home food safety tests?
Comments (21)Im new to canning and food preservation. So much information..".to trust or not to trust." Yet even though I hear the bottom line is to trust only the approved testing, I find that I still have questions and have a hard time trusting my end product simply because of the possibility of human error. I read that there is a field test similar to a home pregnancy test that they use to detect botulinum in 20 minutes. Has this been made available to the public and if not, why? It's a great business plan if someone can come up with the science behind it. And Ill buy it. Home testing might also make it possible for others to continue testing since the government quit. But while we're waiting for that, I would like for someone to clarify some information. I know botulinum is the bacteria which produce the toxin (gases) that can hurt us. The bacteria die at a certain temp for a certain time. I have heard some people suggest to boil a home-canned product thoroughly after opening/before eating it to kill the bacteria, but this seems insufficient as the toxins would still be present. It is not the live bacteria that are toxic but the gases that they produce. Also the bacteria die when exposed to oxygen. Does boiling somehow neutralize toxins? Or is this just false information? Lastly, since bacteria produce gases, is it safe to conclude that jars tainted with bacteria would definitely have some outward visible signs of contamination? I know that other bacteria can infect food, but in my short studies I have been led to believe that botulinum is the hardest to kill. But do all bacteria produce gases and therefore provide some indication that food isn't safe?...See MoreI have a non-preserving food safety question
Comments (11)Thank you, everyone! I forgot the second step of posting last night. This was my reply to Lindalou: No, it was not cold at all. Now I am hoping I don't get sick from what I already ate before I noticed the fridge problem. OR the swig of spoiled carrot juice that alerted me. Luckily there is very little immediately-perishable food in that fridge -- it is mostly seeds, lotions, produce, cheese, stuff like that. Oh, dang, the figs are probably moldy. >Some food borne illnesses can take weeks to incubate in your gut. Can you tell me more about these, so I know what to watch out for? Or just names and I can google :). -- After I went to bed, I remembered I had also eaten fish oil and clam juice out of there. Scary! I had some kind of histamine response last night -- burning pain all over-- which decreased some when I took a prescription dose anti-inflammatory. It's still with me now, though. The pain kept me awake most of the night. It's like what I get when I eat gluten, but without the other symptoms. But there was no gluten. My immune system just does not like something in that stew of microbial toxins I ingested with my meals yesterday :/. No barfing or other GI stuff though, which I guess is good. Today's project: Throw out, clean out, move frozen foods out, thaw fridge overnight and see if that cures it or if I need a new fridge....See MoreFood safety
Comments (27)* A handy reference on the amount of bacteria that you can kill at different temperatures and cooking times is here: https://www.fsis.usda.gov/Oa/fr/95033f-a.htm?redirecthttp=true * I clean raw foods mostly with just water. I try to at least get any obvious layer of bacterial material to wash off by feel under running water. My general feeling on other techniques for cleaning raw food is that they either do far less than the people using them believe (e.g., vinegar will not kill many types of pathogenic bacteria) or for the ones that do work well - like oxygen bleach - I worry about ingesting that and killing off valuable gut micromes. You have to balance all of these issues of safety and convenience, and it's really hard to do this accurately. I have chosen to go with convenience. * I will confess that I eat a LOT of raw eggs and have never had a problem with them. Only in raw form do you get some of the nutritional advantages. This is by far my biggest food risk for pathogens. I have yet to get a single episode of indigestion. So even for high risk activities like this, the risks are actually pretty low. * For reasons I have never understood, oysters - even well cooked - cause me to throw up. Always. I'm not sure if that is some bacteria that survives cooking or if that is some other chemical agent that cannot be cooked away....See MoreFood safety of butcher block countertop?
Comments (12)Are you talking about the wood/butcherblock itself harboring bacteria, or the whether a particular wood finish for a wood/butcherblock countertop is food safe? You might try searching the Kitchen forum, because both have been discussed a great deal in many threads. Also, http://faculty.vetmed.ucdavis.edu/faculty/docliver/Research/cuttingboard.htm from which: "Our research was first intended to develop means of disinfecting wooden cutting surfaces at home, so that they would be almost as safe as plastics. Our safety concern was that bacteria such as Escherichia coli O157:H7 and Salmonella, which might contaminate a work surface when raw meat was being prepared, ought not remain on the surface to contaminate other foods that might be eaten without further cooking. We soon found that disease bacteria such as these were not recoverable from wooden surfaces in a short time after they were applied, unless very large numbers were used. New plastic surfaces allowed the bacteria to persist, but were easily cleaned and disinfected. However, wooden boards that had been used and had many knife cuts acted almost the same as new wood, whereas plastic surfaces that were knife-scarred were impossible to clean and disinfect manually, especially when food residues such as chicken fat were present. Scanning electron micrographs revealed highly significant damage to plastic surfaces from knife cuts. ... wooden cutting boards are not a hazard to human health, but plastic cutting boards may be."...See More- last year
