Sulfites are a common preservative used in dried mushrooms, and they can cause severe allergic reactions in some people. While sulfites occur naturally in fermented foods, they are also often added to dried mushrooms as a preservative. This has led to several product recalls as some companies failed to declare sulfites on their product labels, posing a risk to sulfite-sensitive individuals. It is worth noting that sulfites cannot be removed from food through washing, soaking, or cooking, and those with sulfite allergies should be cautious when consuming dried mushrooms or products containing dried mushrooms.

What You'll Learn
Dried mushrooms often contain added sulfites
In 2020, the Tiffany Food Corp. issued a recall for their Huangfushanzen Huang Mountain Tea Mushroom dried mushrooms due to the presence of undeclared sulfites. This recall was prompted by routine sampling that revealed sulfite levels high enough to cause a severe allergic reaction in sulfite-sensitive individuals. Similarly, in 2011, the California Department of Health warned consumers about Shirakiku Brand Dried Shiitake Mushrooms imported from China, which were found to contain sulfite levels more than ten times the mandatory reporting limit.
The addition of sulfites to dried mushrooms has sparked concerns among consumers, especially those with sulfite allergies or sensitivities. Sulfites are known to trigger allergic reactions in some individuals, ranging from mild symptoms such as headaches and rashes to more severe reactions, including anaphylaxis. As a result, accurate labelling of sulfite content in dried mushrooms is crucial to ensure consumer safety.
While some brands of dried mushrooms may not explicitly state the presence of sulfites, it is important to exercise caution when purchasing these products. Food labelling laws vary across countries, and in some cases, sulfites may not be declared on the label if they are naturally occurring. However, it is always advisable to check the labels thoroughly and make informed choices, especially for individuals with sulfite sensitivities or allergies.
It is worth noting that removing sulfites from dried mushrooms is challenging. Washing, soaking, or cooking does not effectively reduce the sulfite content. Therefore, individuals with sulfite allergies or sensitivities should be cautious when consuming dried mushrooms and opt for brands that explicitly state the absence of added sulfites, such as certain organic options available in the market.

Sulfites occur naturally in fermented foods
Sulfites are commonly found in dried mushrooms, and these can be naturally occurring or added during the drying process. It is important to note that sulfites occur naturally in fermented foods, and this is due to the presence of yeast which produces them as a byproduct of the fermentation process. This means that all fermented foods will contain sulfites to some degree.
Dried mushrooms, in particular, have been known to contain high levels of sulfites, and this has resulted in product recalls to protect consumers. For example, the California Department of Health issued a warning to consumers about Shirakiku Brand Dried Shiitake Mushrooms imported from China, as they were found to contain high levels of sulfites that were not disclosed on the product label. In another instance, the Tiffany Food Corp. recalled Huangfushanzen Huang Mountain Tea Mushroom Dried Mushrooms due to the presence of undeclared sulfites, which posed a serious health risk to sulfite-sensitive individuals.
It is worth noting that some dried mushroom products are specifically marketed as being free from added sulfites, such as certain brands of dried organic shiitake mushrooms. These products may still contain naturally occurring sulfites, but the absence of added sulfites is an important distinction for those with sulfite sensitivities or allergies.
While it is not possible to completely remove sulfites from foods, proper labeling is crucial to ensure consumer safety. Food labeling laws vary across different regions, and it is important for consumers with sulfite allergies or sensitivities to be aware of the labeling practices in their area. This information can help them make informed choices and avoid potential health risks associated with sulfite consumption.

Sulfite allergies can be dangerous
Sulfites are chemical compounds found naturally in certain foods but are also manufactured for commercial use as food preservatives or flavour enhancers. They are often used to slow browning and discolouration (caused by bacterial growth) in foods and drinks. Sulfites can trigger asthma attacks and allergic reactions, including wheezing, coughing, skin reactions, and rarely, anaphylaxis.
Sulfite sensitivity affects roughly 4% of the US population and is especially common among people with asthma, who may experience a worsening of symptoms. People with asthma are more likely to have reactions to sulfites, with about 3% to 10% of asthmatics experiencing adverse reactions. Sulfites can cause asthma-like symptoms such as wheezing, shortness of breath, coughing, sneezing, and chest tightness. In very rare cases, sulfites may cause anaphylaxis, a severe allergic reaction that requires immediate emergency care. Symptoms of anaphylaxis include flushing, a fast heartbeat, wheezing, hives, dizziness, stomach upset, diarrhoea, collapse, tingling, or difficulty swallowing. If not treated appropriately, anaphylaxis can lead to shock, coma, heart or respiratory failure, and death.
If you are diagnosed with a sulfite allergy or sensitivity, the best treatment is to avoid foods and medications that contain sulfites. Reading product labels can help you steer clear of them. Many countries require labels on foods, drinks, and medicines that contain sulfites, and food manufacturers must declare on product labels if their food contains more than 10 parts per million (ppm) of sulfites. Food that contains over 100 PPM of sulfite includes some dried fruits and vegetables, wine, and molasses. In many countries, it is illegal to add sulfites to certain foods like fresh salads, fruit salads, or meats like minced meat or sausage meat.
If accidental exposure occurs, treatment can vary based on how sensitive you are to sulfites. Some common treatments include antihistamines, rescue inhalers, corticosteroids, and sodium cromolyn.

Sulfite levels in dried mushrooms may be mislabelled
Sulfites are a common preservative used in dried mushrooms. While some sulfites occur naturally in fermented foods, additional sulfites are often added to extend the shelf life of dried mushrooms. However, the presence and levels of sulfites in dried mushrooms may not always be accurately labelled, leading to potential health risks for consumers with sulfite allergies or sensitivities.
Inaccurate labelling of sulfite content can have serious consequences. Sulfite-sensitive individuals may experience severe or life-threatening allergic reactions if they unknowingly consume dried mushrooms with high sulfite levels. This issue has prompted several product recalls, such as the Huangfushanzen Huang Mountain Tea Mushroom recall in 2020 and the recall of Shirakiku Brand Dried Shiitake Mushrooms in 2011, where sulfite levels were found to be up to ten times the mandatory reporting limit.
Food labelling laws vary across different countries, and these laws dictate whether the presence of sulfites must be declared on food labels. For example, in the United States, the California Department of Health requires that foods containing more than 10 parts per million (ppm) of sulfites must disclose this information on the product label. However, enforcement of these regulations can be challenging, and consumers with sulfite sensitivities must remain vigilant.
The accuracy of sulfite labelling in dried mushrooms is crucial for consumer safety. Individuals with sulfite allergies or sensitivities should be cautious when purchasing dried mushrooms, even if the label claims the product is sulfite-free. It is essential to stay informed about food labelling laws and product recalls to make informed choices and avoid potential health risks associated with undeclared sulfites.
