Looking for peanut free nuts or dried fruit?

We take peanut allergies seriously. That’s why we have super rigorous quality measures in place BEFORE WE EVEN ACCEPT a shipment of nuts into our facility.

Each lot of nuts must come with a quality certificate which shows through laboratory testing it is free of nuts.  When the truck arrives, we visually inspect all content to ensure none of the packaging has been damaged.  If all is clear, we accept the shipment.  If even one package has been damaged and has a hole, the entire truckload is rejected and sent back.

During our manufacturing process, we use a cleaning routine to make sure our Royal Nuts remain safe within our peanut free facility. Once we roast or pack a batch, we always use all natural cleaning products and hot water to clean our roasters and packaging machines after every run.

After production, the finished product undergoes more quality testing to ensure there is no presence of peanuts.

We recognize the importance of having peanut free dried fruit and peanut free nuts. That’s why we are working hard this winter to load up our peanut free nuts in a grocery store near you! Here are the stores that currently carry Royal Nuts.
