Have you ever wondered what happens when your trusted bottled water brand faces a recall? Recently, the US Food and Drug Administration (FDA) announced a recall of nearly 79,000 cases of Fiji bottled water due to bacterial contamination and high levels of manganese. But what exactly is manganese, and why should we be concerned about its presence in our drinking water? In this post, we’ll dive into the details of this vital mineral, its role in our bodies, and the potential health risks of overexposure. By the end, you’ll be equipped with the knowledge to make informed decisions about your water consumption.

What is Manganese?
Manganese is a transition metal found on the periodic table, nestled between chromium and iron. It’s a hard, brittle metal that is abundant in the Earth’s crust and essential for all known living organisms. As a trace mineral, our bodies require manganese in small amounts for various functions, including antioxidant activity, wound healing, and bone development. Common dietary sources of manganese include peanut butter, spinach, and dark chocolate.
The Role of Manganese in the Body
Manganese acts as a co-factor for several enzymes, aiding in the metabolism of carbohydrates, proteins, and cholesterol. It also plays a crucial role in bone formation, blood clotting, and maintaining a healthy immune system. The recommended daily intake of manganese for adults is 2.3 milligrams for men and 1.8 milligrams for women. For children, these values are lower due to their developing brains being more sensitive to manganese’s effects.
### Risks of Excessive Manganese Exposure
While manganese is essential for health, overexposure can lead to serious health issues. The most common risks are associated with occupational exposure, such as in the steel industry or welding, where inhaling manganese dust can cause lung irritation and a condition known as “metal fume fever.” Symptoms include fever, muscle pain, and wheezing, which tend to subside over weekends and flare up during the workweek.
Chronic exposure to high levels of manganese can result in neurological symptoms, a condition known as manganism. This includes difficulty walking, muscle spasms, and hallucinations. Consuming too much manganese through food and drink can also lead to similar neurological complications.
Manganese in Drinking Water
Health authorities have set guidelines for safe manganese levels in drinking water. For instance, the Environmental Protection Agency (EPA) recommends that manganese levels should not exceed 0.05 milligrams per liter. Health Canada has set a Maximum Acceptable Concentration (MAC) of 0.12 mg/L to protect against potential health risks, particularly for infants and young children, who are more vulnerable to its effects.
The Fiji Water Recall
In March 2024, Fiji Natural Artesian Water voluntarily recalled nearly 1.9 million bottles of its 500-milliliter water due to higher-than-acceptable levels of manganese and the presence of three bacterial genera. The recall, classified as a Class III recall by the FDA, indicates that the product is not likely to cause adverse health consequences. The affected bottles were sold via Amazon and had production dates in November 2023.
What Should You Do?
If you have purchased Fiji water during the specified period, it’s advisable to dispose of it and contact Fiji Water for a refund. The company has assured consumers that the issue has been resolved and that the affected products never posed a significant health risk. However, it’s always better to err on the side of caution.
Conclusion
Understanding the role and risks of manganese in our drinking water is crucial for maintaining good health. While manganese is an essential trace mineral, overexposure can lead to serious health issues, particularly for vulnerable populations like infants and young children. The recent Fiji Water recall serves as a reminder to stay informed about the quality of the products we consume. By staying vigilant and informed, we can ensure that our drinking water remains safe and healthy.
