Case of the Week 738

This week's case was donated by Dr. Sheldon Campbell. The following object was noted in fresh sole.   

Interestingly, it was still alive!

 What parasite is present here? 

After carefully removing the worms, the sole was breaded in cornmeal and fried. Looks delicious! 
Would you eat this?

Answer to Case 738

Answer to the Parasite Case of the Week 738:  Probable anisakid larva in fresh fish (sole). This is a great reminder to cook your fish well before eating! Alternatively, freeze it for 7 days at -20 C before eating it raw. The final dish that Dr. Campbell created looked quite tasty (sans worms). 

Not just a few readers noted that they might have some hesitation in eating the final product. 😂

One reader commented that generous application of lemon juice to the thawed fish prior to cooking does a great job in removing any live worms (and may result in a mass exodus!) However, this is only a good solution if you like the taste of lemon 🍋.

Thanks again to Dr. Campbell for sharing this great case!
