Plush faces of characters, such as a bunny rabbit and a frog, are attached to the multi-coloured striped socks, introduced in the chain's stores at the end of last month.
But Migros warned on Tuesday that because these can easily be removed from the sock there exists a danger that infants can swallow a small bell that is integrated into the stuffed figures.
There is a risk that babies could suffocate if they swallowed the bell, the retailer said.
The socks (article number 8922.163) exist in different sizes in turquoise, pink and green, with different motifs that include a star as well as the rabbit and frog.
Migros advises customers to pull off the attachment containing the bell.
Alternatively, they can return the socks to the nearest store, where the purchase price of 6.90 francs will be reimbursed.
Migros also announced that it was recalling veal sausages that contain milk proteins that are not supposed to be in the product.
The sausages, which use the allergy label “Aha!”, in fact pose a health risk to people with a milk protein allergy.
A supplier to Migros noticed the presence of the milk protein in a spice used to make the sausages during an internal quality control check.
The affected Aha! Kalbsbratwurst sausages (product number 2302.103.520.10) are those with a “use by” date of January 1 2016 or later.
Customers can return the sausages to stores and get a refund for the 5.60-franc price.
Migros emphasized that the sausages are not a risk to people who are not allergic to milk proteins, including those who are lactose intolerant.
