Fruit berries have no protection and as soon as they are picked they should be eaten.
The berries we buy have been well sprayed.
ALL berries purcahsed from another carries the person's who picked the berries diseases.
The finger print of every human and all their diseases that goes with this print is on every berry ever picked unless they use plastic gloves (they don't). So to stop the bacteria from the person's hands the berry must be refrigerated fast or as well sprayed with anti-bacterial poisons.
Try this, if you have an ozone machine, buy some fresh berries (not frozen) and put in a sink full of water with your ozone machine running in the water, soon you will begin to see the finger prints of the human that picked your fruit and the holes in the fruit where the microbes have entered to make their fungus home and mass reproduce the diseases of the human host that put them there.
Naturally a strong body can defend against such funguses, but the ill person with little Immune system makes a host for all these creatures that wait to consume us, the day we die they emerge and turn us back to dust.
