墨西哥城8月13日电——两起与泰勒农场相关的食源性疾病暴发事件,暴露了北美食品体系核心的一大弱点:美国正日益依赖墨西哥农产品行业,而监管机构却难以全力监管以保障消费者安全。
泰勒农场这家市值70亿美元的企业,为快餐连锁店、大型食品分销商和杂货商供货。本周,美国当局将一起导致数百人患病的沙门氏菌暴发事件与从墨西哥进口的辣椒联系起来后,该公司召回了含有辣椒的预制产品。这起事件紧随一起大型环孢子虫暴发事件之后,后者被追溯到泰勒农场从墨西哥进口的卷心莴苣,已造成超过6300人患病,2人死亡。

专家表示,这两起接连发生的事件重新引发了人们对美国食品药品监督管理局(FDA)监管进口食品能力的担忧。根据FDA的数据,2026年该局的雇员人数较2024年减少了22%,部分原因是唐纳德·特朗普重返白宫后进行了裁员。2025财年,FDA对外国食品工厂的检查数量下降了近13%,而进口食品规模却持续增长。
“毫无疑问,裁员对食品安全有害,”美国本土食品安全战略咨询公司创始人詹妮弗·麦金泰尔说道,“疫情暴发时对实际情况的监管力度减弱同样有害。”
FDA未回应置评请求。
对墨西哥的依赖
根据美国农业部的数据,1993年,也就是《北美自由贸易协定》生效的前一年,美国从墨西哥进口的农产品总额不到30亿美元。到2025年,这一数额增长了近1500%。
得克萨斯农工大学农业经济专家路易斯·里维拉表示,墨西哥目前占美国所有食品进口总额的20%以上。根据该大学的分析,2025年美国进口的新鲜农产品价值达161亿美元。
“我们不必等到应季才能全年享用农产品,”里维拉说,“拥有这些贸易伙伴对美国国内食品的可负担性至关重要。”
然而,那些让美国杂货店货架常年充盈的供应链,也时不时让消费者暴露在食源性疾病风险中。
过去二十年里,美国食品安全调查将多起暴发事件追溯到从墨西哥进口的水果和蔬菜,包括辣椒、甜瓜、香菜和绿叶蔬菜。
这些疫情引发了人们对分散的种植商、包装商和分销商网络中的灌溉水、卫生操作和食品安全控制措施的审视。FDA已在部分地区实施了保障措施,尽管墨西哥的出口商、种植商和加工商已经需要遵守美国的食品安全要求。
但专家表示,目前尚无统一的认证政策,要求所有墨西哥农产品供应商在出口到美国前证明其灌溉水安全。
墨西哥国家食品安全研究所的食品安全研究员克里斯托瓦尔·查伊德斯表示,农业用水是墨西哥新鲜农产品生产中一直存在的薄弱环节。
“在干旱期间,如果小农户找到了水源,他们可能会使用哪怕水质不佳的水,”他说,并补充道,食品企业最终应对其供应链的监管负责。
进口警报
泰勒农场暂时关闭了被美国官员认定为环孢子虫暴发源头的瓜纳华托加工厂。
该公司在一份声明中表示,其水源已针对粪便指示菌进行了检测。
“在任何出现食品安全担忧的情况下,我们都与监管机构充分合作,在有必要的情况下采取纠正措施,”该公司说道。
正在持续的环孢子虫暴发事件并非首次与墨西哥的泰勒农场相关联。2013年,美国疾病控制与预防中心将爱荷华州和内布拉斯加州与餐厅相关的疾病暴发事件,追溯到瓜纳华托州泰勒农场生产的袋装沙拉混合物。
历史上,FDA会在出现疾病暴发事件后,对特定产品和地区实施进口警报。
那些证明符合额外安全、溯源、审计和检测要求的企业,有资格进入该局所谓的“绿色名单”,无需提前接受检查即可避免货物在边境被扣留。然而,绿色名单系统并未广泛适用于墨西哥农业,而泰勒农场和墨西哥农产品相关的两起疫情,引发了人们对现有监管工具是否足够的质疑。
麦金泰尔表示,进口警报和绿色名单通常是在反复出现问题后才会启用,只是一种执法工具,而非标准要求。
“我不认为这是农产品安全的万全之策。它无法保证人们对这些操作有充分的了解和执行,”她说。

Taylor Farms outbreaks show limits of US ability to safeguard produce from Mexico

MEXICO CITY, Aug 13 – Two foodborne illness outbreaks linked to Taylor Farms have exposed a weakness at the heart of North America’s food system: the United States is increasingly relying on Mexico’s produce industry, and regulators are straining to oversee it to keep consumers safe.
Taylor Farms, the $7 billion company that supplies fast-food chains, major food distributors and grocers, recalled prepared products containing jalapenos this week after U.S. authorities linked a salmonella outbreak that has sickened several hundred to peppers imported from Mexico. It followed a major cyclosporiasis outbreak, traced to iceberg lettuce Taylor Farms imported from Mexico, that has made more than 6,300 people sick and caused two deaths.

The back-to-back incidents have revived concerns over the FDA’s ability to oversee imported food, experts say. The U.S. Food and Drug Administration’s employment fell by 22% in 2026 compared to 2024, according to agency data, in part due to workforce cuts since Donald Trump returned to the White House. Foreign food-facility inspections by the FDA fell by nearly 13% in fiscal 2025, while imports have continued to rise.
“Without question, the cuts are harmful to food safety,” said Jennifer McEntire, founder of the U.S.-based Food Safety Strategy consultancy, as is “having decreased oversight to what’s actually happening as outbreaks occur.”
The FDA did not respond to a request for comment.
RELIANCE ON MEXICO
The U.S. imported less than $3 billion in agricultural products from Mexico in 1993, the year before the North American Free Trade Agreement took effect, according to U.S. Department of Agriculture data. That level has increased by nearly 1,500% through 2025.
Mexico now accounts for more than 20% of all U.S. food imports, according to Luis Ribera, an agricultural economy expert at Texas A&M University. The U.S. imported $16.1 billion in fresh produce in 2025, according to a university analysis.
“We don’t have to wait for products to be in season for us to consume it year-round,” said Ribera. “Having those partners is very important for the affordability of food here in the U.S.”
Yet the same supply chains that keep U.S. grocery shelves stocked have also periodically exposed consumers to foodborne illness.
U.S. food safety investigations over the last two decades have traced outbreaks to imported Mexican fruit and vegetables, including peppers, cantaloupes, cilantro and leafy greens.
The outbreaks have prompted scrutiny of irrigation water, sanitation practices and food-safety controls across the fragmented networks of growers, packers and distributors. The FDA has imposed safeguards in some regions, though those exporters, growers and processors in Mexico are already subject to U.S. food-safety requirements.
However, there is no uniform certification policy requiring all Mexican produce suppliers to demonstrate their irrigation water is safe before exporting to the U.S., experts said.
Cristobal Chaidez, a food-safety researcher at Mexico’s National Laboratory for Research in Food Safety, said agricultural water is a persistent vulnerability in fresh produce production in Mexico.
“During a drought, if a small farmer finds a water source, they might use it even if it’s poor quality,” he said, adding that food companies ultimately bear responsibility for policing their supply chains.
IMPORT ALERTS
Taylor Farms temporarily shut down the Guanajuato processing facility that U.S. officials traced to the cyclosporiasis outbreak.
In a statement, the company said that its water sources are tested for fecal indicator organisms.
“We have cooperated fully with regulators in any instance where food safety concerns were raised, taking corrective action where warranted,” the company said.
The ongoing outbreak of cyclosporiasis was not the first linked to Taylor Farms in Mexico. In 2013, the U.S. Centers for Disease Control and Prevention
linked restaurant-associated illnesses in Iowa and Nebraska to a bagged salad mix from Taylor Farms in Guanajuato.
Historically, the FDA has responded to illness outbreaks by placing particular products and regions under import alerts.
Firms that demonstrate compliance with additional safety, tracing, audit and testing requirements may qualify for the agency’s so-called green list and avoid being held at the border without needing inspection first. Yet, the green list system does not apply broadly across Mexican agriculture, and the twin outbreaks involving Taylor Farms and Mexican produce have prompted questions about whether existing oversight tools are sufficient.
McEntire said import alerts and green lists are generally deployed after recurring problems emerge, and serve as one enforcement tool rather than a standard requirement.
“I don’t think that it is the be-all and end-all to produce safety. It doesn’t guarantee that there’s still thorough understanding and execution of these practices,” she said.
