I read this sentence 'We probably buy a variety of ground spices every month and when packaged spices of our choice are not available, we end up buying loose spices. This increases our risk of consuming adulterated spices.'
Ground spices means the spice has been ground down into a coarse or fine powder. However what's a 'packaged spice' and a 'loose spice'? I know ground spices are packaged small bottles or plastic bags or what am I not understanding?
