This essay shows the role of economics in the adulteration of food imports.The mechanism of impact in the model is the choice of input quality by exporting firms. One implication of the model is that conomic variables can be used to predict adulteration in food imports. The essay offers an application to US fish and seafood imports following the closing of fisheries in the Gulf of Mexico because of the Deepwater Horizon platform oil spill. Simulations show an increase in adulteration in fish and seafood imports after the Deepwater Horizon incident. Empirical evidence supports simulations' findings.
