Listeria fears yank imported cured pork jowl off American shelves

A shipment of imported dry-cured pork jowl has been pulled from stores and food-service kitchens in several states after a routine safety check found it contaminated with Listeria monocytogenes, the bacterium responsible for one of the deadliest foodborne illnesses tracked by federal regulators. The product in question, known by its Italian name guanciale, is a cured, ready-to-eat cut prized in dishes like carbonara and amatriciana, and it is typically eaten without further cooking.

Federal inspectors caught the contamination before any confirmed illnesses were linked to the product, but the ready-to-eat nature of cured guanciale is exactly what makes Listeria contamination especially concerning to food-safety officials.

How the contamination was discovered

According to the USDA’s Food Safety and Inspection Service, the problem surfaced during routine import reinspection testing, when a sample of the imported product tested positive for Listeria monocytogenes. The recall, announced September 6, 2026, covers about 1,513 pounds of ready-to-eat pork guanciale produced at Est. 1937L Bome SRL in Italy on May 21, 2026, and imported into the United States in July 2026. FSIS says there have been no confirmed reports of illness associated with the recalled product as of the announcement.

Identifying the recalled guanciale

The recalled product was packaged in various-weight cardboard cases containing two individually vacuum-sealed pieces labeled “PRIME LINE DISTRIBUTORS, INC. GUANCIALE PORK JOWL PRODUCT OF ITALY,” bearing the lot code “263311US” and a “best if use by” date of 05.16.27. Two companies handled distribution: Prime Line Distributors, of Fort Lauderdale, Florida, shipped product to foodservice and retail locations within Florida, while Ferrarini USA, of Hoboken, New Jersey, distributed product more broadly, reaching California, Florida, Idaho, Illinois, Michigan, New Jersey, New York and Texas, according to Food Safety News.

Why FSIS classified this a Class I recall

FSIS reserves its Class I designation, the most urgent of its three recall categories, for situations where consuming the product carries a reasonable probability of serious, adverse health consequences or death. Because guanciale is a ready-to-eat product, typically sliced and eaten with minimal or no additional cooking, any Listeria present in the finished product would not be reliably eliminated before consumption, unlike raw meat that a diner would customarily cook to a safe internal temperature. That distinction, ready-to-eat versus raw, is central to why regulators treat Listeria findings in cured or smoked deli-style meats with more urgency than they would treat the same bacterium in a raw cut destined for the stove or grill.

Who faces the greatest risk from Listeria

Listeria infection, known as listeriosis, disproportionately affects specific populations rather than posing a uniform risk across the general public. The Centers for Disease Control and Prevention reports that more than half of all Listeria infections occur in people 65 and older, whose immune systems have a harder time clearing the bacteria and who typically produce less stomach acid, a natural defense that helps destroy many pathogens before they reach the intestines. Pregnant women, newborns and people with weakened immune systems also face elevated risk; for a pregnant woman, a Listeria infection can lead to pregnancy loss, premature birth or a life-threatening infection in a newborn, even when the mother herself experiences only mild symptoms such as fever and fatigue.

What consumers and retailers are being told to do

FSIS is urging any foodservice operator, retailer or household in possession of the recalled guanciale not to serve or sell it, regardless of whether the specific package shows any sign of spoilage, since Listeria contamination is not something that can be detected by smell, taste or appearance. The agency’s guidance is to either discard the product or return it to the place of purchase. Because the recalled product reached both retail counters and foodservice supply chains across eight states, FSIS is relying on the standard combination of public notice and retailer-level withdrawal to reach the full population of affected product, rather than a single point-of-sale recall limited to one chain or region.

Cured, ready-to-eat meats like guanciale, prosciutto and salami occupy an unusual place in food-safety oversight because curing and aging are themselves the food-safety controls, rather than a subsequent cooking step. Salt content, moisture reduction and controlled aging time are all meant to make the finished product inhospitable to most pathogens, but Listeria monocytogenes is notably resilient: unlike many foodborne bacteria, it can survive and even slowly multiply at refrigerator temperatures, which is part of why contamination in a cured product that will never be cooked draws a faster and more serious regulatory response than a similar finding in a raw cut of meat. Import reinspection sampling, the process that caught this particular contamination, exists specifically to catch failures in that curing and aging control before a foreign-produced product reaches a retail counter or restaurant kitchen.

Federal health guidance has long advised pregnant women, older adults and people with weakened immune systems to avoid deli-style meats altogether unless the product is reheated until steaming hot immediately before eating, a precaution built around exactly the risk profile this recall illustrates: a ready-to-eat product that carries no additional cooking step between purchase and consumption. Because symptoms of listeriosis can take anywhere from a few days to several weeks to appear after exposure, tracing a specific illness back to a specific cured-meat purchase is often difficult even when a contaminated lot has already been identified, which is part of why FSIS moves to recall suspect product immediately after a positive test rather than waiting for illness reports to accumulate.
