Morrisons roasting Tin

It is metal, it is not poisonous. Manufacturers do not make roasting tins from poison.

Unless it has exploded it still works.

Well, I'm certainly not using it again. I don't know if it's a non-stick coating that has come unstuck but it doesn't look like something that you should be eating.

I have bought so-called nonstick cooking tins and unless you pay a good deal of money for them the nonstick invariably wears off.

I got so fed up with regularly replacing tins that I bit the bullet and invested in some Pyrex roasting dishes.

I do agree that the coating might not be poisonous but you don't really want to serve it up with your gravy!

Non stick coatings aren't metal, they are usually PTFE (Teflon is a brand name of this), a polymer. They are almost entirely inert, in other words they don't react with anything. So, they won't do you any harm if you eat some, though the appearance and texture of the food would be a bit odd.


If you get them too hot (eg if you don't put any oil in a pan and burn the food) I seem to remember that PTFE can break up into small particles, and if you breathe these in it can damage your lungs (because your lungs are sensitive to small particles of anything, not particularly because of any property of PTFE).


The main issue with PTFE flaking off is that the pan won't be non-stick any longer, and also suggests it wasn't applied that well in the first place. It's difficult to attach PTFE to the metal, you basically have to modify the chemistry of one side of the polymer so it will create a bond. I'm guessing that Morrisons do this as cheaply as possible, so it may be less effective.

They did say they'd get in touch with the supplier so I suppose they buy them in probably from China as it was very cheap.

I seem to recall a while ago (years back) reading about non-stick killing parrots when heated. but forgot about it until now.

I think that birds are generally more vulnerable to air pollution than mammals (hence the use of canaries in coal mines) so that is plausible. Ordinary cooking e.g. frying shouldn't reach a high enough temperature for it to be an issue though.

Why?

It was cheap but it isn't safe. I don't want another as I think it's possibly hazardous.

Because it was very cheap, it may not be worth pursuing, but if it was relatively expensive, it would be worth pushing for a refund.

They shouldn't be selling stuff like it for food use.

It's just another backwards slide into safety standards being compromised as far as I am concerned.

I think some responses in this thread are quite odd. OP has made it clear that the main concern is the peeling layer making the product unfit for use. It doesn't matter whether it cost £2 or £200. It should be fit for purpose. It maybe that the problem is cosmetic but metallic gravy is even if not poisonous is not what you want to give family or guests. In any event it has happened more than once, others have found the same problem, so perhaps its sale should be reviewed until the problem can be determined and/or fixed. Why is that, in any way, unreasonable?

When I have purchased cheap roasting trays I've always put silver foil on them as they have always been rubbish with the coating coming off.

Where do you think the non-stick coating goes when it wears out which has happened since it first appeared...in frying pans for example?
