I think that mayonnaise is falsely thought of as being the culprit in
food poisoning cases; I think that is a myth.

Right. I would think that cyanide, for instance, would be

I used to write a silly "Roses are red, violets are blue" type poem in
the kids' lunches from time to time ("Roses are red, violets are blue,
I made this sammidge, Just for you!" fer instance). Years later, the
male child unit told me that he used to disgustedly say to his
tablemates, "Aw, jeez, would you look at this stoooopid thing my
mother wrote?" when he was actually pleased as punch :-)

Didn't you ever make sandwiches as a child and ride out on your
bicycles far away on a hot summer's day for a picnic?
The sandwiches would be in your backpack and would be hot by the time
you reached the destination, but they tasted great. Boiled eggs too,
and all sorts of meat.

How big a risk to your children's health is acceptable to you? Sure not
every mayonnaise that gets warm grows poisonous bacteria, but some
does. There are enough risks to my kids' health that I can't control,
but by gum I'm going to minimize what I can -- and letting meat or mayo
get warm is one risk I can eliminate.

WHY do you think mayonnaise is a danger? The pasteurized eggs? The
oil? What? And why are any of us here, us precious cargo, who ate
tuna sandwiches at lunch all the time.

Mayo isn't processed for sterility when bottled. It's stored and sold
at room temperature. It's most assuredly not a good culture medium for
bacterial growth as the pH and extremely low water activity contribute
to a bacteriostatic environment. Mayo is warm when it's made, when
it's warehoused, when it's displayed in stores.

It's the stuff served with the mayo that can grow the bacteria.

Default Don't let meat or mayo get warm

When I was a kid, my neighbor's Mom was from France. When we wanted mayo
for a sandwich, she would whip up a couple of egg yolks and lord knows what
else for our sandwiches. (And we ate it, raw eggs and all.) My
understanding is that real mayo is made in such a way that very bad things
could happen if left at room temperature but the stuff we buy off the shelf
is hardly the same risk.

I think the question is one of "acceptable" risk. Commercial mayo is
made with pasturized eggs (eliminating for the most part, the risk of
salmonalla). Most egg warnings have to do with uncooked home prep.
Even with helmets, which seem like a good idea, kids on bikes can/will
suffer injuries. If some fall while climbing a tree, one could cut
down all trees. I'm amazed that, in this era of litigation for
*everything* that schools are still allowed to have sports programs --
surely concussions, drowning, broken limbs, etc. are ever present
dangers. Can't fault keeping "hot foods hot and cold foods cold," but
unless one follows one's kids around, who knows when they're going to
trade PB&J for tuna salad? On one hand, I think we moderns are
over-fussy about various 'safety' concerns. OTOH, I understand why
some want to sterilize and/or pad everything a child comes in contact
with. Minimizing risks is reasonable and thoughtful; eliminating them
is impossible and fidgetty.

Quibble. The only part of mayo that's pasteurized is the egg. The
finished mayo is just the way the laws of physics makes it. No
processing after manufacture and no processing during manufacturing to
go any further than homemade.

And here's the reason we're told to refrigerate it. Not because it's

Eggs can be held at room temperature for days and even weeks. As long
as they're cooked through at service.

You were given bad info. Homemade mayo and commercial mayo are made
essentially the same way. The only differences are that commercial
mayo has pasteurized eggs in it. If you make mayo at home and let it
stand at room temp for a couple days, the pH and water activity levels
will essentially sterilize it. Or, you can pasteurize the eggs at home
if you really want to. <http://www.hi-tm.com/Documents/Mayonnaise.html>

When you say "left at room temperature" how many weeks you tawkin'?

Commercial mayo (ie. Best Foods, etc.) sits on the stupidmarket shelf often up
to a year, and longer, before it's purchased, and not necessarily in a climate
controlled envionment (many markets aren't air conditioned), and those mayo
jars are NOT vacuum sealed (so make sure that plastic band is intact). There
is no reason one could not remove the lid from a jar of mayo, scoop out a blob
with a clean implement, replace the cap and leave it out on the counter for
many months... that mayo will not spoil if that's all that occurs... but that's
not what occurs, folks poke food laden implements into the mayo, deep down and
stirred about as they do their scooping... the mayo quickly becomes
*contaminated*, and so the manufacturers recommend refrigeration. If homemade
mayo were prepared under sterile conditions with pasterized eggs then it would
not need refrigeration either, but duplicating those conditions at home is just
not a possibility.

Plain mayo in of itself just doesn't breed bacteria all that quickly,
especially not commercial mayo... it's primarilly what's mixed with mayo that
affects spoilage, especially in the short term... the typical tuna salad
sandwich prepared in the AM and stored at room temperature for a school lunch
just will not breed enough bacteria by noontime to cause illness... a tuna
salad sandwich left at room temperature for 5-6 hours will not cause someone
with a normal immune system to become ill, but left in the school desk until
the next day's lunch (or out in the hot sun all day at a picnic) is not a good
idea.

When you say don't let the mayo get warm, how warm you tawkin'... shit, yer
fridge is warm compared with your freezer.

When you change the subject of a thread, could you please indicate:

a. The original subject title eg. "Don't let meat or mayo get warm
(Was "...former subject line...")

and

b. the poster you are quoting?

Sorry to disillusion you, but most food poisonings from potato
salad/tuna salad/etc were probably made with commercial mayonnaise,
because how many people do you know who make their own?

Once again, you talk crap, Cookie. Commercial mayo isn't made under
"sterile conditions" and it doesn't need to be. The low pH and low
water activity make it unnecessary. Commercial mayo wasn't always made
with pasteurized eggs and it was just as safe and just as free from
spoilage. Now they use processed eggs to add another layer of surety.

Anybody who's concerned about bacterial contamination in eggs can
pasteurize them at home. I posted a URL earlier about that. But it's
simply unnecessary. Let your homemade mayo sit at room temp for a
couple days and the bacteria die.

Commercial mayo is made with eggs that have been lightly frozen
because some food science wizard discovered that those eggs could
emulsify more oil. There's less egg in commercial mayo, volume for
volume, than homemade.

Sylvia, you're using the wrong premise to make your point. It isn't
the mayo that's spoiling. Not homemade nor commercial. It's the other
stuff, the "diluents" that foster bacterial growth. The mayo is
actually keeping the bacterial growth down because of its
bacteriostatic properties.

Or other dishes prepared on the same surface (or using the same

That would be logical *if* mayonnaise were responsible for "most" food
poisoning. From all I've been able to gather, these picnic salad-based
incidents are much more likely to be caused by plain ol' food
mishandling involving *other* contaminated items. Raw eggs *can*
harbor salmonella; therefore homemade, raw-egg mayonnaise is a (slim)
possibility.

A CDC report on salmonella, citing just under 1,100 cases in 1999,
says "Of the 19 outbreaks in 1999 for which a vehicle could be
confirmed, 15 (79%) were associated with shell eggs; implicated
vehicles included lasagna, ice cream, tira misu, stuffing, and
manicotti. Between 1993 and 1998, an average of 82% of
vehicle-confirmed outbreaks have been egg-associated."

http://www.cdc.gov/ncidod/dbmd/disea...ECSTE99web.pdf

However, the detailed table of suspected or confirmed food causes
shows only ONE that mentions a mayonnaise-based salad (chicken). The
other egg-containing foods include lasagna, freedom toast(!), Chinese
burrito, and quiche.

Nope. I don't think I'm going to worry about an unrefrigerated tuna
salad sandwich any more.

Thanks for the link. I have stayed away from sauces and recipes with raw
eggs in them. I feel better now and pasteurizing them doesn't seem
complicated at all even if it isn't really needed.

They already know. Consumers in North America expect eggs to be
refridgerated. And won't buy them unchilled. Same with low sudsing
detergents...work better but no suds no sales. Applies to many consumer
goods, you have to sell what the consumer wants and how he wants it.

Not really. You can't guarantee that people will cook eggs thoroughly
before eating them. Eg. poached eggs, it's even possible that
scrambled eggs won't be cooked sufficiently. It's better to
refrigerate the eggs and keep the bacterial load down in case of that
rare contaminated egg. Additionally, you are talking about bacterial
growth- what about other quality deterioration issues that would be
slowed down by refrigeration, especially in the summer?

Yeah, really. Until about 50 years ago, retail eggs weren't
refrigerated at all. Country stores around here sell them out of 15-
or 30-dozen egg boxes displayed on the sales floors.

Eggs will effectively be sterile by the time they reach 160F. They
aren't coagulated at that temp. Scrambled eggs will be over 180F. But
sterility isn't the need. Only reduction of total bacterial counts. So
cooking "thoroughly" isn't necessary.

As for guaranteeing that people won't cook eggs thoroughly, it's not
the job of the chicken, the farmer, the shipper the store or anybody
else to make sure that the consumer protects himself. "Cover thine own
ass" is good advice.

It's not a question of whether anyone makes sure that a consumer
protects her/himself. It's a question of selling or not selling
pathogen-laden eggs. It is most certainly the job of the farmer, the
shipper, the store, the restaurateur to make sure that they do not
foster the growth of bacteria in the food that they handle. No one
should sell spoiled food expecting that everything will be fine if the
consumer cooks it correctly.

"Cover thy ass" is a good advice for people who sell products too.

She sure can! In fact, that is the problem: salmonella that gets
*in* the egg as it's formed. External salmonella is reduced by
washing of the eggs.

Depends on which state and which season. Growth of bacteria is
related to ambient temperature as well as time. Refrigeration keeps
the eggs in a safe temperature zone.

This is not a contest with Bob, nor do I wish to see anything happen

with my analysis whether or not anyone I know personally gets
salmonellosis. Bob is great on the facts and how things should go if

Even with refrigeration, eggs are cheap enough. Frankly, it boggles
my mind that you're arguing *against* a reasonable public health
regulation (that also maintains the quality of the product), for the
sake of some hypothetical savings to grocery stores.

"Eggs will remain safe for consumption"... with qualifications. The
problem is those qualifications are not always met.

Refrigeration retards bacterial growth.

I agree that the real world is a different place than an ideal.

Here's a paper on the subject:=20
<http://animalscience.ucdavis.edu/Avian/psym986.pdf>
And a puzzling quote from it...
"Several recent studies related to cooling of eggs have provided=20
further insight into the importance of cooling of eggs. Gast and Beard=20
(1992) orally inoculated laying hens with a phage type 13a strain of=20
SE. (Table 5) One group of eggs from the inoculated hens was sampled=20
on the day of collection, one group was held for 7 days at 7.2=B0C and a =

third group was held for 7 days at 25=B0C. Only 3% of the freshly laid=20
eggs and 4% of the eggs held for 7 days at 7.2=B0C were contaminated=20
with SE. However, 16% of the eggs from the 25=B0C were contaminated with =

SE. Contaminated eggs from all three groups contained relatively small=20
numbers of SE (less than 10/ml and rarely exceeding l00/ml).=20
Nevertheless, longer storage periods likely would have produced

with SE also observed substantial growth in eggs stored at room=20
temperature for 2-3 days. However, minimal or no growth occurred in=20
refrigerated eggs at 4=B0C."

My question is where did the increased contamination in the stored=20
eggs come from if the initial samples only had 3% contamination.

Well, be that as it may, in spite of the very small amount of=20
contamination likely, for general purposes, it's probably better to=20
keep your eggs cool, particularly if you don't use them quickly.

Well, I didn't exactly say send your kids with warm food and hope for
the best. I just don't think it's as huge a risk as modern people make
it. I even let my kids eat cookie dough! Not data, just an example,
but my husband will eat a cheese stick that was in our eldest son's
backpack all day, he has far fewer stomach problems than I do, and he's
willing to eat foods that I would toss. Every single child I knew
growing up survived the various sandwiches, salads, eggs, etc in their
lunches. The only kids I know who died, did so in accidents. I just
think we are overly sterile as a society now.

Ranee

Later on it said:

"These authors further found that refrigerated storage (4 C) was
necessary to reduce growth and rate of penetration into the egg. Some
researchers are now investigating new cryogenic approaches to rapid
chilling of shell eggs."

I.e., refrigeration reduced rate of penetration of SE into the eggs
(as well as growth). Although they didn't say it, I assume that
their determination of "contamination" was based on internal content
of salmonella so the increased contamination came from movement of the
bacteria from outside the egg to inside.

Your quote here is the only post of mine where I see the "=20" stuff.
I've posted in other groups today and none shows the "=20" thingy.

They leave a lot to conjecture about in the paper. I talked with my
scientist wife about that whole business of greater levels of
contamination depending on how stored and she said, "Huh? How did the
new bacteria get into the eggs so that storage was the determinant in
increase?" Same question I asked.

If washing the eggs got rid of surface bacterial contamination, where
did the "rate of penetration" even figure in the process? Lots of
questions.

Well, yes. It's a review paper, in which case the literature cited is
often not discussed in detail. The reader is left to obtain the
original papers to clear up specific questions.

> I talked with my

And they answered it. You said yourself:

"Bacterial contamination happens more frequently through the shell
that=20
by ovarian or oviducal contamination."

The bacteria are on the exterior of the shell at the beginning of the
study. As the study progresses, more move to the interior where they
are counted as contamination. Hence, an increase in contamination
with storage.

I didn't say that washing "gets rid of" bacterial contamination, it
reduces it. In any case, the article didn't mention if the original
study washed the eggs. To get the details, you'd have to pull the
original paper. Nonetheless, I don't think it's so unclear what
they're saying.

In my case, and I think it *may* be the prevailing rfc position, if I
have genuine doubts, particularly about a long-stored or
unrefridgerated food thing, I toss it because I know I won't be happy
trying to eat or serve it. If it smells "funny," I toss. A lesser
consideration in my case is 'official' food safety guidelines. While I
try to follow most of them, I don't say "ohmigod, I left the spaghetti
sauce 'cooling' on the stove for 4 hrs -- must toss," or "the sell-by
date was yesterday...." Experience with cutting those particular
corners hasn't been catastrophic. I understand that those who *have*
suffered genuine food poisoning are much more rigorous.

Maybe from the contamination that started before the washing

I dunno.

Most (all?) states Departments of Agriculture have adopted laws
requiring that eggs be refridgerated at 45F or below. Not sure if
ever made Federal law (yet).

Our cleanliness will lead to our deaths. More and more medications are
coming up worthless as we insist on taking shots/pills for everything.
