  "root_cause": "The FDA and USDA state that shelf-stable almond milk (UHT-treated) can last 1-2 months past the 'best by' date if unopened and stored properly, but once opened, it must be consumed within 7-10 days regardless of the date; relying on smell alone is dangerous because Bacillus cereus and other spore-forming bacteria can grow without producing off-odors, especially in refrigerated almond milk that is temperature-abused above 40°F.",
