heres some quick stuff i found, I'm actually going to email them tho.. but they speak on another preservative question here so i feel like they're aware people expect more out of them.. ill know soon enough
Is the fishmeal used in your products preserved with Ethoxyquin?
Our fishmeal ingredient is preserved with Naturox, a natural antioxidant, at the time the fish is processed to prevent rancidity on the trip to the manufacturing facility.
What is Ocean Fish Meal?
The ocean fish meal used in Solid Gold foods is Menhaden Herring, sourced from the Atlantic Ocean.
Where are Solid Gold’s products made?
All Solid Gold dry dog and cat foods, treats and supplements are made in the USA. Our tuna based canned cat foods are made in Thailand in facilities that manufacture human consumption tuna and meet our high quality and safety standards.
Do you use any ingredients from China?
No – Solid Gold does not utilize any ingredients from China.
Are Solid Gold ingredients “human grade”?
While “human grade” is not a legal term that can be used in conjunction with animal feed manufacturing, we utilize only high quality ingredients that pass strict quality control measures.
What is Meat Meal and why do you use it?
Meat meals, such as lamb meal and chicken meal are meats that have been cooked to reduce the water and fat content, making them a supersized protein source. Fresh meats contain approximately 70% water, which is eliminated during the cooking process.
Example: Whole chicken contains about 70% water and 18% protein. After cooking, the resulting chicken meal contains just 10% water and 65% protein - nearly four times more protein than whole chicken.
We only use specifically identified, high quality meat meal from certified sources.
