Filthy Grilled Shrimp

The problem: If your picnic plans include grilling, leave the imported shrimp at home. Between the banned antibiotics, pesticides, bacterial residues, rodent hair, and insect fragments frequently detected in imported shrimp, it's one picnic staple that deserves to get left behind at the seafood counter.

The fix: Hunt down wild-caught American shrimp for the cleanest alternative to the stuff imported from South America and Asia, recommends the nonprofit Food & Water Watch. If you can't find any, take along some smaller filets of wild Alaskan salmon for a great dose of omega-3s that can handle the heat of any grill.
