Yes, potatoes can contain pesticides and other environmental pollutants.

However, many pet (and human) food ingredients — especially corn and wheat — are also at even greater risk than potatoes for containing hidden and deadly “natural” carcinogenic mycotoxins — like aflatoxin and vomitoxin.

It’s difficult (almost impossible) to find pet foods that are 100% risk free of all carcinogens. That’s because the environment for all of us today (humans and pets alike) is filled with dangerous chemicals.

There’s simply no way to completely eliminate all the risks.

That’s why in addition to feeding organic foods, we recommend rotational feeding for most dogs. Here’s how we describe the reasoning behind this important concept in our FAQ about Diet Rotation:

“Since there’s no such thing as a perfect dog food, it’s reasonable to assume every product is deficient or excessive in some way.

“Too much of one nutrient or too little of another. Plus many foods can contain traces of dangerous toxins.

“So, built-in flaws tend to be magnified when the same food is fed continuously — day-in and day-out — for a lifetime.

“By periodically switching dog foods, the unhealthy consequences of serving the same imperfect products can be minimized.”

Hope this helps.
