You know I actually have some sympathy for this woman. She's expected to meet tier 2 of the Food Act because it's a processed product. But if she was making the juice as she serves it, she'd only have to comply with Tier 1.
It's just fruit juice for chrissakes, not milk. As long as she's sterilising her bottles etc, the health risk is infinitesimal. The only other rule I'd expect her to follow is being transparent about it being unpasteurized.
