stored.
The growth of those contaminants tends to be exponential, which means they are relatively low population for a while before reaching a critical point where they explode in population. We don’t mind or even notice the low population of bacteria and mold but when they massively increase the food is considered spoiled.
For chicken the bird was likely slaughtered about 3-5 days before it reaches the consumer. At that point it can only last a few more days in refrigeration before it might become dangerous.
Chicken doesn’t stay fresh long, but, the farming and distribution process is down to a precise science. It gets to the shelf so fast, so that much of the “shelf” life ends up in your fridge.
If there was a major disruption to distribution channels, grocery would run out of chicken immediately.
Very quickly getting the chicken from farm to table. Sometimes replacing the atmosphere in the packaging with other gases.
That fresh chicken actually only took a few days to arrive in your kitchen.
It’s refrigerated during all transport; the longer away from processing centres you live, the shorter the use before date on the packaging will actually be on the day it gets to the stores.
Apart from that thawed meet is frequently sold as well. That’s obviously not going bad because it gets flash frozen and only thawed in the shop right before putting it out for sale. And then again it’ll only last a few days.
But really, actual fresh chicken gets to your store/kitchen within 3 days of slaughter usually.
They don’t sit around in some ware house.
It gets slaughtered and processed, packaged and then is put on a truck to a distribution center. There it is unloaded, and put on the truck doing a delivery to your local store.
Thus 3 days being common with over night transport to and from a distribution centre.
In addition to other comments, the chicken will almost certainly heat up between you removing it from the refrigerated store shelf and putting into your fridge at home, allowing a period of warmth where bacteria can grow exponentially.
Refrigerated grocery store meat doesn’t stay at refrigerated temps from when you put it in your car to when it goes in your fridge. You can mitigate this by buying meat last. I’ve got a 20 minute drive from the grocery store to my house, so I generally try to put a couple frozen items in with the meat.
The temperature is strictly controlled throughout the process of packaging, delivery, sitting in the store. It’s kept cold enough to not allow growth of harmful microorganisms in that time. The “best before” date is valid when it is stored under specific conditions, it certainly allows for some variation in temp for a brief period of time (e.g. till it gets from the fridge truck to the store fridge).
But once out of the store fridge, it is transported to yours in less than ideal conditions temperature-wise. It can go bad even before you get home, if your car is hot enough and the trip home takes a certain time.
There is a period of time between when the chicken is slaughtered and processed and it goes bad. It’s not a huge window (7-8 days or so) and perhaps half of that is between the time it’s processed, sent to distribution warehouses, and ends up on the grocery store cooler. Then it sells through in a couple days, and can last a few more in your fridge before it goes bad. Fresh meats are blast cooled to get them to low temperatures as quickly as possible after processing and kept at lower temps in transport and on grocery coolers than typical home fridge, which extends the life a little.
Ask the checker to wrap it up in it’s own bag. Get it refrigerated quickly. Turn down (colder) your refrigerator. Keep it wrapped up. Do all this and you might get an extra day. Really, you should just freeze it (wrapped). You can thaw it in a few hours anytime. Still tastes good! Mmmm… 🍗🍗🍗
Any non-frozen raw chicken I buy comes with a best-before date… I just reference that regardless of how many days it’s been in my fridge vs the store’s. Yes, the period of transportation from store to home can make a difference. But also the chicken itself has heat capacity. It doesn’t instantly go from cold to room temperature just because you took it out of the fridge.
But agreed with others here, good practice to minimize the time it spends out of refrigeration. Pick it up last in the store. If you are buying any frozen food at the same time, bag the chicken together with the frozen food. When you get home it’s your first priority into the fridge.
Conversely, if I’m walking home from the grocery store when it’s “fridge temperature” outside or cooler, (I use a folding cart), I’ll put the raw meat package in a part of the cart where it’s in contact with the cold air, since that will keep it colder than being in contact with anything warmer in the cart.
The rot process starts as soon as the animal is killed. No longer do microbe fighting is halted and bacteria starts to double every 4 hours. If they happen to refrigerate it to the recommended temp (some slaughterhouses have been cited for too warm storage) then it can slow the bacterial growth by a few days only. You eat more rotted meat than you think as it doesn’t always make you sick.
Because it spent most of its “freshness window” going through packaging, delivery, and sitting on the shelf. It would still go bad in a few days sitting in the grocery store.
