I just keep a spray bottle of restaurant sanitizer by the sink. Quaternary ammonium. Odorless, tasteless, harmless to people (when diluted), and doesn't attack fabrics or wood or metal. It's more effective than bleach at some things, less effective at others, but has few of bleach's problems. Spray on and let it air dry.

 

Are Thermapens water resistant? I have a Taylor thermometer in the same form factor that can be held under a sink and soaped up and rinsed off. It's nice to not have to be precious about washing it before sanitizing. 

 

Re: sponges ... these are the biggest failing in my kitchen sanitation. I like using them, but know there's no sanitary way to do so. Maybe if you kept them soaking in sanitizer, and nuked them every night and changed the sanitizer every day. But the time I tried that I didn't stick to the program. And I could never get my g.f. to stick to it. So basically, I use filthy sponges like most people do. And when I'm cooking a big dinner for other people I switch to my big stack of side towels, use them, and throw them in a pile to be washed.

 

Re: peroxide ...  I'm interested. I've seen a lot of literature on its use as a hospital and brewery disinfectant, but surprisingly little on food service use.

I use microfiber towels in the kitchen. I get them in bulk at Costco in the auto product area. 25 to a package.

They can soak up water like a sponge, scrub, you can wipe a counter without water beading being left. If it gets too dirty I grab a new one.

 

A new one gets put out every morning and at night it goes to the laundry room to dry if needed to avoid mildew. I then put into the next utility/cleaning wash load (no softener) and let them air dry.

 

They are also great for glass, no streaking.

 

I've always hated sponges especially that unexpected mildew smell left on your hands if you've handled a "looks clean but isn't" sponge.

That may be. But in the kitchen I'm not using them to dry, I'm using them as dishrags and counter wipes. When rung out well the damp microfiber sucks up water and spills and doesn't leave water drops and spots. It cleans off dishes well when hand washing. It makes for a great kitchen cleaning cloth, better than paper, cotton or a sponge.  I've used it with a mild bleach solution to sanitize. Still works great for me.

 

I use flour sack towels and side towels for other dry work.

 

I do keep the house cleaning microfiber towels separate from the kitchen ones. Yellow are for the kitchen and washed with other towels and air dried, blue and white are for house cleaning and are laundered separately to avoid lint .

 

I'll also throw this in as a tip. To get heavy soapscum off of fiberglass bath tubs and showers use Easy Off oven cleaner in the blue can. BLUE CAN ONLY!  Spray on a dry rub let sit for an hour while you do your other work then wipe with a soft nylon scrubber and rinse clean.

Tri-tip, cooked SV at 121F for 8 hours then seared, served with baked sweet potato (really a garnet yam) and salad.  Accompanied by a glass of Lodi Petite Sirah.

Just curious and please take this the right way:  8 hours at 121F seems a little on the edge of safety.  Douglas Baldwin recommends that the centre of the food should reach 130F within 6 hours to prevent the toxin producing pathogen C. perfringens from multiplying to dangerous levels.  I know you don't want your steak at 130F.  Others here have done tri tip at 125F for two hours and been happy with it.  cheers

I know, but I’m not really worried about the pathogens in the center of a solid piece of meat.  Hamburger etc. , yes.  I have done it from 121 to 131 and some of those “others here” would be me.

It's toxins produced by C. perfringens that are dangerous and the bacteria don't have to get to the centre of the meat to do this.  The reference to the temperature of the centre of the meat is just a means of demonstrating when it's safe.

I made an error somewhile back when I ordered a large Zojirushi.  I had not realized that the minimum quantity was one go (about 7/8 US cup).  While I can sometimes eat a go of rice I would have been much better served by the smaller model NP-NVC10 that has a minimum quantity of 1/2 go.

 

Usually when I make rice for dinner I leave the leftovers in the Zojirushi till the next night.

 

Safety Police here again!😇

i was brought up to speed about how cooked rice is not as benign as one thinks by the good folks here on Egullet.....y

Uncooked rice can contain spores of Bacillus cereus, a bacterium that can cause food poisoning. The spores can survive when rice is cooked. If rice is left standing at room temperature, the spores can grow into bacteria. These bacteria will multiply and may produce toxins (poisons) that cause vomiting or diarrhoea.

Let's not be serious!  I don't leave cooked rice standing at room temperature.  Nor in the refrigerator.  I leave leftover rice in the Zojirushi on the extended keep warm setting:

Well Jo I would want to know what temperature my rice is held at.  I do not know what that temp needs to be.  And yes I am serious in a helping kinda way. Cheers.

Went through to the keeper, as @sartoric might say.  I tried.

 

Above 63C is what I saw in the abstract of one paper.  I assume the Japanese have figured out what temperature to hold rice to prevent growth of B. cereus or they wouldn't have such a problem with excess old people.

According to the FDA's Bad Bug Book 48C (131F) is the maximum growth temperature for B. cereus, though one 1983 paper reported growth at 55C (a result that's never been successfully duplicated). It's not quite that straightforward, because this particular pathogen produces a heat-stable toxin, but in a scenario where the Zo is holding the rice at a higher temperature until service there's no opportunity for the bacillus to get a toehold.

 

For those of you who don't have it/didn't know, the Bad Bug Book is a free download in PDF form and well worth having on your computer, phone or Kindle for quick reference.

OK. Got a question. I took a package of chicken breasts out of the freezer and put them in the fridge to thaw about 10 days ago, and forgot them. They're in a vacuum sealed package. Safe or not safe?

 

Don't ask. Eat it.

My immune system is a beast, so I usually just use the "sniff test." I'm very sensitive to off-flavors in poultry, so microbial safety is usually less of a practical issue for me than palatability. So if you're feeling frisky, I'd say give it a sniff and roll with it. But caveat eater. I probably wouldn't serve it to my grandmother or kid sister.
