The food chain model consists of four types: prey, intermediatepredator, infected intermediate predator, and top predator. We studied the solutions for the originalmodel and positive and bounded solutions in the sub models. Also found equilibrium points withsufficient and necessary conditions. By using Jacobian matrix and Lyapunov function to providelocal and global stability. Can use the harvesting to control the disease and it can be used as tool toprevent disease transformation into an epidemic. Finally, some results were illustrated in numericalsimulations.
