The somatic cell count shall be not more than one million (1,000,000) cells per milliliter. The milk shall not contain drug residues.
The pour plate technique is the typical technique used to prepare plate count agars. Here, the inoculum is added to the molten agar before pouring the plate. The molten agar is cooled to about 45 degrees Celsius and is poured using a sterile method into a petri dish containing a specific diluted sample.
The plate count is linear for E. coli over the range of 30 to 300 CFU on a standard sized Petri dish. [4] Therefore, to ensure that a sample will yield CFU in this range requires dilution of the sample and plating of several dilutions.

An ultrasound showing an embryo measured to have a crown-rump length of 1.67 cm and estimated to have a gestational age of 8 weeks and 1 day. Crown-rump length (CRL) is the measurement of the length of human embryos and fetuses from the top of the head (crown) to the bottom of the buttocks (rump).
Once the umbilical cord is reached and the correct position of the needle is confirmed, the fetal blood is drawn. The needle is removed after all necessary samples are taken. The site of puncture is monitored after the procedure for bleeding. Also, if the fetus is viable, fetal heart rate is monitored post-procedure for one to two hours. [9]
