Meat processing[edit]​

Potassium nitrate has been a common ingredient of salted meat since antiquity[38] or the Middle Ages.[39] The widespread adoption of nitrate use is more recent and is linked to the development of large-scale meat processing.[6] The use of potassium nitrate has been mostly discontinued because it gives slow and inconsistent results compared to sodium nitrite preparations such as "Prague powder" or pink "curing salt". Even so, potassium nitrate is still used in some food applications, such as salami, dry-cured ham, charcuterie, and (in some countries) in the brine used to make corned beef (sometimes together with sodium nitrite).[40] When used as a food additive in the European Union,[41] the compound is referred to as E252; it is also approved for use as a food additive in the United States[42] and Australia and New Zealand[43] (where it is listed under its INS number 252).[2]

Possible cancer risk[edit]​

Since October 2015, WHO classifies processed meat as Group 1 carcinogen (based on epidemiological studies, convincingly carcinogenic to humans).[44]

In April 2023 the French Court of Appeals of Limoges confirmed that food-watch NGO Yuka was legally legitimate in describing Potassium Nitrate E249 to E252 as a "cancer risk", and thus rejected an appeal by the French charcuterie industry against the organisation.[45]

Food preparation[edit]​

In West African cuisine, potassium nitrate (saltpetre) is widely used as a thickening agent in soups and stews such as okra soup[46] and isi ewu. It is also used to soften food and reduce cooking time when boiling beans and tough meat. Saltpetre is also an essential ingredient in making special porridges, such as kunun kanwa[47] literally translated from the Hausa language as "saltpetre porridge".

In the Shetland Islands (UK) it is used in the curing of mutton to make reestit mutton, a local delicacy.[48]

Well now I’m confused, it lists some pretty bad things in the data sheet if ingested?

One word - dose

 

[Hobie1dog]

Hmm is it giving an error on power up? Can you take a picture of the back with them plugged in?

No error on power up and when we use my wife's mouse and USB plug for her computer and plug it in, it works.

Ohhh ok I figured that as they were talking about dust it was a small dose, they should probably make that clear.

Or you should get more practice interpreting SDSs. This one lists the hazard effects - but not the severity. The NFPA code listed in the wikipedia article is 1-0-0. Which is the same as potassium chloride - salt substitute.

Well I’d never done it before, I just didn’t think that it sounded right. I stand corrected.

A full SDS has more detailed information than the link you provided. But remember, the audience for the information is chemists and first responders. Not the lay public.

Here's a full SDS. https://www.sigmaaldrich.com/US/en/sds/sigald/221295?userType=anonymous

You can see that the information is mostly repeated in your source - but the hazard emphasis is on it being on oxidizer. If you look down into the PPE and toxicity sections, you can see handling with thin nitrile gloves, and LD50 (lethal dose 50%) is higher than the testing ranges.

On the other hand, there's this:
https://www.atsdr.cdc.gov/csem/nitrate_2013/docs/nitrate_patient-education.pdf

Again, dose. And age; infants are especially susceptible. From the linked CDC paper:

For infants who are bottle-fed, nitrate poisoning can happen when nitrate contaminated drinking water is used to dilute formula... The inorganic nitrates found in contaminated well water are often overlooked as a source of nitrate exposure that can result in serious health effects in infants... Because the gastrointestinal system of infants is still developing after birth, they are at higher risk for serious health effects resulting from nitrate exposure.​

(Of course, the underdeveloped gastrointestinal system is combined with the low body weight to make matters even worse.)

I saw a case on what I think is one of the better medical mystery, stories of the ER type shows that was about exactly that. A mother, who breast fed her infant, was having serious surgery and would unable to feed the baby for a while, so bought some formula and prepared bottles. Grandma was in the surgery's waiting room holding the baby, and a passing nurse noticed that the baby's color was bad. She called an ER doctor, and they ended up having to put the baby in an oxygen tent while doing I don't remember what to combat the poisoning. By the time Mom came around, the baby was still in the pediatric care ward, but out of danger. One sharp-eyed nurse saved the baby's life; give that lady a medal!

But as for nitrate toxicity in general, while the baby was endangered, everyone else had been drinking from the same well for years and never had a problem.

Yesterday. Prepared my conversation with the courier company before calling (it helps me not swear).

Completely disarmed by very polite woman on the phone who promised she’d follow it up.

Tracking this morning shows onboard for delivery. Five days late.

Poured rain last night. Seriously poured. Three inches in two hours. Wet puppy as proof of the story… no banana for scale.

2 inches in 3 hours! I can't imagine what it would look like if we got 2 inches in 3 hours. But this is what .25" overnight does to our dry lake launch site. There was about 6" of water over everything.

A rat needs 2 grams or so, it’s pretty safe apparently.

I think that’s not a dry lake bed anymore… it’s just a lake.

Had to say goodbye to my wee mate, Fergal, after a very sudden and short illness. Organised for his private cremation today.
He joined our family within 3 weeks of us migrating to Australia, bringing us 11 years of joy after holding off for many years getting a dog.
RIP my wee mate.

Was that one of the leftovers from raining cats and dogs?

There is also a new lake in Death Valley. The Park Service had to stop people from kayaking on it. And starting Thursday we have rain in the forecast everyday through April 2nd.

Picked up some nails for my new framing nailgun. 50mm, 75mm, and 90mm.

Supercheap Auto had the nails on clearance, so I got a bargain. Lifetime supply I believe.

Will get some nails for the small gun later this week.

I had a doctors appointment in Vegas today. I saw a back specialist. I'm going to have some nerves ablated at L3,4 and 5. Again. I have had this done more times that I can remember. First time was in 2016 at The Mayo Clinic in Scottsdale. At that time I was taking 100mg of Oxycodone a day and still could barley walk. Their fix lasted years. The quack I had been seeing couldn't give me relief for more that a few months. Changed Doctors. I hope this new one is a keeper. And I got a haircut. We have been getting the house ready for the arrival of my two friends from Eugene. It's March Madness again. 12 hours a day in the Sports Book.

I watched five episodes of season 5 of Northern Exposure since I got up at 2:00 a.m.

Does that mean you'll be changing your business name and username?

 

[Charles_McG]

That’s not ‘Caution: Loose extension cords’?

 

[Hobie1dog]

Got my ears flushed out as I have to do each week due to wax buildup.

 

[OverTheTop]

My brother inlaw had bilateral (both sides) knee replacement surgery yesterday. He has even been for a short walk this morning .

 

[Cape Byron]

Does that mean you'll be changing your business name and username?

No, but the change will be reflected with a note in new instructions.

I’m proud to say I’ve met a number of elders from the Bundjalung nation. I even get called ‘Uncle’ sometimes.

 

[Hobie1dog]

Met with the respiratory supplier and he dropped off a new mask and hose and filters for my breathing machine

 

[Voyhager3]

I filled some forms, did some studying, and filled out a service request to get my AC fixed after decided to do a little funny and no longer work. This wouldn't be too much of a problem; however, instead of not blowing cold air and just blowing room-temp air, it's only blowing HOT air. It was a very rude awakening (quite literally) at five in the morning when my room was superheated to very hot. And the worst part is, I don't even have a fan to circulate the cold air from outside into the room to cool it off.

 

[teepot]

I picked up my friends from Eugene and came back to Pahrump and went straight to the Casino.
