Stop Adding Cancer-Causing Chemicals To Bacon, Experts Tell Meat Industry (theguardian.com) 302

The reputation of the meat industry will sink to that of big tobacco unless it removes cancer-causing chemicals from processed products such as bacon and ham, a coalition of experts and politicians in UK warn this week. From a report: Led by Professor Chris Elliott, the food scientist who ran the UK government's investigation into the horse-meat scandal, and Dr Aseem Malhotra, a cardiologist, the coalition claims there is a "consensus of scientific opinion" that the nitrites used to cure meats produce carcinogens called nitrosamines when ingested. It says there is evidence that consumption of processed meats containing these chemicals results in 6,600 bowel cancer cases every year in the UK -- four times the fatalities on British roads -- and is campaigning for the issue to be taken as seriously as sugar levels in food.

"Government action to remove nitrites from processed meats should not be far away," Malhotra said. "Nor can a day of reckoning for those who dispute the incontrovertible facts. The meat industry must act fast, act now -- or be condemned to a similar reputational blow to that dealt to tobacco." [...] In a statement issued today, the coalition warns "that not enough is being done to raise awareness of nitrites in our processed meat and their health risks, in stark contrast to warnings regularly issued regarding sugar and fattening foods."

    Not sure if this is breaking news.

    • I was taught this in second year Organic Chemistry...in 1978.

      We were told you needed two things: beer and meat pizza.
      The nitrites were in the meat in the pizza.
      The beer provided the amines.
      Combine the two and you get the nitrosamines.

      Pretty unforgettable lesson.

      BTW, it is not really surprising this is only coming out now. Chicken feed contained an arsenic compound...for forty years.

    Either that or lying about nitrate content. I've NEVER seen "nitrate free" meat that wasn't lying with fine print: "..except that which naturally occurs in celery powder" is the same thing as "contains no salt, except that which naturally occurs in seawater."

      Modern meat-processing is clean and cold enough that there is no longer any case for using sodium-nitrite to prevent botulism.

      The real reason for using nitrite is that it makes the meat products red -- making meat look like how consumers are used to.
      Meat without nitrite is more grey, which looks less appetising.

      IS there any alternative to nitrates/ites? My understanding is the alternative to nitrates is botulism.

      From Wikipedia: "While meat-preservation processes like curing were mainly developed in order to prevent disease and to increase food security, the advent of modern preservation methods mean that in most developed countries today curing is instead mainly practised for its cultural value and desirable impact on the texture and taste of food. For lesser-developed countries, curing remains a key process in the production, transport and availability of meat."

      Curing in the developed world is not needed for safe food. It is used purely for taste and aesthetics. Of course, this is obvious. The same cuts of meat are commonly eaten in non-cured forms (either with artificial nitrate of celery-based nitrate) with no fears of botulism or other illnesses.

      The big question is whether people are willing to eat gray hot dogs. Maybe we can swap out the nitrates with red food coloring ...

      I have eaten lots of "nitrate free" meat, it was and is venison from deer that we have taken. Some of the venison sausage from those same deer, curing salt (sodium nitrate) is added. It all depends on the recipe. If someone objects to the nitrates, just tell then that pink salt is added. They probably are thinking Himalayan salt when it is Pink curing salt #1 or #2.

    Because nitrites are a natural component of certain vegetables - mainly celery extract. If you ban nitrites, you ban celery and most green vegetables. If you ban artificial nitrites, processed meat packagers will simply use celery extract as a preservative. That's what the "nitrite-free bacon" products do - if you read their list of ingredients, you'll find celery extract listed prominently. Because the natural nitrites in it are used to preserve the cured meat in lieu of artificially produced nitrites. The only difference is the former can be labeled "celery extract" while the latter must be labeled as "nitrties."

    At some point you have to accept that lots of naturally-occurring substances can kill you. And stop going on witch hunts against things just because they have a scary name that you don't recognize even though you've been eating, breathing, or rolling around in it all your life.

    The only way I can see this working is like how we recommend how much fish you should eat because of the different amounts of mercury they contain. Come up with a list of the maximum amount of a food you should eat in a week due to the nitrites they contain. Bacon, hot dogs, celery, cabbage, carrots, spinach, beets, etc. And publish those as health advisories.

          So let's make this clear, having read that study. Cows were being fed rancid herring, which not only has higher nitrate levels, but also a variety of toxins produced by the meat going rancid. But it's the nitrates that caused liver cancer, and not the liver processing the high levels of toxins that were also present and in turn killing the liver. Especially since it showed that the liver had no problems processing the levels and simply passing it directly into the kidney's and intestines.

        When you use celery juice in natural cured bacon, you are not adding any nitrates. However when celery juice interacts with the meat over time,. it breaks down into a concentration of nitrates that is 4 times the legal limit of just adding nitrates. However since this is "naturally occurring" as part of celery, it's not banned or regulated.

      Agree with your general point, but this whole discussion seems to be a little confused about nitrates vs nitrites vs nitrosamines, so a quick chemistry overview for some clarity:

      Nitrates (most oxidized form) -> nitrites (two-electron reduction of nitrate. Outside of industrial processes only occurs biologically by the bacterial enzyme nitrate reductase) -> Nitrosamines (reaction of nitrites with secondary amines. Requires heat and/or acidic conditions. These are generally stable compounds.) -> Hydroxylated nitrosamines (Unstable intermediate formed by enzymatic processes that mostly occur in the liver) -> Nitronium cation (spontaneous breakdown of the hydroxylated nitrosamine. Cation is an alkylating agent that can modify DNA.) -> DNA damage -> DNA repair or cancer

      The basic gist here is to illustrate that there is clear mechanistic reasoning behind the notion that nitrates have a cancer risk associated with them. But it also illustrates that the transformation is complex and there are multiple ways for harm to be mitigated long before a cancer risk is ever truly a risk.

      For example,
          Sodium nitrite in food cooked at high temperature with high protein content -> skips step 1 and facilitates direct production of nitrosamines that get ingested and transformed in the liver
          Sodium nitrate plus antioxidants -> hinders production of both nitrites and nitrosamines -> lower risk of being transformed in the liver
          Nitrates in vegetables -> typically have low protein content and lots of antioxidants, so low risk of producing nitrites or nitrosamines
          Celery juice -> naturally occurring nitrates -> no intrinsic risk of being converted to nitrites, especially if antioxidants are also present
          Celery powder -> evaporated celery juice (same as above)
          Cultured celery powder -> celery juice that is treated with bacteria and then evaporated -> this causes the nitrates to be converted to nitrites (by the bacteria) and presents a direct path to nitrosamine production if used to treat high protein content foods (aka meats)
          Bacon -> depending on above may have varying levels of nitrites or nitrosamines present after cooking, but generally low levels overall -> likely a low cancer risk, but may present a higher risk depending on frequency of consumption and other dietary factors
          Celery, arugula, beets -> high in nitrates, but no nitrites or nitrosamines present, even when cooked in the presence of meats (ex: stews) -> low, probably non-existent, cancer risk
          Cigarette smoke -> high concentration of nitrosamines inhaled directly into the lungs -> the nitrosamines still have to make their way to the liver, but represents a moderately high risk of cancer, especially considering the often habitual and frequent nature of smoking

         

  • I wish more companies sold frozen bacon, it freezes really well and there's no need to add nitrates.
    • That would likely be frozen pork belly without any nitrates or nitrates. What do you think curing is? You can use just salt but it takes a lot longer.

      • They already sell uncured bacon, and I've frozen it myself for later use. It keeps more than long enough that the only benefit to buying it already frozen is that you don't have to spend the energy to do so at home. It would cost more to ship frozen, though, so you'd pay anyway.

        The bellies are smoked and then cured with only time, then sliced into "uncured" bacon.

        • No such thing as uncured bacon - that's just pork belly. It's a misnomer that the FDA forces on companies who sell meat cured with celery juice or other forms of nitrate that don't come directly from a mineral salt.
