Is it Safe to Eat Raw Eggs?
Mention eating raw eggs to someone, and they will most likely think of two things: food poisoning and body building.
The fear of contracting a bout of salmonella poisoning stops many people from eating them raw.
However a great many people, all around the world, consume them regularly and safely.
Raw and undercooked eggs are safe to eat, when you practice good food hygiene. They are actually easier to digest than cooked eggs.
Eggs are packed with healthy protein, and a variety of vitamins and minerals (A, D, B2, B6, B9, B12, iron and zinc), and the important omega 3 and 6 fatty acids, making them a great food in a healthy diet.
Many foods and dressings are made with raw or undercooked eggs.
It is quite likely you have often safely eaten them raw without even realizing it!
Cooking with raw eggs
Many dishes around the world feature them in sauces, condiments, or as part of the main dish.

The risk of salmonella contamination
The most common form of egg contamination is with the bacteria Salmonella Enteritidis, which causes food poisoning (diarrhea, vomiting, abdominal cramps and fever).
Many people exposed to the bacteria will not develop symptoms, but exposure can be dangerous for immune-compromised people (pregnant, elderly, infirm).
A 2010 study of death certificates in the US discovered that there were, on average, 82 deaths per year caused by salmonella (from all food sources, not just eggs).2
An earlier study in 2002 by the US Department of Agriculture found that only 1 in 30,000 eggs produced, were contaminated with salmonella.3 That is 0.00003% of the number of eggs produced annually.
These two studies show that the risk of contracting salmonella from eggs is extremely low. You can take steps to lower that risk further.
Heat and acid kills salmonella bacteria
Cooking eggs and meat thoroughly, kills the salmonella enteriditis bacteria, as it can not survive heat-treatment.
Pasteurized (heat-treated) eggs may be available in your area, and are a good choice for those who are frail or immune-compromised.
Pasteurize your own eggs by holding the egg in 60°C or 140°F water for 4 minutes. The water is not hot enough to cook the eggs, but is hot enough to kill bacteria.
TIp: Acids, such as vinegar and lemon and lime juice, also kill bacteria.
How to handle eggs safely and avoid salmonella
By following good food-handling practices and purchasing eggs from healthy hens, you reduce the risk of contamination further.
- Wash hands thoroughly, before and after handling food.
- Purchase organic, free-range eggs - hens that have space to roam and eat a natural diet are healthier, good living conditions reduce the risk of contamination.
- Ensure the eggs are fresh, and keep them covered in a refrigerator - egg shells are porous and can absorb odors from other items in the fridge.
- Alternatively, freeze eggs outside of their shells in ice-cube trays, and then store the frozen egg-cubes in a sealed freezer bag.
- Use within 2 weeks of purchase.
- Wash eggs shells under water, just before cracking them.
- Avoid using any eggs that have a cracked shell.
- Prevent cross-contamination - as with raw meat, wash containers and surfaces that have been in contact with raw eggs before using them for other foods.
Raw eggs are as safe as salad, peanut butter and fruit
Outbreaks of salmonella poisoning, originating from salad vegetables4, sprouts5, peanuts6, and even fruit (watermelon7), have shown that safe handling of all produce is important, throughout the food production and processing line, and also by consumers.
Raw and undercooked eggs are used in so many dishes, sweets and treats that it would be a shame to not eat them.
Choose cold, fresh, free-range eggs, handle them hygienically, following good food-safely practices, and you will ensure they are safe for eating!
