Lab tests of a breakfast cereal that is supposed to boost heart health have unveiled a toxic secret: it may be contaminated with a mold that has been connected with kidney cancer. Oats and oat cereal have been promoted as healthy foods because they allegedly protect the cardiovascular system. But researchers at the University of Idaho warn that more attention needs to be paid to the possibility that oat-based breakfast cereals are frequently contaminated with a dangerous mold.
An analysis of oat cereals being sold in the U.S. show they often contain a mold toxin known as ochratoxin A (OTA). Lab tests have indicated that OTA may cause kidney cancer. The scientists point out that OTA is one of the most commonly found mold toxins in the world. Other studies have indicated that the toxin sometimes may be found in dried fruit, pork, coffee, wine, and other foods. While it isn’t clear what kind of impact OTA causes for human health, the International Agency for Research on Cancer, a section of the World Health Organization (WHO), classifies this substance as a potential human carcinogen. Lab animals that have been exposed to OTA are prone to developing kidney tumors.
Interestingly, the European Union enforces the maximum limits of OTA in food. But the U.S. regulatory agencies do not measure or regulate the toxin.
A Deeper Look Into Ochratoxin A (OTA)
Ochratoxin A (OTA) is a mycotoxin, meaning that it is a toxic compound produced by certain fungi or molds. It can contaminate a wide range of food products, including cereals, coffee, wine, and even grape juice. This occurs as a result of fungal contamination in the field, during storage, or during the manufacturing process. When consumed in significant amounts, OTA may lead to serious health issues.
For instance, chronic exposure to OTA has been linked to kidney and liver damage, as well as an increased risk of various cancers. Furthermore, OTA may suppress the immune system and disrupt hormonal balances, further increasing the likelihood of developing chronic illnesses. In lab animals, long-term consumption of OTA-contaminated feeds has been shown to result in impaired kidney function and even death.
The European Union has set strict limits for OTA levels in food products, which vary depending on the type of food. For example, cereals and cereal products should not contain more than 3 micrograms of OTA per kilogram, while dried fruits and processed cereal-based baby foods should not exceed 5 micrograms of OTA per kilogram.
Tips For Reducing OTA Exposure
While it may not be possible to completely eliminate OTA from our diets, there are several steps you can take to minimize your exposure to this toxin. Here are a few suggestions:
- Store food properly: Mold growth occurs due to moisture and warm temperatures. Keep packaged foods in a cool, dry place and away from direct sunlight to prevent mold growth. Avoid leaving perishable food out in room temperature for prolonged periods.
-
Inspect food items before consumption: Check for visible signs of mold on food items, such as discoloration or a musty smell. If you suspect mold contamination, it’s better to discard the food.
-
Choose wisely: When purchasing food items like cereals and dried fruits, opt for well-known, high-quality brands to ensure that the products have been subjected to proper quality control measures.
-
Diversify your diet: Consuming a variety of foods can help minimize the risk of OTA exposure. Be cautious not to rely too much on a single food item.
-
Practice good hygiene in the kitchen: Clean your kitchen regularly to prevent mold growth in your home. Keep all surfaces and appliances clean and dry, and ensure that there is proper ventilation.
In Conclusion
While it is crucial for regulatory agencies and food manufacturers to remain vigilant in monitoring and preventing OTA contamination, it is equally important for individuals to take necessary precautions when it comes to their food choices and storage practices. By following the tips mentioned above and staying informed about food safety standards, you can protect yourself and your family from the potential risks associated with OTA exposure.
