Many carnivores in Jurassic World Evolution 2, like the Allosaurus, Indoraptor, and Tyrannosaurus Rex, eat live prey. Other predators, including Compsognathus and Dimorphodon, eat from carnivore feeders and piscivore feeders. These are the two types you have to keep an eye on.

No matter what you do, these feeders will get infected with E. coli, spreading the bacteria to your dinosaurs like wildfire. Usually in tandem, but not always, you’ll get notifications about feeders and dinosaurs being infected. A red box with a goat and meat symbol will appear above the contaminated dispenser letting you know it needs cleaning. 

Like with other ailments and injuries, dinosaurs sick with E. Coli will also have a red box appear above them, but don’t send your Mobile Vet Unit from the Paleo Medical Facility to scan for ailments or treat them just yet. 

Instead, to disinfect a feeder: 

Select a Ranger Team Click “Add Task” Click the contaminated feeder

Wait for the Ranger Team to clean the area first, then send in your MVU to heal your dinos. Cleaning your first feeder will unlock the E. Coli Dart Treatment, helping you treat further outbreaks more quickly. Just make sure your scientists are rested enough to research it quickly and keep your dinosaurs from dying. 

It’s not clear what triggers outbreaks. In most cases, it appears completely random, just as rabies or tuberculosis infections seem to afflict dinosaurs at random. E. Coli infections are more prevalent in flying dinosaurs, though, such as Pteranodon and Dimorphodon. Compsognathus will also contract the bacteria every once in a while. 

Importantly, E. Coli isn’t as transmissible as other diseases either. To test, I allowed one Pteranodon to remain infected inside and Aviary of six other dinosaurs, with only one other getting infected in about 10 minutes of game time. 

Now that you know how to disinfect feeders, your carnivores will be happy and healthy, increasing your park rating and appeal. For more on Jurassic World Evolution 2, head over to our guides hub for more tips.
