Why Does Subway Make You Sick?

Subway is a popular fast-food chain known for its sandwiches and salads. However, for some individuals, consuming food from Subway may lead to feelings of sickness. While this experience can be frustrating and concerning, it’s essential to understand that there could be various reasons behind why Subway makes you sick. Let’s explore seven possible causes:

Food Sensitivities or Allergies

One potential cause could be an underlying food sensitivity or allergy to certain ingredients commonly found in Subway’s menu items. Ingredients like gluten, dairy, soy, or specific additives may trigger adverse reactions in susceptible individuals. Food sensitivities and allergies are indeed common concerns for many individuals, and they can potentially be the cause of adverse reactions when consuming certain ingredients.


Cross-contamination can occur when allergens come into contact with other food items during preparation or handling. If you have a severe food allergy and the staff at Subway fails to take proper precautions to prevent cross-contamination, it could result in an allergic reaction.

Food Poisoning

Another possibility is that the ingredients used in your Subway meal were contaminated with harmful bacteria or toxins, leading to food poisoning. This can happen if the ingredients are not stored properly or if proper hygiene practices are not followed during food preparation.

Improper Food Handling

If the employees at a particular Subway location do not adhere to strict hygiene standards while handling and preparing food, it increases the risk of bacterial contamination that can make you sick.

Personal Digestive Issues

Individuals with pre-existing digestive conditions such as irritable bowel syndrome (IBS) or lactose intolerance may find that consuming certain foods from Subway exacerbates their symptoms and causes discomfort.

High Sodium Content

Some people may experience feelings of sickness after consuming meals high in sodium content due to its impact on blood pressure and fluid balance within the body. Certain menu items at Subway might contain high levels of sodium, which could contribute to these symptoms.

Individual Reactions

Lastly, it’s important to consider that each person’s body may react differently to specific foods. While Subway is generally considered a safe option for many, some individuals may have an individual intolerance or sensitivity to certain ingredients used in their menu items.

How to Deal With Your Subway Sickness?

If you find yourself feeling sick while riding the subway, it’s important to know how to effectively deal with it. In this section, we will explore some practical tips and strategies to help you navigate through your subway sickness and make your commute more comfortable.

Freshness of Ingredients Matters Most

When it comes to your health and well-being, the freshness of ingredients matters most. This holds true for any meal, including those from popular fast food chains like Subway. Ensuring that the ingredients used in your food are fresh can significantly reduce the risk of getting sick. When ingredients are not fresh, they may harbor harmful bacteria or have degraded nutritional value. 

For example, wilted lettuce or spoiled deli meats can contain harmful pathogens that can lead to foodborne illnesses. By prioritizing the use of fresh ingredients, Subway and other food establishments can greatly minimize the potential health risks associated with their products. So, whether you’re dining out or preparing a meal at home, remember that freshness is key to maintaining your health and safety.

Watch Out for Cross-Contamination

To further safeguard your health when dining at Subway or any other food establishment, it’s essential to be aware of the potential risks of cross-contamination. Cross-contamination occurs when harmful bacteria or allergens from one food item are transferred to another, often through shared surfaces or utensils. 

This can happen, for instance, if a worker uses the same knife to slice a sandwich with deli meat and then uses it to cut vegetables, without properly sanitizing it in between. This can lead to the transfer of bacteria, causing illnesses such as food poisoning. 

To minimize the risk of cross-contamination, it is crucial for food establishments to have strict protocols in place, including separate cutting boards and utensils for different food items, regular handwashing, and thorough cleaning and sanitization of food preparation areas. 

Additionally, as a consumer, you can also play a role by keeping an eye out for proper hygiene practices and notifying staff if you observe any potential cross-contamination risks. By being vigilant about cross-contamination, you can help ensure the safety and well-being of yourself and others when enjoying meals at Subway or any other food establishment.

Check For Food Allergies Beforehand

To ensure your dining experience at Subway is a pleasant and safe one, it is important to check for food allergies beforehand. Food allergies can cause a range of symptoms, from mild discomfort to severe reactions that can be life-threatening. By identifying any potential allergens in the ingredients used by Subway, you can make informed choices about what to order. 

Common allergens such as peanuts, tree nuts, dairy, eggs, soy, wheat, and shellfish can be found in various menu items. Take the time to review the allergen information provided by Subway or ask a staff member for assistance. By doing so, you can avoid consuming foods that may trigger an allergic reaction and enjoy your meal without any worries or discomfort.

Be Cautious With Raw Veggies

When dining at Subway or any other establishment, it is important to exercise caution when consuming raw vegetables. While raw veggies are often considered a healthy choice, they can sometimes harbor harmful bacteria that can cause foodborne illnesses. This is particularly true if the vegetables have not been properly washed or have come into contact with contaminated surfaces. 

To minimize the risk of getting sick, it is advisable to opt for cooked vegetables or request that your raw vegetables be thoroughly washed before being added to your sandwich or salad. Additionally, be mindful of any cross-contamination that may occur, such as using utensils or cutting boards that have been in contact with raw meat. By taking these precautions, you can enjoy your Subway meal without worrying about experiencing any adverse effects.

Consider Trying a Different Location

If you find that eating at Subway consistently makes you sick, it may be worth considering trying a different location. While it is possible that your symptoms could be due to other factors unrelated to the restaurant itself, such as food allergies or intolerances, it is also possible that there may be specific issues at the Subway you frequent. 

Different locations can have variations in food handling practices, cleanliness, and overall hygiene, which can affect the safety of the food served. By trying a different location, you can assess whether your symptoms persist or improve, helping you determine if it is the specific Subway you have been visiting that may be contributing to your discomfort. 

Remember to communicate any dietary concerns or specific requests to the staff to ensure your food is prepared safely and meets your needs.

Final Words

In conclusion, if you often find yourself feeling sick after eating at Subway, it may be due to a variety of factors such as cross-contamination or food handling practices. It is important to pay attention to the ingredients and preparation methods used in your Subway sandwich to avoid potential foodborne illnesses. Additionally, be sure to report any food safety concerns to the restaurant staff or proper authorities. By being aware of these potential issues and taking necessary precautions, you can continue to enjoy Subway sandwiches without feeling sick. Remember, your health and well-being should always be a top priority when it comes to food consumption.
