July 13 to July 17 in Mexico was a week that swung wildly between the serious and the mildly absurd.

Fittingly, the week’s biggest bilateral dust-ups both involved, one way or another, potentially “deadly connections” between Mexico and the U.S. On Tuesday, DEA Administrator Terry Cole’s claimed at a Florida conference that the Mexican government and cartel networks are “one … [and] the same,” an assertion that Mexico’s Security Cabinet flatly rejected, calling the remarks baseless and unfounded.

Later in the week, Mexico’s Health Ministry issued a formal travel advisory warning citizens about a rapidly growing cross-border cyclosporiasis outbreak, the parasitic illness nicknamed the “explosive diarrhea bug” that U.S. health officials have traced to shredded iceberg lettuce served at Taco Bell locations in five states.

Awkwardly for Mexico, the lettuce in question was grown on a Mexican farm, prompting supplier Taylor Farms to pull all central Mexico-sourced iceberg lettuce from the U.S. market — a deadly connection of the gastrointestinal variety, if you will.

Mexico’s tourism sector, meanwhile, took a string of body blows. World Cup visitor counts came in far below the rosy projections officials had floated for months, a sargassum crisis prompted Sheinbaum to make an official visit to Tulum and beach destinations got the news that U.S. airlines would cut roughly one million seats this summer. To end the week, a magnitude 7.4 earthquake struck off the Chiapas coast Friday morning, briefly triggering a tsunami alert.

On a lighter, more hopeful note, bees in Campeche may soon gain legal rights before the Supreme Court. All in all, an interesting week to say the least — read on for the full rundown.

Bilateral tensions rise over ICE abuses

Mexico escalated its response to a string of migrant deaths in U.S. custody this week, with the Foreign Affairs Ministry filing criminal complaints with the U.S. Department of Justice and state attorneys general over the deaths of 17 Mexican nationals during ICE operations or in detention since the start of Trump’s second term.

Sheinbaum called the shooting death of Lorenzo Salgado Araujo in Houston “practically murder” and urged Mexican society to show solidarity with compatriots living in the United States. Days later, following the news of yet another death — a Mexican man struck by a vehicle while fleeing an ICE operation in Florida — Sheinbaum insisted that migration “should not be criminalized” and called for due process in any deportation proceedings.

US designates two more cartels as terrorist organizations

Amid all that friction, the U.S. Treasury formally designated the Juárez Cartel and Los Viagras as foreign terrorist organizations, bringing the total number of Mexican criminal groups with that label to eight. The designation lets the Treasury freeze the groups’ U.S. assets and bars Americans from doing business with them, adding another layer of pressure on Sheinbaum’s government even as it seeks continued security cooperation with Washington.

The Juárez Cartel is one of the oldest drug trafficking organizations in Mexico and primarily operates along the border with Texas by exercising control of the Ciudad Juárez-El Paso corridor, a critical crossing point.

Los Viagras mostly work in the western state of Michoacán, where, according to U.S. Treasury Secretary Scott Bessent, “criminal extortion is particularly prevalent in the lucrative agricultural sector and economy of Michoacán.”

Sheinbaum unveils anti-femicide bill

On Wednesday, Sheinbaum and her chief legal adviser, Luisa María Alcalde, presented a bill to standardize femicide prosecution nationwide, the General Law for the Prevention, Investigation, Punishment and Reparation of Damage for the Crime of Femicide.

It proposes 10 legally defined “reasons of gender” for the crime and uniform sentences of 50 to 70 years, with attempted femicide carrying up to 45 years and 19 aggravating circumstances able to lengthen punishments further. The president said the goal is “zero impunity” and an end to the practice, still common in some state prosecutors’ offices, of reclassifying violent deaths of women as suicides. Officials reported femicides declined 10.7% in the first half of 2026, though more than 6,400 women were killed for gender-related reasons between January 2019 and January 2026.

Inflation drops to 5-year low

Mexico’s annual headline inflation rate fell to 3.37% in June, down from 3.94% in May and its lowest level since December 2020, landing just 0.37 percentage points above Banxico’s 3% target after three consecutive months of decline.

Tomatoes alone dropped 39% month-over-month, helping pull the non-core index lower, even as core inflation held at a stickier 4.03%. MND CEO Travis Bembenek weighed in with a perspective on why Mexico’s inflation rate, now running below that of the United States, is such a big deal, arguing it could reshape how businesses, investors and everyday households on both sides of the border plan and spend in the months ahead.

Sargassum scares — one exaggerated, one very real

Not every seaweed panic is the real thing. Beachgoers on Nayarit’s Pacific coast were alarmed this week by piles of gelatinous brown algae washing ashore, but researchers from the Autonomous University of Nayarit confirmed it wasn’t sargassum but Hypnea, a naturally occurring macroalgae tied to seasonal shifts in ocean currents and temperature that poses no known health risk, unlike its foul-smelling Atlantic cousin.

The real thing, however, is very much a problem on the Caribbean coast: Sheinbaum toured Tulum and Cancún this week to address a genuine sargassum crisis that is dumping 9,000 tonnes of smelly seaweed on Quintana Roo’s beaches every day. The president outlined a strategy to intercept the algae at sea before it reaches shore and to promote projects that recycle the collected seaweed, part of a “Tulum Reborn” package of measures she unveiled at a Friday press conference held in the beleaguered beach town itself.

Foreign business ties strengthen

It was a busy week for international commerce and diplomacy.

• The U.S. agreed to a 512% jump in its sugar import quota from Mexico for the 2026-2027 cycle, allowing Mexican producers to export up to 1.15 million tonnes.
• Sheinbaum also welcomed Japanese business leaders to the National Palace, discussing the roughly 1,600 Japanese companies already generating 350,000 jobs in Mexico.
• Panamanian President José Raúl Mulino paid an official visit to Mexico City, with Sheinbaum pledging support for the Panama Canal’s neutrality protocol amid ongoing threats from President Trump to retake control of the waterway.

Baja California drama piles up

It was, to put it mildly, a rough week for Baja California. Leaked audio recordings suggested Gov. Marina del Pilar Ávila Olmeda discussed cooperating with people identifying themselves as FBI agents, apparently to avoid possible criminal charges and extradition.

The state government confirmed the audios’ authenticity even as the governor denied striking any formal deal, and the opposition National Action Party (PAN) demanded she take a leave of absence pending investigation. Separately, Morena councilor María de Jesús Quijada of Tecate survived an armed attack that killed her husband, a former security official. And in a case unrelated to the governor but very much part of the state’s turbulent week, former Gov. Ernesto Ruffo Appel was arrested in Ensenada on organized crime and fuel-smuggling charges. Ruffo, Mexico’s first opposition governor, elected in 1989, is accused of being the majority shareholder of a company tied to a seizure of more than 15 million liters of hydrocarbons smuggled from the U.S.

Chipotle arrives — but will it stay?

The U.S. fast-food chain opened its first restaurant in Mexico this week, choosing the upmarket Monterrey suburb of San Pedro Garza García, Nuevo León, citing the region’s economic strength. Predictably, the idea of a U.S. chain selling a Tex-Mex take on Mexican food inside Mexico itself provoked plenty of social media mockery — and sparked an in-house debate over whether Chipotle’s arrival is good or bad for the country.

Another accident on the Interoceanic Railroad

Less than seven months after a passenger derailment killed 14 people, another accident struck the same rail line this week. A freight train came off the tracks in Asunción Ixtaltepec, Oaxaca, though officials reported no injuries and said cargo service was barely interrupted. Sheinbaum downplayed the severity, saying the train “moved” rather than fully derailed, and that inspections were underway. Passenger service on the line remains suspended following December’s fatal crash.
