Quick Tips and Facts:
1. Green onions, also known as scallions, can indeed make you sick if contaminated with certain bacteria, such as Salmonella or E. coli. However, this is a rare occurrence, and proper handling and cooking greatly reduce the risk of illness.
2. Contrary to popular belief, the green part of the green onion is actually milder in flavor than the white part. The white part tends to have a stronger and more pungent taste.
3. Green onions are a great source of vitamin K, which plays a vital role in blood clotting and maintaining bone health. Just 100 grams of green onions provide approximately 207% of the recommended daily intake of vitamin K.
4. In some Asian cultures, green onions are considered to have medicinal properties. They are believed to help with digestion, improve circulation, and even offer relief from common cold symptoms.
5. The term “Welsh onion” is often used interchangeably with green onion or scallion, even though it is not actually native to Wales. The name originated from “Welsh” meaning “foreign” or “strange” and was given because the onion was seen as an uncommon and exotic plant in Britain.
Introduction: Green Onions As Potential Source Of Foodborne Illness Outbreaks
Green onions, also known as scallions or spring onions, are a popular ingredient in various cuisines around the world. However, recent studies have identified green onions as a potential source of foodborne illness outbreaks. This is due to the fact that they can harbor certain bacterial pathogens that pose a risk to human health.
Foodborne illnesses are infections caused by consuming contaminated food or beverages. They can result from the presence of bacteria, viruses, parasites, or toxins in the food. In the case of green onions, the primary bacterial pathogens of concern include Salmonella, Shigella, and E. coli O157.
These pathogens can contaminate green onions during various stages of production, including growing, harvesting, processing, and transportation. Poor hygiene practices, contaminated irrigation water, or contact with animal manure are some of the factors that can lead to the contamination of green onions with these bacterial pathogens.

Primary Bacterial Pathogens Associated With Green Onions: Salmonella, Shigella, And E. Coli O157
Among the bacterial pathogens associated with green onions, Salmonella, Shigella, and E. coli O157 are of particular concern. Salmonella is a common cause of foodborne illness worldwide and can cause symptoms such as diarrhea, fever, and abdominal cramps.
Shigella is another bacterium that can be found in contaminated green onions. It can cause an infection called shigellosis, which leads to symptoms such as diarrhea (often bloody), stomach cramps, and fever. E. coli O157 is a strain of Escherichia coli that produces a toxin called Shiga toxin, which can lead to severe illness, including bloody diarrhea and kidney failure.
Consuming green onions contaminated with these bacterial pathogens can result in foodborne illnesses, especially if the onions are consumed raw or undercooked. Proper cooking techniques are essential to reduce the risk of infection and ensure food safety.
Survey Results: 99.7% Of Green Onion Samples Free From Bacterial Pathogens Or Generic E. Coli
A survey conducted in Canada collected 591 samples of green onions from the market to determine the prevalence of bacterial pathogens. The results of the survey were encouraging, with the majority of green onions found to be free from bacterial pathogens or generic E. coli.
Out of the samples tested, an impressive 99.7% were free from any bacterial pathogens or generic E. coli. This suggests that the risk of foodborne illness associated with green onions is relatively low. However, it is important to note that 0.2% of the samples were found to be contaminated with Salmonella, which is a potentially dangerous pathogen.
These findings emphasize the importance of continued vigilance when handling and preparing green onions. While most samples were safe for consumption, it is crucial to take necessary precautions to minimize any potential health risks.
