Are you poisoning your animals??
Sodium triphosphate (STP, sometimes STPP or sodium tripolyphosphate or TPP,) is an inorganic compound with formula Na5P3O10. It is the sodium salt of the polyphosphate penta-anion, which is the conjugate base of triphosphoric acid. It is produced on a large scale as a component of many domestic and industrial products, especially detergents. Environmental problems associated with eutrophication are attributed to its widespread use.
Used in detergents!
The majority of STPP is consumed as a component of commercial detergents. It serves as a "builder," industrial jargon for a water softener. In hard water (water that contains high concentrations of Mg2+ and Ca2+), detergents are deactivated. Being a highly charged chelating agent, TPP5- binds to dications tightly and prevents them from interfering with the sulfonate detergent.
Also used in human food, dog/cat food??
The uses of sodium tripolyphosphate also include using it as a preservative. It can be used to preserve foods such as red meats, poultry, and seafood, helping them to retain their tenderness and moisture. Pet food and animal feed have been known to be treated with STPP, serving the same general purpose as it does in human food.
This is another good reason to refrain from feeding dog or cat foods to monitor lizards. It contains the same chemical additives as most frozen sea foods.
Commonly posts will appear on the forums about feeding canned or packet dog food to monitors. On a recent trip to Wal Mart, I read the ingredients on several different brand names of dog foods, Virtually all of it contains Sodium Tripolyphosphate. It is very harmful when ingested repeatedly by reptiles.
Feed only certified chemical free foods
This is more than sufficient reason to avoid canned goods and pre-packaged seafood items, why would anyone want to feed their lizard detergent phosphate??
