There is no doubt that the excellent preventive measure of 

 official inspection for trichinella has led to the avoidance of grave 

 disasters ; 'its introduction has not yet caused an entire cessation 

 of trichinosis in man, because inspection of pork is not obligatory 

 everywhere, so that human beings may become infected by un- 

 examined trichinous pigs from their own country or from abroad, 

 and also because an infection may occasionally escape notice. For 

 these reasons the meat imported into Berlin from abroad as free 

 from trichinae is examined again and not always in vain ; finally, 

 also, gross negligence may at times occur, or fateful errors may 

 be made. 



In addition private prophylaxis must riot be neglected, and its 

 chief aim should be directed to the suitable preparation of pork.
