How long does a jar of opened passata keep safely?

[GeorginaA]

Well - what the title says really. I like using it on pizza but certainly wouldn't get through a whole jar in 3 days like most jars say to use on opening. I know tomato puree kept in the fridge lasts a fair old while. Is passata the same or am I growing dangerous new cultures in my fridge (think my current open jar has been there for a month untouched and I'm making pizza tomorrow, lol)

4 days in the fridge
then Glaxo Wellcome come round and remove it for further research

Oh gawd... I'd better chuck it then, eh?

That's going to be an expensive pizza each month!

Oh well, back to boring tomato puree :(

Georgina - no good for this time but could you freeze it in ice cubes like you did for the baby purees? And then get however many ice cubes you need for a pizza each time?

5 days on the Sainsbury's ones

What I do is what Bozza suggests, just freeze it in pizza size tubs and defrost when needed.

yes, i do that it works really well. and get carton instead of jar, is cheaper.

Until you see mould on the top. I usually get 10-14 days out of mine - but in back of fridge, not in door. Am amazed at how many other people throw food out so quickly (how can you afford it? Seem to remember some people throwing out cooked rice after a mere 24 HOURS??!!). Have never in my life had food poisoning, so it can't be that bad!! :o

yes I was being flippant, easily a good week from a jar of passata

Agree with the back of the fridge bit though - only ever use the door for very short term storage, the temperature doesn't stay regular there.

The thing about something like passata isn't safety but spoilage. Mould will grow before and may it taste foul before it would cause food poisoning.

From opening it would have 14 days shelf life in the fridge (could go into all the boring science but won't bore you all to tears) but mould growth would be visible before this and would make it look and taste horrible.

(Before I descended into nappyland part of my job was determining shelf lives)

Yeah, but this passata was definitely there for over a month and no mould - not risking it though now!

What a bloody good idea re: icecubes! Going to do that with the next jar, definitely.

No mould - I'd use it... (Have done it before!)

I've seen really small cartons of passata - you could try to find those

if it tastes & smells OK then it's fine to use

Just doing meatballs and a jar of passatta that's been in the cupboard.not fridge. Smells ok no mould. Been open about a week..maybe less..will it be ok..teenagers and adults no babies eating it..
