Campylobacter??


When asked what is the typical pathogen associated with poultry most of my students will answer Salmonella but there is another pathogen that is also likely to cause illness in customers, Campylobacter. This bacteria is found primarily in poultry; chicken, duck, turkey and game birds are all effected. It is found in healthy poultry stocks, in some cattle and sheep, dogs and it has even been found on farmyard flies. It does not effect poultry but can cause some reproductive problems for cattle. From 20 - 100% of chicken have it in their systems. Even free ranged poultry and wild birds will have it regularly. It is found more typically in industrialized countries but it may or may not have anything to do with modern farming techniques. It is also easily spread through wild populations.
The bacteria, more specifically Campylobacter jejuni, is a major cause of intestinal distress in humans. Estimates are from 2 - 4,000,000 people are effected each year in the U.S. The disease causes gastroenteridis and includes symtoms such as diarrhea and vomiting and lasts about a week. Typical home diagnosis is "stomache flu". The bacteria takes about two or three days to incubate so tracing its source may be difficult.

So what can be done? Cooking to proper temperature, 165 F according to USDA guidlines, will destroy it. Storing meats appropriately with poultry on the bottom shelves or seperate from other meats, washing all contact surfaces properly, possibly using seperate cutting boards are all ways to prevent contamination.

It is estimated that about a 400 - 500 bacteria count is needed to bring on symtoms in some people. For others it is higher depending on the digestive health of the person. It is not typically lethal with few deaths occuring and only in those who have a compromised immune system.

Now the stinky part, Campylobacter is spread primarly through fecal matter. Animals raised in close quarters may be more likely to have it but free ranged poultry populations are very likely to have it too. Many chefs today like to cook duck to less than 165F, so be sure to rinse the exterior and sear the duck well to reduce risk. Ducks are defeathered and then dipped in parrafin to remove very fine down feathers. This may help to reduce risk but if they are eviscerated poorly there could still be problems. Fresher poultry is less likely to have a high bacteria count and keeping poultry very cold is also important. http://www.fda.gov/Food/FoodSafety/FoodborneIllness/FoodborneIllnessFoodbornePathogensNaturalToxins/BadBugBook/ucm070024.htm

What was in that bird??


The annual decision of buying a turkey for thanksgiving is done by millions of people. For most it requires a trip through the frozen bins at the supermarket, for others a visit to the local butcher shop to have the fresh bird, even less will seek out local farmers which have taken orders months ago, and finally those who purchase via the internet. So which is it? What did we eat this year? There are so many choices and price ranges. First lets start off with the standard commercial birds.

Most commercial turkeys are raised similarly to chicken. They are a single breed, the large breasted Holland White; this bird dominates the market and is raised in large crowded outdoor pens. They are typically fed a corn based diet with a soy protein mixed in. This premixed "ration" has vitamins, minerals, and a variety of possible antibiotics including tetracycline, various sulfates, bactracin depending on the grower or company that supplies the grower with feed. Many farms are vertically integrated with the grower being supplied the birds and feed from the processing company. But there are also small farmers that use many of the pre-mixed rations as well. The goal is rapid growth. The price of these birds is consistantly low. Hanaford supermarket was offering a turkey for $.40 per pound. Others are giving away turkeys with a purchase of a certain monetary amount of other groceries. But not all supermarket birds are the same either. Many offer fresh or organic, quasi niche market birds on the days just before Thanksgiving.
Natural - No added ingredients, after slaughter ( has nothing to do with feeding methods)
Naturally raised- This may mean a few different things but typically the bird was fed a ration that had no antibiotics or animal byproducts such as bone meal.
Naturally enhanced- Has a solution of salt, turkey broth up to about 10 % and often "natural" flavorings.
Enhanced- Turkey that is pumped with varying amounts of salt, water, sodium phosphates and flavorings. Most contain around a 12% solution but I have seen a higher and lower amounts.
"Super" Enhanced- Think Butterball, bird is enhanced with water, salt, sodium phosphate, but also hydrolyzed soy protein, autolyzed vegetable protein. These are basically nicer ways of describing MSG (monosodium glutimate) which are typically frowned upon by consumers.
All added ingredients must be listed on the label but the meaning of those ingredients is up to the consumer to research.
Fresh- This means the bird was slightly frozen quickly after slaughter but not frozen solid and should not require a thaw out.

Frozen- Bird is blast frozen right after slaughter and stored at 0 to -20F. Can be stored like this for many months without much harm.

Organic- Bird was raised without antibiotics, fed all organic ingredients, has more space to roam etc. ( organic rules are listed on the USDA web site)

As far as pricing goes, the least expensive is the basic naturally enhanced bird, next would be the phosphated bird and then the super enhanced product. Fresh birds are typically twice the price of regular frozen and organic were at least three times the price.

Brand names for supermarket birds may include the forementioned Butterball, Jennie-O, Perdue, etc. Many brands are actually owned by much larger meat companies such as Hormel , Tyson, Smithfield.

The top turkey producing states are listed below in order of production.
Minnesota
North Carolina
Arkansas
Virginia
Missouri
California
Indiana
Pennsylvania
South Carolina
Iowa

So what about the local butcher or specialty market? Most small butchers will sell a single brand that they consider quality. Often a non- enhanced small market bird. Brand names such as Jaindle or Bell and Evans, Eberling provide a quality that is considered higher than the larger market birds. The local butcher also provides cooking instruction and advice on how much to order. Small butchers are more likely to sell a variety of naturally raised birds and even local, very small market birds. Fleisher's of Kingston, near where I live prides themselves in knowing the farm where the turkeys are from and can guarantee the way they are raised. Some exclusive markets will offer heirloom breeds too.

For those who frequent farmer's markets there may be a poultry farmer who raises a few turkeys. These would need to be ordered in advance. The sizes may be varied and the price will be high but the fact that you personally supported a local farmer and you know exactly where the bird came from is something you can brag about to family and friends. Many small farmers are also selling "heritage" breed turkeys. Heritage breeds are those which have fallen out of popularity for one reason or another. They often require a longer growing time but have a deeper, richer flavor. Some breeds I've seen are the Standard Bronze, Blue Slate, Bourbon Red, Narragansett and Royal Palm.

Internet sales of turkeys are another way to purchase niche market style birds. There are hundreds of small market producers of heirloom, naturally raised, organic turkeys. They tend to be expensive and shipping is another part of it. Expense can be quite high for example a "WillieBird" organic turkey from Williams and Sonoma is $116 for a 18 lb bird. Other sites list birds from anywhere from $3.00 to $6.00 per lb. They come in styro boxes and shipping can be expensive also.
To avoid all of this decision making you could simplt take your guests out for dinner....but thats just the chef in me talking.

The world of turkey products seems to grow every year and its up to the consumer to really think about the purchase ahead of time. The good thing is you have more options than ever before.
