Jerky lasts forever?
- Drying
- Freezing
- Preservative additives
These are further tests done by the manufacturer and typically revolve around water analyisis of the product. Once the product is finished, in order to be stable, it must fall below a known level of "free water". In order for the product to spoil, their first must be a "field" for the bacteria to grow in. So, remove the water, no field, product should/will last for quite some time. A lot of folks think this is some sort of new science the meat guys came up with, but in fact, the American Indians were the first to discover this trick. So, now we have the water below a threshold level, the bacteria has no chance of growing.
But wait......what bacteria? The bacteria I am talking about can be introduced during the process, post process, and or in the field at the point of sale. Some are fairly harmless, some can kill you. So, we need to go back and re-visit the process again. The environment that the product is manufactured in is critical to the shelf life of the finished product. Starting with a sanitary work room and equipment, that have been sanitized (not just washed). The USDA requires a cleanup water temperature of 180F. So, with all the "home made products" out there......this should be your first scare. No household has a hot water tank that runs at 180F, more typically they are in the 140F range.....This means, any bacteria present in the work space, is still present after cleaning....OK, so there are anti-bacterial cleaning agents out there......did they get all the bugs? And more importantly, did that homeowner clean all the soaps away?
Now we move on to the cooking process. While the Indians didn't take internal temperatures on thier product drying over the fire, the USDA requires it today. We have learned over time that the magic "safe" number for processed foods is 152F. Once the product passes this internal (not oven) temperature, the more dangerous bugs are dead. From the cooking process, back to that (hopefully) clean room for packaging. So here we are in the clean, sanitary room, and what happens if one of the packagers forgot to wash thier hands after using the bathroom? Biggest threat would be our (becoming more popular every day in the news) friend....eColi bacteria. This bacteria along with some others can hurt and even kill you. The point being.......don't think just because there are no mold spores growing on your jerky that it is safe to eat......
So, now that you now have a *general* idea of the process......why would anyone buy homemade products? It is very bothersome to me that in todays online marketplace, I continue to see "home made" products advertised, and selling! Seems folks think that because it is "home made" it is better than anything you could buy in the market. This thinking could kill you! Beware of the homemade products. Another bad one seen online is "too good to be true prices" on USDA products. These are typically distressed goods, meaning they are at or past the shelf date of the manufacturer. Typcial shelf life of beef jerky coming out of a USDA plant is 1 year. So, buying distressed goods, you are buying products that are over a year old. While this does not mean it will be harmfull to you, it will mean the quality of the product is past what it should be. And depending on the type of product, could harm you.Bottom line:Beware of home made food products, and when it comes to beef jerky, stay away from those "deep discounts", or at a minimum, ask the seller what the shelf date is.
But wait, I forgot..................Jerky last forever............right???
