I didn’t realise fairly how a lot I liked bacon, pancetta, chorizo and ham till the World Well being Group added processed meats to its listing of carcinogens in 2015. These salty, chewy pancetta chunks that ship a mushroom risotto stratospheric – if I can resist scoffing the lot earlier than the rice is cooked. The crumbly grain of Christmas ham carved off the bone. Translucent chorizo slices on vacation with a sip of purple wine, or fried with potatoes, coating them with purple umami oil. I’m that disgusting one who dips her fingers within the pan after cooking bacon, to savour the salty melted fats.

Maybe the well being dangers aren’t as scary as they sound so long as you’re not consuming the stuff day by day. However lots are. Britain is a nation of bacon bap breakfasters, with ham sandwiches a lunchbox staple. We serve these meals in our hospitals and our colleges, and as soon as I’d learn the most cancers information I couldn’t unknow it. I went from considering of charcuterie as conventional and pure – the stuff of bustling Saturday farmers’ markets – to shunning it as poisonous. As soon as I began checking the components, I noticed that even the farmers’ market stuff contained nitrates and/or nitrites. When meat with these components is cooked and eaten, carcinogenic N-nitroso compounds (NOCs) corresponding to nitrosamine are fashioned.

Even unprocessed purple meat (which incorporates pork) incorporates heme iron, which is concerned within the formation of NOCs. That is why the World Most cancers Analysis Fund recommends not more than three parts of purple meat every week – however, with regards to processed meat, “very little, if any”.

The components that make processed meats a lot worse are the artificial compound sodium nitrite (E250), together with sodium nitrate (E251) and potassium nitrate (E252). The latter two are each naturally occurring minerals – though they are often industrially synthesised – and have been utilized in meat curing for hundreds of years, to provide it color and defend it from lethal micro organism. Different micro organism, in the course of the curing course of or in our mouths once we chew the meat, convert the nitrates into nitrites – which is why, collectively, these components are sometimes referred to easily as nitrates or nitrites.

Even earlier than the WHO’s announcement, I used to be on board with the thought of lowering meat consumption for the sake of the planet. However I used to be removed from being a vegetarian. So I started to search for nitrate-free pork merchandise. That quest led me to a web based vendor having a stab at an additive-free ham, but it surely arrived gray, overly salty and distinctly unham-like. I used to be bitterly disillusioned. My accomplice tried River Cottage’s conventional dry-cure bacon recipe – utilizing salt and sugar – however the end result was too candy for my tastes, and a really completely different animal from standard British wet-cure bacon.

In 2022, the stakes rose. March noticed a bunch of cross-party MPs and eminent scientists writing to the federal government, urging a phasing out of nitrates. They argued that the components have been linked to the event of breast, prostate and bowel most cancers. What’s extra, meals know-how had caught up, they stated, and nitrates have been not wanted to make the meats look and style how shoppers count on – the period of gray nitrate-free ham was doubtlessly over.

In July 2022, France introduced it might be phasing out nitrates, and in December, analysis led by Chris Elliott, professor of organic sciences at Queen’s College, Belfast, demonstrated that mice consumed Herta frankfurters (freeze-dried and made into feed pellets) developed 82% extra tumours within the colon than these given a balanced rodent feed. At this time Elliott and his colleagues are campaigning for colleges and hospitals to cease feeding nitrates to youngsters and sufferers.

The WHO lists processed meat as a “known human carcinogen” together with smoking, alcohol and asbestos, however clearly these substances don’t all carry the identical danger. Smoking is the most important explanation for lung most cancers, which results in 35,000 UK deaths per 12 months. Alcohol is linked to seven sorts of most cancers, and comes with different well being dangers corresponding to coronary heart and liver illness, together with critical accidents. However, Denis Corpet, professor of meals security and human vitamin in Toulouse, says he by no means buys so-called nitro-meats. He used to pack charcuterie when he hiked up mountains, however now, he says, “I don’t buy it because we’ve learned so much.” Not that an occasional slice of ham as a part of a wholesome diversified eating regimen is that dangerous, he says, if it’s something like the normal plant-heavy eating regimen of Mediterranean peasants who “couldn’t afford meat very often”. His personal analysis has discovered that consuming calcium alongside your processed meat can block the carcinogenicity – though this hasn’t been demonstrated in giant cohorts but, so necessary cheese and ham mixtures is nowhere close to the official-medical-advice stage.

Within the meantime, British grocery store choices stay disappointingly nitrate-heavy. Most large shops do now provide an own-brand nitrate-free bacon. In my native I may discover one ring of nitrite-free chorizo, Unearthed’s prosciutto and serrano hams, and Finnebrogue Bare’s nitrate-free bacon and ham. Finnebrogue Bare’s bacon is among the many most costly per kilo. And that’s largely it, amongst cabinets upon cabinets of nitrates.

France is somewhat additional forward, says Corpet: “I would say a quarter are nitrate-free now,” and they’re solely “a little more expensive”.

It was Finnebrogue Bare that first demonstrated within the UK in 2018 that nitrate-free bacon butties have been potential. Primarily based in Northern Eire, the corporate began out making sausages for M&S, however the WHO’s 2015 report on processed meat gave them an thought. “We thought: we’ve got all this volume of pork; why don’t we step in and try and do this the ‘proper’ way?” says Jago Pearson, chief technique officer at Finnebrogue. In 2018, the corporate launched its Bare Bacon (now renamed Higher Bare) model and commenced producing M&S’s personal label nitrate-free bacon. Now it’s supplying Sainsbury’s, Tesco, Waitrose, Asda and Morrisons.

The key ingredient Finnebrogue provides as a substitute of nitrates is just “fruit and spice extracts” in response to Declan Ferguson, the agency’s analysis, improvement and technical director. It was developed by the Spanish meals know-how firm, Prosur and it’s also utilized in Waitrose Made with out Nitrite bacon, made by Pilgrim’s UK.

In line with Ferguson, the one purpose there needs to be any additive in any respect is to maintain the meat pink. A protein in meat known as myoglobin naturally turns purple after which brown because it oxidises, and the nitrates cease this taking place. If the bacon went grey-brown, he says, you couldn’t legally promote it as bacon. The Prosur additive is excessive in antioxidants, which, says Ferguson, additionally “stops that myoglobin going brown”. It doesn’t gradual the curing course of or have an effect on shelf life. “To the naked eye it looks like normal bacon,” he says, “but it actually isn’t the same pink as nitrate bacon and ham – it’s more red.”

Earlier than bacon was made industrially, he says, “it would have been done either through salting or salt plus drying”. Parma and Serrano ham are made equally: “The more traditional producers only use salt and drying.” Fermented merchandise like salami, for which microbes are important, can simply be made with out nitrates, too, he says. “Nitrates have been introduced over time to help speed up that process and to create something that looks pink and fresh,” says Ferguson.

After the carcinogen story broke in 2015, many within the meat trade claimed that nitrates protected charcuterie-lovers from contracting botulism, a uncommon however critical illness brought on by toxins produced by Clostridium botulinum micro organism. When Finnebrogue began making nitrate-free bacon and ham, it had to spend so much of money and time debunking this. “We’ve done ‘challenge-testing’, where we put the clostridium botulinum bugs in the bacon,” Ferguson says. “We tested whether it grew and we were able to prove that it didn’t.”

The Meals Requirements Company (FSA) says that nitrates and nitrites “have undergone a safety assessment prior to being authorised” and are “important preservatives which hinder the growth of harmful organisms, in particular the bacteria responsible for botulism”. Nevertheless, the company doesn’t insist on their use. “They are one of the ways manufacturers can choose to protect against growth of these harmful organisms,” says Adam Hardgrave, head of components on the FSA, “but other methods include using pH, water activity [essentially, how much water is available for the bugs to grow], salt, other food additives …”

“The other misconception,” says Ferguson, “was that nitrates contribute to flavour, when they don’t give you flavour compounds in themselves. We have won multiple awards for the flavour of our bacon.”

Within the US, there was a clampdown on bacon marketed as “uncured”, which has been spiked with celery or different vegetable extracts as a substitute of the E numbers. It might sound wholesome, but it surely’s not. Like many greens, celery is a supply of nitrate, and a concentrated extract can certainly stand in properly for the standard components. However the finish product nonetheless incorporates dangerous ranges of nitrates, and might now not be labelled as “uncured”, or “no nitrate or nitrite added”.

Prosur’s secret ingredient isn’t the one nitrate-free color enhancer available on the market. Ferguson says he’s conscious of producers in Spain, France and Germany utilizing related components, “or different ingredients to make something look red or pink through, say, cherry extracts or green tea”.

David Lindars, technical operations director of the British Meat Processors Affiliation, is surprisingly on board with a nitrate-free future, and says he’s discovered first rate nitrate-free salami at his native Tesco. He additionally says there are a whole lot of new nitrate-free trials occurring behind the scenes.

“They do take quite some time,” he says, “because you have to be absolutely certain there is going to be no risk to human health.” And the merchandise must match shopper expectation and shelf life. “It’s really expensive, too. You’re looking at circa £15,000 with one of the highly reputable labs.” Nonetheless, that’s small change in contrast with the price of new manufacturing traces: Finnebrogue spent £20m to get its up and operating.

Within the meantime, Lindars says, in conventionally cured meats, “there has been a big push over the past 18 months or so to reduce the level of nitrates from 150 parts per million, which is the maximum. Two retailers that I know of have reduced their standard product to 60 parts per million: Co-op and Waitrose.”

Whereas I’ve minimize my meat consumption, I can report that as an occasional deal with, Finnebrogue Bare bacon is simply pretty much as good as common sliced bacon and, sure, I nonetheless dip my fingers within the scorching fats. The Artysan Chorizo Riojano IGP ring is equally good, though I want there was a extra spicy model out there. Like most packaged ham, I discover Finnebrogue’s slices too slimy and grainless. There’s nonetheless a irritating lack of alternative. “There will be new nitrite-free stuff coming down the line later this year,” Pearson guarantees, although he received’t say what.

“Where developments tend to lag the most,” says Lindars, “is in food service,” ie takeaways and eating places. “Because your bacon roll – or whatever it may be – is cooked in the sandwich shop, the legislative requirements on displaying consumer information is very different.” Prospects, in flip, are sometimes much less rigorous in in search of dietary data when consuming out. “You tend to be in a different frame of mind,” says Lindars. “It’s kind of an impulse buy.”

However the sense is that change is within the works, largely as a result of, he says, “the consumer dictates, ultimately. You and me, we’re going to buy what we want and what we believe to be good for us.”
