Hendrik Dierendonck, a second-generation butcher who has change into, as he describes it, “world well-known in Belgium” for his curated native beef, thinks Europe’s manner of elevating cattle ends in different and scrumptious cuts that European customers prize.

“They need hormone-free, grass-fed,” Mr. Dierendonck defined just lately as he lower steaks at a bloody chopping block in his Michelin-starred restaurant, which backs onto the butchery his father began within the Nineteen Seventies. “They need to know the place it got here from.”

Strict European Union meals rules, together with a ban on hormones, govern Mr. Dierendonck’s work. And people guidelines may flip right into a trade-war sticking level. The Trump administration argues that American meat, produced with out comparable rules, is best — and needs Europe to purchase extra of it, and different American farm merchandise.

“They hate our beef as a result of our beef is gorgeous,” Howard Lutnick, the commerce secretary, stated in a televised interview last month. “And theirs is weak.”

Questions of magnificence and energy apart, the administration is correct about one factor: European policymakers will not be eager on permitting extra hormone-raised American steaks and burgers into the European Union.

Additional opening the European market to American farmers is only one ask on a laundry record of requests from the Trump crew. American negotiators additionally need Europe to purchase extra American fuel and vans, to vary their consumption taxes and to weaken their digital rules.

Commerce officers throughout the European Union are prepared to make many concessions to avert a painful and protracted commerce battle and to avert increased tariffs. They’ve provided to drop automobile tariffs to zero, to purchase extra fuel and to extend navy purchases. Negotiators have even suggested they may purchase extra of sure agricultural merchandise, like soybeans.

However Europeans have their limits, and people embrace America’s handled T-bones and acid-washed rooster breasts.

“E.U. requirements, significantly as they relate to meals, well being and security, are sacrosanct — that’s not a part of the negotiation, and by no means shall be,” Olof Gill, a spokesman for the European Fee, the E.U. administrative arm, stated at a latest information convention. “That’s a crimson line.”

It’s not clear how critical the Individuals are about pushing for farm merchandise like beef and rooster. However the matter has surfaced repeatedly. When U.S. officers unveiled a commerce cope with Britain on Thursday, as an example, beef was a part of the settlement.

However in response to Britain, the deal would merely make it cheaper for Individuals to export more hormone-free beef to the nation and wouldn’t weaken British well being and security guidelines, that are much like these within the E.U.

With regards to the European Union, america can already export a considerable amount of hormone-free beef with out dealing with tariffs, so an equal deal would do little to assist American farmers.

However diplomats and European officers have repeatedly insisted that there isn’t any wiggle room to decrease these well being and security requirements. And in the case of meat-related commerce restrictions extra broadly, there may be little or no. Hen, as an example, faces comparatively excessive tariffs, and there may be restricted urge for food to decrease these charges.

That’s as a result of Europe is protecting of each its meals tradition and its farms.

The place America tends to have huge agricultural companies, Europeans have maintained a extra sturdy community of smaller household operations. The 27-nation bloc has about nine million farms, in contrast with about two million in america.

Subsidies and commerce restrictions assist to maintain Europe’s agricultural system intact. The European Union allocates a giant chunk of its price range to supporting farmers, and a mixture of tariffs and quotas restrict competitors in delicate areas. E.U. tariffs on agricultural merchandise are round 11 percent general, based mostly on World Commerce Group estimates, although they differ vastly by product.

And the bloc may place increased tariffs on U.S. farm items if commerce negotiations fall by. Their record of merchandise that would face retaliatory levies, printed Thursday, contains beef and pork, together with many soy merchandise and bourbon.

Nevertheless it’s not simply tariffs limiting European imports of American meals. Strict well being and security requirements additionally preserve many overseas merchandise off European grocery cabinets.

Take beef. Mr. Dierendonck and different European farmers are banned from utilizing development stimulants, in contrast to in america, the place cattle are sometimes raised on massive feedlots with the usage of hormones. European security officers have concluded that they cannot rule out well being dangers for people from hormone-raised beef.

To Mr. Dierendonck, the principles additionally match European preferences. The dearth of hormones ends in a much less homogenous product. “Each terroir has its style,” he explains, describing the distinctive “mouth really feel” of the West Flemish Pink cow he raises on his farm on the Belgian coast.

However farming beef with out hormones is costlier. And American exporters have to stick to hormone limitations once they ship steaks, hamburgers or dairy merchandise to E.U. nations, which European farmers argue is barely truthful. In any other case, imports produced utilizing cheaper strategies may put European farmers out of enterprise.

“We can not settle for import merchandise that don’t meet our manufacturing requirements,” stated Dominique Chargé, a cattle farmer from the west of France who can also be president of La Coopération Agricole, a nationwide federation representing French agricultural cooperatives.

The result’s that america doesn’t promote a lot beef to Europe. It makes extra financial sense for U.S. farmers to promote into markets that permit hormone-raised cattle.

One frequent American grievance is that European well being requirements are extra about desire than precise well being.

American scientists have referred to as the dangers of hormone use in cows minimal. And although E.U. officers and customers steadily sneer at America’s “chlorinated chickens,” that rallying cry is a bit dated. American farmers have for years been utilizing a vinegar-like acid, and never chlorine, to rinse poultry and kill potential pathogens.

Some studies in Europe have advised that such therapies will not be a alternative for elevating a rooster in a manner that makes it pathogen-free from the beginning. American scientists have concluded that the rinses do their job and will not be dangerous to people.

“I don’t know that it’s actually concerning the science,” stated Dianna Bourassa, a microbiologist specializing in poultry at Auburn College. “In my microbiological opinion, there aren’t any well being implications.”

From the attitude of European farmers, although, whether or not the well being dangers are real is apart from the purpose. As long as European voters oppose chemical-treated rooster and hormone-treated beef, Europe’s farmers can not use these farming methods.

“If you converse to our farmers, it’s about equity,” defined Pieter Verhelst, a member of the chief board of a Belgian farmers’ union, Boerenbond. “The coverage framework we begin with is completely completely different, and people points are largely completely out of the palms of farmers.”

And European customers do appear to assist E.U. meals and farming guidelines.

Farmer protests final 12 months loudly opposed extra beef imports from South American nations, partly over considerations that the cows may be raised with a development hormone. An Obama-era commerce deal died partly because of well-liked anger over “chlorine rooster” (“Chlorhünchen,” to derisive Germans).

E.U. public opinion polling has advised that insurance policies that promote farming and farmers are very talked-about. In a 2020 ballot fielded in-person throughout the bloc, practically 90 % of Europeans agreed with the concept agricultural imports “ought to solely enter the E.U. if their manufacturing has complied with the E.U.’s environmental and animal welfare requirements.”

In Europe, together with at Mr. Dierendonck’s butchery and farm, there’s a price positioned on the old style, small-scale manner of doing issues, policymakers and farmers agreed. Mr. Dierendonck does purchase some American beef for purchasers who ask for it — it’s straightforward to cook dinner, he stated — however it’s a small a part of the enterprise.

“I like American beef very a lot, however I don’t prefer it an excessive amount of,” stated Mr. Dierendonck, explaining that to him, the meat his European suppliers present is different, like a superb wine. “For me, it’s about retaining traditions alive.”
