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 means of elevating cattle leads to different and scrumptious cuts that European shoppers 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 wish to know the place it got here from.”

Strict European Union meals laws, 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 related laws, is best — and desires 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 power apart, the administration is correct about one factor: European policymakers usually are not 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 group. American negotiators additionally need Europe to purchase extra American fuel and vans, to vary their consumption taxes and to weaken their digital laws.

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

However Europeans have their limits, and people embody 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 can be,” Olof Gill, a spokesman for the European Fee, the E.U. administrative arm, stated at a latest information convention. “That’s a pink 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 take care of Britain on Thursday, as an illustration, beef was a part of the settlement.

However based on 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.

In the case of the European Union, the USA 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 a wiggle room to decrease these well being and security requirements. And in terms of meat-related commerce restrictions extra broadly, there’s little or no. Rooster, as an illustration, faces comparatively excessive tariffs, and there’s 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 strong community of smaller household operations. The 27-nation bloc has about nine million farms, in contrast with about two million in the USA.

Subsidies and commerce restrictions assist to maintain Europe’s agricultural system intact. The European Union allocates an enormous chunk of its finances 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 fluctuate massively by product.

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

But it surely’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 progress stimulants, in contrast to in the USA, the place cattle are sometimes raised on giant 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 shortage of hormones leads to a much less homogenous product. “Each terroir has its style,” he explains, describing the distinctive “mouth really feel” of the West Flemish Crimson cow he raises on his farm on the Belgian coast.

However farming beef with out hormones is dearer. And American exporters have to stick to hormone limitations after they ship steaks, hamburgers or dairy merchandise to E.U. nations, which European farmers argue is simply 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 be president of La Coopération Agricole, a nationwide federation representing French agricultural cooperatives.

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

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

American scientists have known as the dangers of hormone use in cows minimal. And although E.U. officers and shoppers continuously 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 urged that such remedies usually are not a alternative for elevating a rooster in a means that makes it pathogen-free from the beginning. American scientists have concluded that the rinses do their job and usually are not dangerous to people.

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

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

“While you communicate 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 totally different, and people points are principally completely out of the palms of farmers.”

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

Farmer protests final yr loudly opposed extra beef imports from South American nations, partially over issues that the cows may be raised with a progress hormone. An Obama-era commerce deal died partially due to standard anger over “chlorine rooster” (“Chlorhünchen,” to derisive Germans.)

E.U. public opinion polling has urged that insurance policies that promote farming and farmers are highly regarded. In a 2020 ballot fielded in-person throughout the bloc, almost 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 worth positioned on the old style, small-scale means of doing issues, policymakers and farmers agreed. Mr. Dierendonck does purchase some American beef for patrons who ask for it — it’s simple 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 high quality wine. “For me, it’s about retaining traditions alive.”
