Is grocery store sushi safe during pregnancy?

What does the evidence say about grocery store sushi during pregnancy?

1. Pre-packed smoked salmon sold at retail carried Listeria monocytogenes in 21.6 percent of 171 samples, and the same organism turned up in 44.1 percent of salad bar seafood ingredients. 1
2. Smoked, processed and ready-to-eat foods are among the categories most often implicated in listeriosis during pregnancy, and pregnant people are 10 to 20 times more likely to be affected than the general population. 2
3. Freezing is what handles the parasite side of raw fish, and testing shows the fish core must reach and hold minus 20°C for at least 24 hours, with the clock starting only once the core is that cold. 3
4. Rapidly bringing fish to a core temperature of minus 35°C eliminated all Anisakis larvae in testing, which is the faster commercial alternative to the 24-hour hold. 3
5. Chilled ready-to-eat food should be held below 4°C (39.2°F), and anything sitting between 4°C and 60°C for over two hours is no longer considered safe. 4

Is grocery store sushi safe in each trimester?

• First trimester. Sushi cravings and sushi aversions both turn up early, sometimes in the same week. If you want it, a cooked roll from the case is a reasonable option. What separates a good pack from a bad one is how long it has been sitting, not which store it came from.
• Second trimester. Grocery sushi becomes a regular lunch for a lot of people around now. The habit that matters is checking the pack time or date and taking the newest one rather than the one at the front. A pack made this morning and a pack made yesterday are genuinely different products.
• Third trimester. Buying two packs to save one for tomorrow is the thing to stop doing. A ready-to-eat chilled food gets riskier with each extra day, and late pregnancy is when listeriosis is most commonly reported. Buy what you will eat that day.
