Petco to stop selling food/treats with artificial ingredients

I got a notice from Petco today that said, in part:
"Today, we’re making a commitment to not sell dog and cat food and treats with artificial colors, flavors or preservatives – making us the first and only major retailer of pet food to take a stand against such ingredients. We’ll start removing products that don’t meet our new standards in January 2019, and complete the process by May."
