Informe de seguridad alimentaria: Wal-Mart hace 9 años • detalles 12 Comentarios Comentario Got one of their Walmart brand frozen pizzas. Within an hour or 2 of eating it, became extremely nauseous, had some vomiting, and it didn't stop until I took several doses of charcoal (which is what you'll even get in an ER for food poisoning).
