A crab cake is typically a patty made from cooked crab meat, breadcrumbs, and various binders, which is then fried, baked, or broiled. For expectant mothers, consuming crab cakes is generally considered acceptable. The safety of this popular seafood item depends entirely on ensuring it has been properly prepared and cooked to the correct temperature. This understanding allows pregnant individuals to enjoy crab cakes with confidence.
Safety Assessment of Crab Meat
The primary concern with seafood consumption during pregnancy often revolves around heavy metal contamination, particularly mercury. Crab meat is categorized among the shellfish with the lowest levels of mercury, making it a favorable choice. The risk of neurological harm to the developing fetus from methylmercury exposure is minimized when consuming low-mercury seafood like crab. This low contamination profile makes the meat an appealing option for a balanced diet.
Beyond its low mercury content, crab offers nutritional benefits that support a healthy pregnancy. It is a good source of lean protein, necessary for tissue growth and repair in both the mother and baby. Crab also provides micronutrients like zinc and Vitamin B12, supporting immune function and red blood cell formation. The FDA advises that pregnant individuals consume 8 to 12 ounces per week of low-mercury seafood, and crab is on the list of “Best Choices”.
The Hazards of Preparation and Undercooking
The potential health concern surrounding crab cakes does not stem from the crab meat itself but from how the final product is handled and cooked. Undercooking the cake creates an environment where foodborne pathogens can survive and multiply. Expectant mothers are about 10 times more likely to get listeriosis than other healthy adults due to changes in the immune system during pregnancy.
One risk is Listeria monocytogenes, a bacterium that can be present in seafood and is problematic during pregnancy. Listeriosis, the resulting infection, can lead to complications for the fetus, including miscarriage, stillbirth, or premature delivery. Cooking the crab cake thoroughly is the most effective way to eliminate this pathogen.
Another contaminant is Vibrio, bacteria naturally found in marine coastal waters that can concentrate in filter-feeding shellfish. While less common than Listeria in fully cooked products, improper handling of the crab meat before it is mixed into the cake can introduce this risk. Ensuring the raw ingredients are kept cold and the final product is fully heated mitigates this danger, as Vibrio is destroyed by cooking.
Many crab cake recipes use raw egg as a binding agent. If the crab cake is only browned on the outside and remains undercooked in the center, this raw egg can pose a risk of Salmonella infection. This highlights why the internal temperature is the most important factor for safety.
Guidelines for Safe Consumption
To safely enjoy crab cakes, expectant mothers must ensure the product reaches an internal temperature throughout the center. Seafood, including a cooked product like a crab cake, must reach an internal temperature of 145°F (63°C). This temperature is sufficient to kill common foodborne pathogens like Listeria and Salmonella.
The way to confirm this safe temperature is by using a food thermometer inserted into the thickest part of the cake. Relying solely on visual cues, such as a golden-brown exterior, is insufficient, as the center can remain undercooked. When dining out, inquire about the cooking method and request that the cake be cooked thoroughly, ensuring it is piping hot when served.
When preparing crab cakes at home, source the ingredients correctly. Only use crab meat that has been properly refrigerated or is labeled as pasteurized, which reduces the initial bacterial load. Avoid purchasing or consuming crab cakes that have been left unrefrigerated for an extended period, as bacteria can grow quickly between 40°F and 140°F.
The appearance and texture can offer clues about safety even without a thermometer. A fully cooked crab cake should be opaque and firm throughout the center, not translucent or wet. It should steam visibly when cut open, indicating it has reached a temperature safe for consumption.
