Wheekie I didn't answer your actual question haha Got off on a rant about careless product makers.
I think Oxbow and Kleenmama's are the safest bet for guinea pig food. As far as I know they don't purchase from these mass production pet companies, and they monitor what goes into their products more closely.
I presume there are always risks when you purchase products and foods that are grown, and manufactured by companies...but I think those two are our safest choices. I know not everyone can order online, but some vets, pet stores, and farm supply type stores are willing to order Oxbow in for customers if it is requested.
My pigs had been on very limited pellets for 2 months, and they have now been completely off pellets for about 2 months. They got where they just really didn't want them, and it wasn't worth me having 5 or 10 lbs shipped to me to sit and waste or get peed in. They would go days without even acknowledging them. Now, I provide them with tons of KM's bluegrass, 2 cups each of a wide variety of fresh veggies, and then treats through the day of some fruits, fresh grass, and additional veggies. It has worked for us perfectly fine. The pigs are all maintaining and gaining weight, and are happy, energetic, and healthy.
Just out of curiosity, and back to "off the topic"... Has anyone heard any updates on the Peter Pan and Walmart branded peanut butters? I notice they still aren't back on the grocery shelves yet, but I haven't heard a word as far as the investigation into it.
That whole ordeal gave us the push (since there was nothing else available!) to give all natural peanut butter without hydro. oil in it a chance, and I think we will probably just stick with it. Takes some getting used to, but we quite like it now. I sent back 4 lids from Peter Pan that we had here that matched the recall. The 4 of us had what was thought to be the RotaVirus like 3X in the last years and now I suspect it was our PB. I don't think I'll go back when it hits the shelves again.
