Frozen supplement shakes from Prairie Farms Dairy were behind a massive Listeria outbreak that killed 14 people and hospitalized 41 across 21 states. The CDC struggled for years to track down the source, but finally traced it to shakes served in long-term care facilities. The real kicker? The actual number of people affected could be way higher than reported. Scary reminder to always check those recall lists! #ListeriaOutbreak #FoodSafety #RecallAlert #HealthNews #Health
