Rice with both live and worms

We had to bin the all some rice as it was full of worms, I believe the other packs have to return them because clearly we'll eat worms, both live and dried worms. I've worked at the retail before, anything that expires in a month or too that is food should be removed from the shelves, fine I can blame President Hyper Krugersdorp for but question is when were these products delivered at this retail store because we've never bought any all some rice that expires in 6 months or in a year, it's always in a month or too. I'll also write this for President Hyper Krugersdorp too
