It depends:
If it comes from the USA, I know that FDA, EPA, and USDA have got my back. No worries there.
If it comes from China, a thorough sanitization and sterilization ritual is required.
Not this guy. I'm not trusting them. All my tanks, rdas, rbas, drip tips get an everclear soak, wipe down, and rinse in very hot water for a bit. I'm never in a rush to use them, so why not take the precaution. Plus it gives you a good chance to inspect the equipment. To each their own.
