Stewart itself is made in the USA (Dayton, Ohio). Other verified USA-made single-ingredient freeze-dried beef liver options include Vital Essentials, Primal Pet Foods, and Northwest Naturals. Be cautious with brands that claim "packaged in USA" rather than "made in USA" — these are different claims and the distinction matters if sourcing is your concern.

Why USA-made matters for this product
For raw meat-based pet treats, country of manufacture is a meaningful safety consideration. China-manufactured pet treats have been associated with several illness and recall events over the past 15 years (the FDA investigated thousands of illnesses linked to imported chicken jerky treats from 2007–2015). The FDA issued specific guidance urging pet owners to look for treats made from US-sourced and US-processed ingredients.
A "Made in USA" claim on pet treats means the product was manufactured domestically. It does not automatically mean the ingredients were sourced in the USA — but for most legitimate manufacturers, the full supply chain is domestic. Reading the fine print matters if you want ingredient origin as well as manufacture location.

How to check sourcing claims
Look for three things on the packaging or website: (1) Where is the product manufactured — not just packaged, not distributed, but actually made? A specific city and state is more credible than a vague "manufactured in the USA." (2) Where is the beef sourced? "USDA-certified" and "USA beef" are meaningful claims. "Natural" and "premium" are not sourcing claims. (3) Who makes it? Companies that manufacture in their own facilities (like Stewart in Dayton) have more control over the process than brands that use contract manufacturers.
Warning signs of misleading labeling
"Packaged in USA" means the treat was made elsewhere and bagged domestically — not what most people want when they seek USA-made products. "Natural" is a USDA-regulated term for meat products but does not specify origin. "Imported ingredients" in fine print alongside a USA flag on the front of the bag is a red flag. "Manufactured for [company name]" without a facility location indicates contract manufacturing where sourcing may be opaque.
When in doubt, contact the manufacturer directly. Legitimate quality-focused brands will tell you where their beef comes from and where the product is made. Evasive or vague answers suggest the supply chain may not meet your requirements.
The bottom line on Stewart vs alternatives
Stewart's Dayton, Ohio manufacturing and USDA-certified beef sourcing make it one of the most transparently USA-made options in this category. Its 50-year history in freeze-dried treats means the manufacturing process is well-established rather than novel. For owners prioritizing USA sourcing, it is the default recommendation in this product category.
The alternatives listed above are genuine options if Stewart is unavailable, if you want a different protein source (Vital Essentials offers multiple), or if you want to compare the sourcing claims directly. All of the brands in the table above stand behind their USA-made claims with verifiable facility information.
