Where Wallemia Grows in the USA

In the United States, Wallemia, a type of fungi, can be found in various environments. These environments typically have a high concentration of salt, sugar, or other solutes. Consequently, Wallemia often thrives in areas where food is processed or stored, including bakeries, candy factories, and households. It can also be found in agricultural settings, especially in areas with stored grains.

Specific Locations and Environments

• Indoor Environments: As Wallemia releases spores into the air, these can be present in dust in homes, schools, and offices.
• Food Facilities: It commonly grows in facilities where food, especially sweet or salty food, is produced or stored.
• Agricultural Areas: Farm settings, particularly granaries and places where hay is stored, are favorable breeding grounds for this fungi.

Though not limited to these areas, these are common environments within the USA where one can find Wallemia. The presence of this allergen in one's surroundings can potentially lead to allergic reactions.

Understanding Wallemia Allergy and Food Restrictions

Wallemia is a type of fungus that can cause allergic reactions in sensitive individuals. It is commonly found in air and dust, but it can also grow on food. Individuals with Wallemia allergy need to avoid certain foods that can exacerbate their symptoms.

Foods to Avoid

• High-Sugar Foods: Wallemia fungi thrive in high-sugar environments, so foods high in sugar can worsen allergy symptoms. This includes candies, pastries, and sugary beverages.
• Starchy Foods: Wallemia can also grow on starchy foods that have been stored improperly or for long periods. This includes breads, potatoes, and cereals.
• Dried Foods: Dried fruits, nuts, and spices can often contain Wallemia, especially if they have been stored in humid conditions. This fungus can survive the drying process.
• Fermented Foods: Wallemia can also be present in fermented foods like pickles, soy sauce, and kombucha.

General Tips

• Food Storage: Store food in airtight containers and consume them before their expiration date. This can help prevent the growth of Wallemia.
• Cleanliness: Maintaining cleanliness around the kitchen, particularly food storage areas, can help prevent cross-contamination of foods with Wallemia.

Avoiding these potential food sources of Wallemia and following these precautions can help manage and reduce the symptoms of Wallemia allergy.
