The Not-So-Sweet Surprise: Methylmercury in Infant Rice Cereals Raises Concerns

Ah, the joys of parenting! From sleepless nights to diaper explosions, there's never a dull moment. And when it comes to feeding the little bundles of joy, we want nothing but the best. But what if I told you that our trusted infant rice cereals might not be as harmless as they seem? Brace yourselves, folks, because a study published in 2017 by the ACS' Journal of Agricultural and Food Chemistry has revealed a not-so-appetizing truth - our beloved rice cereals may contain a not-so-friendly ingredient called methylmercury.

The Mysterious Methylmercury:

Let's get down to the nitty-gritty. Methylmercury is not your average villain. No capes or menacing laughs here. It's a type of mercury that forms when industrial mercury gets cozy with bacteria in the environment. The result? A potent neurotoxin that's a real party-pooper for the little ones. You see, methylmercury likes to hang out in fish and shellfish, and when we munch on these aquatic delights, we become unwitting accomplices to its misdeeds. But hold on to your bibs, because rice has joined the party too! If rice is grown in soil contaminated with mercury, it can soak up this toxic tag-along.

The Startling Study:

Picture this: scientists armed with tiny spoons and an insatiable curiosity test 199 infant cereals for methylmercury. Lo and behold, the rice-based samples had some pretty hefty levels of this unwelcome guest. Particularly, rice from polluted areas in America and China had an average of 2.28 micrograms per kilogram. Yikes! The researchers also found that rice-based cereals had significantly higher methylmercury levels compared to those without rice, hinting that this grain might be the culprit.

The Not-So-Funny Effects:

Now, let's talk consequences. When it comes to the precious little ones, we want to give them every opportunity to thrive and shine. But methylmercury has other plans. Even low levels of exposure to this sneaky neurotoxin can lead to developmental delays and impair cognitive function in infants and young children. Imagine trying to conquer the world with a foggy brain and a delayed start - not the most auspicious beginning, right? And that's not all! Methylmercury can even affect fetal development if it crosses the placenta, potentially causing lifelong health problems.

Taking Control:

Alright, folks, it's time to take the reins and protect the little munchkins from this toxic intruder. The good news is that there are ways to minimise their exposure to methylmercury in infant rice cereals. Instead of sticking solely to rice-based options, parents can consider alternative grains like oatmeal or barley. These heroes are less likely to be contaminated and offer a tasty alternative. Oh, and let's not forget about other rice products, like rice milk and rice-based snacks, which can also carry significant levels of methylmercury. Keeping an eye on these culprits is a smart move.


While parenting is an adventure full of surprises, methylmercury in infant rice cereals is a surprise we could all do without. It's time for regulators and manufacturers to step up and address this concerning issue. Therefore, we need to be aware of the potential risks and take action to safeguard our little ones. Opting for alternative grains and reducing the consumption of rice products can go a long way in minimizing the risk of developmental delays and cognitive impairment.
