Parsley

Greek Tortoise

Testudo graeca

Greek tortoises (T. graeca) are noted by Tortoise Trust as particularly vulnerable to dietary imbalances; high oxalates in parsley risk disrupting calcium metabolism. Tortoise Trust recommends only occasional use of high-oxalate herbs.

Yellow-bellied Slider

Trachemys scripta scripta

Yellow-bellied sliders share the same dietary pattern as red-eared sliders; parsley's high oxalate content makes it unsuitable as a staple vegetable. Occasional small offerings are acceptable but should not displace lower-oxalate leafy greens.

Hermann's Tortoise

Testudo hermanni

The Tortoise Table does not list parsley in its safe or moderate categories for tortoises, and Tortoise Trust explicitly recommends limiting high-oxalate plants like parsley for Mediterranean species. High oxalate load can impair calcium absorption despite parsley's high calcium content.

Red-eared Slider

Trachemys scripta elegans

ReptiFiles and Tortoise Trust aquatic turtle guidelines do not list parsley among recommended greens for red-eared sliders. The high oxalate content can impair calcium absorption, a concern for aquatic turtles requiring adequate calcium for shell health; occasional use is acceptable.

Sulcata Tortoise

Centrochelys sulcata

ReptiFiles does not list parsley among approved Sulcata foods, and the species' grass-heavy, high-fiber dietary requirements leave little role for high-oxalate herbs. Tortoise Trust's oxalate warnings apply; occasional small amounts are the maximum advisable.

Painted Turtle

Chrysemys picta

Painted turtles consume plant material as adults but benefit from low-oxalate options to support calcium availability for shell integrity. Tortoise Trust aquatic turtle guidelines do not recommend high-oxalate herbs regularly; parsley can be offered occasionally in small quantities.

Leopard Tortoise

Stigmochelys pardalis

Leopard tortoises are grass-heavy grazers and high-oxalate herbs like parsley are not appropriate as regular dietary components. Tortoise Trust highlights oxalic acid risk for chelonians broadly; Merck Vet Manual supports fiber-rich, varied plant diets with caution on antinutrients.

Eastern Box Turtle

Terrapene carolina

Eastern box turtles are omnivores whose plant component benefits from variety, but parsley's very high oxalate content (1313mg/100g) can inhibit calcium uptake if fed frequently. Tortoise Trust's caution on oxalate-rich plants applies; occasional use is acceptable for this species.

Russian Tortoise

Agrionemys horsfieldii

Parsley has high oxalate content (1313mg/100g) which can bind calcium and contribute to urinary/renal issues with frequent feeding. Tortoise Trust advises limiting high-oxalate foods; occasional use alongside calcium-rich, low-oxalate staples is acceptable.

Red-footed Tortoise

Chelonoidis carbonarius

Red-footed tortoises tolerate a more varied diet including leafy herbs, but the high oxalate content of parsley (1313mg/100g) still warrants limiting frequency. Tortoise Trust's oxalate guidance applies across herbivorous and omnivorous chelonians.
