SALMONELLA IN ORGANIC EGGS AGAIN

No, Salmonella has not disappeared from our eggs yet, much as everyone is trying and hoping (see all those posts I wrote during that huge Wright Farms egg recall in August, 2010).

The Minnesota Department of Health (MDH) and the Minnesota Department of Agriculture are investigating Larry Schulz Organic Farm of Owatonna and the eggs it produces. It seems that the eggs were only distributed to restaurants, grocery stores, food wholesalers and foodservice companies in Minnesota, Wisconsin and Michigan - not elsewhere.

Oh yes, the eggs are organic. I hope my very nice doctor at UCSF Medical Center is reading this (certified organic egg production keeps hens in free-range conditions: we had a related discussion last week when I saw her).

What we know so far is that the illness of at least six people (both children and adults) in Minnesota seem to be connected to eating this farm's eggs, and, that lab tests have turned up Salmonella Enteritidis in samples taken from the farm's environment with the same genetic footprint. Sounds suspicious.

And of course, as usual, and just to add to the confusion, our industrialized food supply means that they have been sold under several brand names: Lunds & Byerly’s Organic, Kowalski’s Organic, and Larry Schultz Organic Farm. The eggs are packed in bulk and varying sizes of cartons (6-egg cartons, dozen egg cartons, 18-egg cartons). If you want a full product descriptions and a list of stores where the suspect eggs were sold, go to www.mda.state.mn.us.

Well, that brings us to an important point again that I keep repeating: forget about sunny-side up eggs or other forms of undercooked eggs or foods that contain them (see The Safe Food Handbook for a long list - there is a whole chapter on Salmonella in eggs). Yes, they may taste great. But think of it this way: you'll taste them for say, 5 minutes, but if you get sick from Salmonella, you'll feel totally miserable for days.

STILL ANOTHER BAGGED SPINACH RECALL

All these incidents of bacteria in the U.S. food supply are wearing me out, trying to keep up. You may notice that most of them are in produce - which we tend to eat raw. That is, no cooking "kill step" for bacteria. And yes, today we have another one.

At least it's a change from Listeria. Church Brothers, of Salinas, California is recalling 560 bags of clipped spinach after one bag tested positive for Salmonella bacteria during a random USDA testing. The recalled product was processed on October 6, 2011 and shipped in 2.5 pound bags to Super King Markets in Los Angeles, California. The “best if used by” date is 10/23/11, but it's been for sale for a couple of weeks.

By the way, this is the second bagged spinach recall this year due to Salmonella - check my post for April 7. It was Fresh Express that time.

And wait...That name "Church Brothers" rang a bell with me. Ah yes, they were involved in the bagged lettuce recall(Listeria that time) just a couple of weeks ago. Church Bros. is part owner of True Leaf Farms by the way, which name may be more familiar to you in connection with that lettuce recall (see earlier posts). It seems that True Leaf Farms is their processing arm (I thought it was the other way around). And, in spite of sending food out with two different kinds of bacteria in the last few weeks, they pride themselves on their safety precautions.

Here's a quote from their website:
"Church Brothers and True Leaf Farms pride themselves with having the highest integrity when it comes to Food Safety Standards and we adhere to the Leafy Green Marketing Agreement standards."

Maybe they should double check. Obviously something is wrong.And I would bet we are going to hear more about Church Brothers' plant and their bagged greens.

NOW IT'S LISTERIA IN BLUE CHEESE!

Those deadly Listeria monocytogenes bacteria seem to be taking over the U.S. food supply. I can't say I am really surprised, given how many food service workers carry it and this bug's survival abilities. But it is really annoying. I am seriously thinking of going on a chocolate diet.

The latest is blue cheese. Fair Oaks Dairy Products, based in Northwest Indiana, today issued a recall of all its blue cheese produced under the Fair Oaks Royal Blue Cheese label. The recall applies to any cheese purchased on or after September 25, 2011. Thank goodness, the actual quantity of the cheese is only 20 pounds (but, maybe could expand). The cheese was distributed to retailers in Indiana, Michigan and Ohio.

This time it is the company itself which turned up the bacteria, or rather, an independent laboratory it hired did so during testing of the cheese (often it is the FDA's laboratories which find the contaminant). But why it took so long, I don't know. This is almost a month later, and there is a good chance much of the cheese has been eaten. But overall, the company seems to have acted responsibly, immediately contacting the FDA once it got the bad news.

If you live in these areas, and ate this cheese (it's in royal blue foil) watch for any symptoms. , Remember that symptoms of Listeriosis,which are a bit like the flu, can take anywhere from 3 days to 70 days, or occasionally, even 90 days to appear. Usually it's around 12 days to 3 weeks.

Oh, and by the way, Listeria monocytogenes in cheese - particularly unpasteurized cheese, is not at all uncommon.

THE CAUSE OF THE CANTALOUPE OUTBREAK?

Well, it seems that a tentative cause has been found for the Listeria bacteria contamination of cantaloupes all over the U.S.. This really bad outbreak has now killed around 25 people, made at least 123 people ill, and probably affected many, who didn't become ill, but may become carriers of the bacteria.

Investigators have zeroed in on the packing shed at Jensen Farms in Ohio. The Listeria monocytogenes bacteria has been isolated in samples taken from the cantaloupe conveyor belts, a melon drying area, and a floor drain. Now the question is: how did it get there? A packing shed on a farm is like a transit area, with a whole lot going on. So there are many possibilities.

It could have been in the soil covering the cantaloupes when they came there . Or, it could have been in the washing water (it wouldn't be the first time that washing water actually made produce less safe, rather than more safe). Or, it could have been that recently purchased equipment from another farm which had previously been used to wash potatoes. Or, possibly, it could have come from workers in the sheds who were carriers (a lot of people are). Or, even from a truck, parked too close to the packing shed, which could have brought Listeria from another farm or road or field. We may never find out.

The farm didn't do too well during recent government inspection in terms of other conditions as well. Among the things that government inspectors noticed were pools of water on the floor (which could be recent, after the farm closed operations), cloths used to cover the melons, inadequate cooling of cantaloupes, and rather worn out and hard-to-clean equipment.
And guess what, this farm had passed a recent inspection by a privates safety contractor with flying colors (the packing plant scored 96 out of 100).

So what else is new. This has happened before many times (for example, with that huge peanut outbreak that originated in Georgia). Why? The procedure is for the farm or plant to hire and pay the company that inspects. So, hum ha, you might say they were a little biased towards giving a good report. These procedures have to be changed, and inspectors everywhere have to be trained better (I go on about this in the book).

Of course, the Jensen brothers have gone out of business and are battling numerous law suits. I feel sorry for them. This can happen so easily.

ANOTHER TUNA FISH RECALL: AVOID THE TUNA SUSHI

Tuna can be a delicious fish, but also a dangerous one. I just came from the fish store. Tuna was on sale, but I decided to pass on it. It just didn't look perfectly fresh.

And that's the point: it's not just mercury. It's histamine. When tuna becomes spoiled - usually as a result of poor storage or handling - it can produce high levels of histamine protein which can lead to scromboid poisoning in people who are sensitive. (It can also happen with some other fish - see post of February 5 - "Tuna Steak Recall" for more details on these fish and on symptoms).

We currently have yet another recall of tuna for this reason. This time it is frozen ground tuna. Osamu Corporation of Gardena, California has recalled up to 1,800 cases, of frozen ground tuna because the FDA found decomposition in several samples of this fish. It also found high histamine levels in samples of the product taken from one retail location. I am assuming this fish was imported, as much of U.S. fish is these days, probably from Japan, but I have not been able to confirm this.

Apparently most of this product was distributed to companies that make sushi, especially for grocery markets, one of them mainly in California, the other with franchises in nearly every state in the U.S. Oh..Oh..

Watch out. One good thing - you don't need to worry for weeks wondering if you ate bad tuna and will get sick. You'll know pretty quickly - in under two hours, when the symptoms start (again - see the Feb. 5 post). The other good news is that usually it's not deadly, although it is very frightening. And people with liver problems, beware.

If you buy tuna, always make sure it is fresh, and don't let it spoil, or let the package defrost improperly if it is frozen. And if you are in a high risk group, and live in the U.S., avoid tuna sushi for a while, just in case contaminated products are still out there.

CONTAMINATED LETTUCE RECALL EXPANDS

This had not been a good couple of weeks for lettuce lovers in the U.S. And that just about covers everyone except me (I prefer arugula). What is more, the lettuce safety issue is becoming downright confusing. And, I am sure we haven't seen the end of it yet.

On October 1, I blogged the finding of Listeria monocytogenes in chopped romaine lettuce, produced by True Leaf Farms of Salinas, California, which issued a recall of its suspect products. Now there is another ready-to-use lettuce recall announced by Giant Eagle Farmer's Market, which is the largest supermarket in Western Pennsylvania. Giant Eagle is recalling eight ounce packages of Shredded Iceberg Lettuce as well as a number of deli products which used lettuce from the same lot, all with a use by date of October 14,2011.

Of course, they didn't grow the lettuce themselves. It came from a Salinas, California processor called River Ranch Fresh Foods, which, by the way, prides itself on its safety. The reason is the same as in the earlier (True Leaf Farms) recall - Listeria monocytogenes bacteria in the lettuce. But it's a different kind of lettuce. This company has not issued a recall of its lettuce, although it says it is co-operating with investigators.*

Now let's get to the broader issue. It seems that the problem is centered on lettuce from the Salinas area of California, with different kinds of lettuce involved. The question is: was the lettuce contaminated on the farm, or, at the processor's? It could be either. If Listeria got in at the farm level, that means it is probably in the growing environment, and could also affect other farms nearby. If it got in during washing, shredding or cutting at River Ranch, it could mean that this company has a contamination problem, and this could also affect lettuce from other farms that it is processing with the same contaminated equipment.

Either way, it is a bad situation. Listeria monocytogenes bacteria which can be deadly, especially to vulnerable people (such as pregnant women, newborns, those with weakened immune systems). And, remember that it can take as long as two months, and occasionally, even longer, for symptoms to appear.

So what are we to do? On my part, I have decided to avoid all California-grown leafy greens for a while until we find out more about where the contamination occured. And that applies to both ready-to-eat and whole (most would come from the Salinas area). I'll give up arugula too for good measure. Listeriosis is not something I want.

TSF

UPDATE: River Ranch has finally had to issue a recall of its Farmers Market and Hy-Vee brand iceberg, romaine and blended lettuce products. These salad products were distributed in Iowa, Ohio, and Pennsylvania and sold in retail supermarkets.

CAN'T WE EVEN PASTEURIZE MILK?

Our milk has been a lot safer from dangerous bacteria since we started to pasteurize it. Tests have shown that 2-25% of raw milk carries bugs like Campylobacter, Listeria monocytogenes, E.coli, Salmonella, Yersinia, Brucella, Mycobacterium bovis and Coxiella burnetti.

Some studies argue that these bacteria have become even more numerous in recent years as many dairy farmers in countries such as the U.S. give their cattle hormones to increase their milk production. This practice tends to result in more mastitis (inflammation of the udders). This is not just unpleasant for the poor cow, but results in more bacteria in their milk.

Thank goodness we have pasteurization. Sorry, for these reasons, I am not a fan of raw dairy, although I have known several people who are. (I also knew one person who died from eating raw dairy - cheese in her case). Pasteurization is a good aspect of our modern food supply. It is relatively easy to do, with heat treatment using one of several standarized methods (e.g. holding the milk at a temperature of 162 degrees Fahrenheit for 15 seconds).

So how could things possibly go wrong? Apparently they can. Farmers All Natural Creamery in Wellman, Iowa, in the United States, has recalled nearly 1,000 gallons of whole milk because tests suggest that it hadn't been properly pasteurized.

The milk was sold to four distributors — UNFI in Aurora, Colo. and Lancaster, Texas, Calma Optimal in Franklin Park, Ill. and Natural Brands in Wood Dale, Ill. Who knows where it went from there.
