When expecting, the quick and easy appeal of a cold cut sandwich often comes with questions about its safety. Cold cuts, such as turkey, ham, or roast beef, carry a specific food safety risk.
Pregnant individuals must approach these ready-to-eat meats with caution. While a cold cut sandwich is convenient, the potential health risk it poses to an unborn baby means that consumption should only occur under specific, safety-focused conditions.
The Primary Concern: Listeria and Pregnancy
The main risk associated with eating cold deli meats is contamination with the bacterium Listeria monocytogenes. This organism causes an infection called Listeriosis, which is particularly dangerous during pregnancy. The changes in the immune system that occur during gestation mean that pregnant individuals are approximately ten times more likely to contract Listeriosis than the general healthy adult population.
The danger of this bacterium is compounded by its ability to multiply even in cold temperatures, including inside a refrigerator. Because deli meats are often stored and consumed cold, they represent a significant exposure pathway for the bacteria. The bacteria can contaminate the meat after it has been cooked, such as during slicing at a deli counter or packaging at a processing facility.
If a pregnant person contracts Listeriosis, the bacteria can cross the placenta and infect the fetus. While the parent may experience only mild, flu-like symptoms, the effects on the developing baby can be severe. Infection can lead to devastating outcomes, including miscarriage, stillbirth, or premature delivery. Babies who survive the infection may suffer from serious conditions like blood infections or meningitis.
Safe Preparation Methods for Deli Meats
The primary method for making deli meat safe to consume during pregnancy is to ensure it is heated to a temperature high enough to destroy the Listeria bacteria. Health authorities recommend heating all deli meats, including cold cuts, hot dogs, and sausages, until they reach an internal temperature of 165°F (74°C). This temperature must be reached throughout the meat.
This safety measure means that any cold cut sandwich must be prepared using meat that is steaming hot immediately before assembly. Heating the meat on a stovetop in a skillet or using a microwave are common methods. If using a microwave, it is important to check the meat in several places, as microwaves can sometimes heat food unevenly, leaving cold spots where bacteria may survive.
For those who crave the taste of a deli sandwich, the meat must be cooked, not just warmed, and then can be cooled slightly before being placed on bread. This precaution also extends to other items commonly found at the deli counter, such as pre-made deli salads or refrigerated pâtés.
Recognizing Symptoms and When to Contact a Doctor
Symptoms of Listeriosis can be subtle, often resembling a mild case of the flu. A pregnant person may experience fever, muscle aches, headache, or gastrointestinal issues like nausea and diarrhea. Because these symptoms are non-specific, they can easily be mistaken for a common cold or the usual discomforts of pregnancy.
A complicating factor is the infection’s long incubation period, which can range from a few days to up to 70 days after consuming contaminated food. This long window makes it difficult to immediately link the illness to a specific meal. The pregnant person may feel only mildly ill, yet the infection could still be affecting the fetus.
It is important to contact a healthcare provider immediately if these flu-like symptoms develop, especially after eating high-risk foods like cold cuts. Be sure to mention any recent consumption of unheated deli meats or other refrigerated, ready-to-eat items. Early diagnosis and treatment with antibiotics can often prevent the infection from spreading to the baby and reduce the chance of serious complications.
