Since #7 doesn't actually mean "avoid," but rather "investigate further," I think you're proably OK.

Maybe there's some small amount of another plastic in the formula, like low-density polyethylene (LDPE), or something, that disqualifies it from the #5.

We moved two months ago, and since then I have purchased a ton of the OXO Pop containers for kitchen and laundry room storage (dog treats, chews, etc). Love Love Love them. The Container Store was having a sale (still is) and there is a free Pop rewards club. I got $15 off from just the rewards club on top of sale prices. I compared prices to Bed Bath and Beyond, and Amazon before purchasing. I also bought the ProKeeper coffee container and brown sugar container.

In case you are looking for glass alternatives, I use these Le Parfait jars for everything.

They are also available at The Container Store.

They come in sizes big enough to accommodate scoops and measuring cups.

These straight sided ones with wide mouths are called terrines. They don't come as large as the standard ones.

I decided against the Oxo plastic containers. Did not feel 100% safe as far as what they were honestly made from. I think they are "Tritan" plastic which is questionable... But not positive. Costco had a super good purchase on the OXO container set (warehouse price of $60 for 12 piece set) and I had originally bought 2 sets. But after finding out about the #7 plastic the POP containers were made from, I took both sets back. I will say they did seem like they would work well and keep things fresh. But in my particular case, I just did not feel "good" about using them.

Anyway, I bought all glass containers for the pantry. Ikea has tons of glass items that are reasonably priced so I bought a lots of those 365+ glass containers in several different sizes and they have a snap & lock lid. One is even a large 115 ounce size canister that will hold flour or other large bulk items. Filled in the rest of the pantry with a couple of the Anchor Hocking Cracker jars. Hobby Lobby had a good selection of US made Anchor Hocking glass. The large 1 gallon is holding flour right now and that seems like it will work well, Also bought some glass jars similar to the ones in the above message (Le Perfait) but from Ikea and they are called Korken. Glass with the wire closures and a rubber gasket.

All my old plastics and Tupperware containers are now gone. Including old plastic strainer / colander. Replaced with large Stainless Steel colander. I think it just makes me feel "better" knowing that from here on out I will just try to avoid plastics for food storage in my home. At my age, I am sure what ever (if any) damage has been done, but I do not want to add any additional to my system.

I freeze in mason jars all the time. As long as you use the straight-sided wide mouth ones you should be fine -- all mine are actually labeled "Freezer Safe" on the case. I mostly use them for freezing single-serving portions of large batches of chili, stew, etc., that I take to work for lunch.

I use glass for pantry storage. My thoughts:

- We know glass is safe. Why risk it?

- Glass containers look good in the pantry, and glass "matches" glass ... which isn't really true of plastic containers.

- Glass is available in a wide variety of choices: Mason jars for things that need to be air-tight, all sorts of other jars for other things.

- For leftovers, I bought a bunch of vintage Pyrex refrigerator boxes (they weren't cheap, but they're excellent quality), and now I store lots of things in one-serving containers.

I thought about using vintage Pyrex containers and read up on them. The set I purchased had 100,00 times the limit of lead allowed now. Check out all vintage products before using For food.

The way I see it, glass may be heavier and more expensive, but it is safest. Health has spiraled downward, with higher rates of infertility and cancer than ever. Previous generations tended to have the convenience of a slower lifestyle pace, buying and cooking fresh and organic, from market to table within a week, as was the only option at the time. As our day to days have gotten busier, our lifestyles have sought out convenience, leading to less healthy alternatives. Will it be a pain to reach for a 5 lb. bag of sugar in a glass container? Sure, BUT I would very much so prefer that over the "unexplainable infertility" struggles my husband and I are dealing with, and in an effort to avoid cancer or other types of illnesses in the future. Because when those are the trade offs, I don't see a question.

For that 5#bag of flour, it doesn't all have to go into one jar. I divide mine into two easier-to-manage jars.

What about aluminium / stainless steel contianers ? would that be a good alternative to Heavy glass jar ? I m debating hard to get rid of my oxo box, they are $$ when I got them.... I don't trust them entirely

, so I never put foor directly into OXO container , but I m stupid enough to keep them in a zip lock bag ,which is not so much better.
