Why Raw Eggs are Refrigerated in the United States
/0 Comments/in Government Guidance, MN Food Code/by Jeff WebsterAs a certified food safety manager in Minnesota, you handle dozens of ingredients every day, but few have a more interesting story than the simple egg. A common question we hear about why you need to store eggs in the cooler in the United States, while they often sit on the counter in European homes. Understanding the answer is a fascinating lesson in microbiology and a critical component of Minnesota food safety.
It highlights the different yet effective paths countries take to protect consumers from foodborne illnesses. The core of the issue isn’t just a preference. Instead, it’s a regulated process centered on preventing the growth of bacteria, particularly Salmonella.
Why the U.S. Mandates Egg Refrigeration
In the United States, the journey of an egg from the farm to your kitchen involves a mandatory washing process. The purpose of this regulation from the USDA is to remove dirt, fecal matter, and other contaminants from the shell’s surface. While this cleaning makes the egg look pristine, it also removes a natural, invisible protective layer called the cuticle or bloom.
This is where refrigeration becomes essential. Without the cuticle, the eggshell is more porous and susceptible to bacteria entering. To counteract this vulnerability, they enforce a strict “cold chain.”
- The purpose of washing: The goal is to reduce potential surface contaminants immediately. However, this process sacrifices the egg’s natural, self-sealing barrier.
- The Role of the Cuticle: This thin coating, deposited on the egg just before it’s laid, seals the pores of the shell, preventing air and bacteria from getting inside.
The USDA Mandate: To mitigate the risk after the cuticle is washed away, federal guidelines require eggs to be refrigerated to below 45°F shortly after being laid and kept at that temperature through transport and storage.
Your Role in Upholding Minnesota Food Safety in Your Kitchen
While national regulations set the stage, your handling practices are where you can maintain safety. For a certified food safety manager in Minnesota, treating eggs with care is a daily responsibility that protects your customers and your establishment’s reputation. It’s about translating regulatory knowledge into consistent kitchen practice.
Applying these principles correctly is a non-negotiable part of professional food service.
- Receiving and Inspection: When you get an egg delivery, your first step is to verify that they’re clean, uncracked, and have been transported at the correct temperature. Reject any cartons that feel warm or show signs of damage.
- Proper Storage Technique: Always store eggs in their original carton in the main body of the refrigerator. Storing them in the refrigerator door, where the temperature fluctuates with every opening, can compromise their safety and quality.
- The Two-Hour Rule: This is a critical control point. Never leave refrigerated eggs at room temperature for over two hours. After this time, the risk of harmful bacterial growth increases significantly.
Beyond Eggs: The Principle of Temperature Control
The science behind refrigerating eggs is a perfect illustration of a broader food safety principle every certified food safety manager knows well: temperature control for safety (TCS) foods. The same diligence you apply to eggs should extend to all perishable items in your kitchen, from dairy and meat to cut melons and cooked starches. Mastering this is fundamental for anyone seeking a food safety certification MN.
Understanding how time and temperature affect various foods is the mark of a well-trained professional.
- The Temperature Danger Zone: Remember that bacteria thrive in the “danger zone” between 41°F and 135°F. Your goal is to keep TCS foods out of this range as much as possible.
- Consistent Monitoring: Regularly logging the temperatures of your coolers and freezers should be a habit. This documentation is crucial for health inspections and internal quality control.
- Knowledge is Protection: A deep understanding of which foods are TCS and how to handle them is a key part of continuing education in food safety and the most effective tool you have to prevent foodborne illness.
Mastering these food safety principles is fundamental to protecting public health and building a trusted reputation in our state. It’s the shared responsibility of every food professional to ensure the highest standards of Minnesota food safety.

It’s Here: The Final CFPM Installment On Under Cooked Proteins
/0 Comments/in Certified Food Protection Manager, MN Food Safety/by Christine DantzIn the final installment of our series on serving under cooked animal product, we will discuss the protein that is almost always ordered under cooked by CFPMs. Breakfast customers rarely order eggs well done. They are critical elements in many sauces and give custards rich textures. Looking at the Minnesota food code temperature rules, we can see that eggs cooked for hot holding must reach a temperature of 155 degrees for at least 15 seconds. How does this apply to over-easy eggs, Béarnaise sauce, and ice creams where the egg product never reaches 155 degrees?


CFPM and the Ubiquitous Under Cooked Protein- The Egg
If you work in a restaurant or institution that serves breakfast, you will receive numerous orders for eggs that are over-easy, sunny side up, or soft-boiled. These orders will leave the egg below the 145-degree temperature requirement stated in the food code for eggs prepared for immediate consumption. It is perfectly acceptable to cook and immediately serve an over-easy egg to a guest. The key is that they have to serve it immediately after cooking. Hence, you must include a warning if you serve undercooked eggs in your restaurant. “There may be a risk of foodborne illness when certain items are ordered undercooked.”
How do these rules apply to products like Hollandaise sauce, crème brulee, or ice cream? These items:
- have eggs
- have never reached 155 degrees
- are not served immediately
The Minnesota food code insists that pasteurized eggs substitute raw eggs. Many chefs argue that liquid pasteurized eggs do not work for particular items. Thanks to modern advancements in sanitation and pasteurization, you can purchase whole, raw, pasteurized shell eggs. Although the liquid form of pasteurized eggs is the most common, your product supplier should have whole, raw pasteurized eggs available.
While discussing raw eggs, let’s take a brief moment to talk about homemade mayonnaise and aioli. These are two egg-based products that have never been cooked. If you serve house-made mayonnaise:
- only use liquid pasteurized eggs
- always store it below 41 degrees.
Remember, you should never hold undercooked eggs in a warmer or a steam tray for service.
WHY MN FOOD CODE REQUIRES RAW EGGS TO BE REFRIGERATED?
/0 Comments/in food safety certification MN training sessions, MN Food Code/by Christine DantzIn every restaurant and nearly every home in the United States, raw eggs are stored under refrigeration at 40 degrees Fahrenheit or lower. According to the MN food code and food safety training courses, refrigerating raw eggs prevents Salmonella. Salmonella is a food-borne gastrointestinal illness that affects a reported 42,000 Americans each year. This number is certainly higher due to many mild cases which go unreported. Businesses that sell or cook eggs for public consumption must refrigerate them in an effort to prevent outbreaks of this type of foodborne illness.


Why The United Kingdom Does Not Refrigerate Raw Eggs
Many travelers to the United Kingdom, and many other parts of the world, often notice that people do not refrigerate raw eggs and store them at room temperature most often. This has puzzled many individuals who were taught that eggs should always be refrigerated. The answer to this question lies in a brief explanation of the differences in egg production and distribution between the United States and Great Britain.
The different philosophy of egg storage between the two countries is due to the difference in production standards. In the United States, farmers wash and sanitize eggs post-harvest. Correspondingly, Great Britain’s regulations dictate that eggs must remain dry throughout production and distribution. Rinsing eggs destroys the thin natural protective layer, known as the cuticle, which can prevent contaminants from entering the egg.
In the United Kingdom, a majority of egg producers vaccinate their egg-laying hens in an effort to prevent disease. Here in the United States, we use this process minimally.
According to an article written for www.foodsafetynews.com, these practices have “reduced the incidence of Salmonella illnesses in Britain from 14,771 reported cases in 1997 to 581 cases in 2009.” The entire foodsafeteynews.com article can be found here.
MN Food Code Approach To Serving Raw Eggs
In order to complete food manager certification in MN, knowledge of preventing food-borne illness is a must. Salmonella is a common food-borne illness that can potentially be deadly but is also easily preventable. There are a few MN food code statutes to keep in mind when dealing with raw eggs that can prevent the spread of this illness.
- Refrigerate eggs using temperatures below 40 degrees Fahrenheit,
- Throw away broken eggs to avoid contamination easily
- Clean dirty eggs before use
- When you need a large quantity, use pasteurized liquid eggs instead of raw shell eggs
