European studies found the same kind of results. Astro BioBest yogurt started with the most - 794 million live bacterial cultures per gram (175 grams per container or 139 billion per container). But near the end of shelf life, almost two-thirds had died (794 to 260 million per gram or falling from 139 to 50 billion per container). Organic Meadow (100 to 6 million per gram) and Danone (180 to 120 million per gram or 32 to 21 billion per container) stayed above the million mark on each test. Liberty yogurt fared the worst, starting off low at just 118,000 live bacterial cultures per gram — and dropping to just 4,000 after two weeks.
