A PROCESS FOR DETECTING STAPHYLOCOCCI-ENTERTOXIN IN FOODSTUFFS WHICH COMPRISES PREPARING EJACULATED SPERM OF MALE AMPHIBIANS BY TREATING THE AMPHIBIANS WITH 3 TO 5 MILLITERS OF 10 INTERNATIONAL UNITS OF PITUITARY GLAND GONADOTROPIN OR FOLLICLE STIMULATING HORMONE, ALLOWING THE SPERM TO REMAIN IN THE CLOACA OF THE AMPHIBIAN FOR AN HOUR, THEN WITHDRAWING THE SPERM AND DETERMINING THE PERCENTAGE OF MOBILE SPERMOTOZOA BY MICROSCOPIC OBSERVATION, MIXING A DETERMINED AMOUNT OF THE SPERM WITH AN EQUAL AMOUNT OF THE PURIFIED EXTRACT OF THE FOODSTUFFS TO BE EXAMINED AFTER HAVING HEATED THE FOODSTUFFS FOR 30 TO 60 MINUTES TO A TEMPERATURE IN THE RANGE OF 56*C. TO 85*C., DETERMINING THE DECREASE IN MOBILITY IN THE SPERMATOZOA WITHIN 10 SECONDS TO 20 MINUTES AND CALCULATING BY COMPARISON WITH THE ORIGINAL MOBILITY OF THE SPERMATOZOA THE PRESENCE OF STAPHYLOCOCCI-ENTEROTOXIN PER WEIGHT UNIT OF FOODSTUFFS.
