Exactly. Domestic production is regulated and certified by the US government, transported through short supply chains subject to auditing. Tampering with food supplies is very difficult to execute and harshly punished when inevitably detected. Food safety and consumer confidence are a high priority for commercial and public interests... you have never worried about watered down milk, you shouldn't worry about 100% domestic olive oil. Compared to imported goods... foreign governments are trusted to do their job before goods make their way through long and slow international supply chains. Plenty of time for undetected tampering before goods make it to American distributors. Tracking down diluted olive oil across an ocean is difficult, the other side has plausible deniability, the risk/reward of the crime is much better. I'm not saying our oil is better - just trustworthy. You get what the label says.
