Shellfish during pregnancy: can you eat them? All the rules for doing so safely.

Many expectant mothers wonder whether shellfish and shrimp can be eaten during pregnancy .
The answer is yes , as long as you follow some fundamental rules regarding product choice and cooking .

Shellfish are a valuable source of protein, iron, iodine, and omega-3s , but if not handled properly, they can contain bacteria or parasites that are dangerous during pregnancy.

1. Product choice: quality and freshness first and foremost

During pregnancy, food safety begins at the fish counter.
Always choose shellfish:

• Fresh , with a delicate smell and shiny shell

• Or frozen , from reliable brands and with legible labels

Instead, avoid:

• Raw, marinated, or undercooked shellfish (such as carpaccio or lemon prawns)

• Salted, cold-smoked, or unpasteurized products

💡 Rustilia Tip : If you buy thawed shellfish, cook it immediately and never refreeze it. The cold chain is essential to prevent contamination.

2. Safe cooking: the real secret to enjoying them without risks

Cooking is what makes shellfish safe during pregnancy.
Only high, uniform temperatures eliminate any harmful microorganisms such as Listeria or Salmonella .

Here are the most recommended cooking methods:

• Steamed (with steamer) → perfect for prawns and scampi: it maintains their nutritional properties and guarantees a constant temperature.

• In the air fryer → modern and lightweight alternative: cooks evenly at over 180°C without oil, reducing fat and bacterial risks.

• In the oven or in a non-stick pan → ideal for more flavourful dishes, with the addition of natural flavours such as lemon, parsley or ginger.

🍤 How to tell if shellfish are cooked through:

• The flesh becomes white and opaque , no longer translucent

• The shell takes on a bright red-orange color

• The interior is firm and compact

• Always wash hands, knives, and cutting boards after handling raw fish.

• Use separate utensils for fish and vegetables.

• Do not leave shellfish at room temperature.

• Eat dishes as soon as they are cooked , avoiding reheating them several times.

4. Nutritional benefits for mother and child

If chosen and cooked correctly, shellfish can be a valuable food:

• High-quality proteins → promote fetal growth

• Omega-3 (EPA and DHA) → help brain and visual development

• Iron and zinc → support the maternal and fetal immune system

One or two portions a week of well-cooked fish or shellfish are perfect for a balanced pregnancy diet.
