Yes or no to pressure treated lumber?

Hey everyone.
I am going to build a couple raised garden beds and plant vegetables, no flowers.
So, my question is, is it OK to use pressure treated lumber for the box? I am going to line it with landscape fabric.
I looked on the new and there are some very strong opinions, both for and against.
I have had gook luck on the forum many times before, so please let me know your thoughts.

Thanks and take care

I wouldn't want those chemicals near my vegetables.

Use cedar. It would be a good compromise. That way you will only have the naturally occurring chemicals in the wood to worry about. It will kill you more slowly.

Acid rain and the pollutants that are constantly being washed out of our atmosphere are probably the greatest risk to our health nowadays, imo. Everything we eat, animal or vegetable needs and absorbs the chemicals in water. Unfortunately, water that is truly clean and pure is getting pretty hard to come by.

This fairly recent map of acid rain is pretty shocking.

I read somewhere awhile back that the richer the soil, the more apt it is to pull chemicals out of PT wood or creosote timbers. IMO it's best to use masonry.

There just is no reason you can not use pressure treated wood made after 2003.
There is no more arsenic being used to treat it.
Google "pressure treated wood for vegetables gardens" there's hundreds of study's and articles in gardening magazines dispelling the myths.

I have to agree with Joe on this. It's been many years since I was involved with the pressure treated industry, but I do know that it is safe and arsenic is no longer used. If properly treated the preservative chemicals are locked into the cellular structure of the wood and will not leach out any more than any natural occurring substance. I for one would not think twice about using it. Unless of course you want to rebuild your planters several times over though out the years.

Pressure Treated Lumber

Pressure treated 2x lumber not rated for ground contact will rot anyway.

Thanks everyone I appreciate your input and help.
I don't want to rebuild this thing in 4-6 years because it will be loaded with over 1000 pounds of dirt. That would be a giant PIA.

I will post some photos when I am done with in.
Again, thanks and take care
