Forty-nine fresh goat’s milk samples produced by local farmers and sold in market for public consumption as well as raw goat milk in Johor, Malaysia were analysed for total plate count(TPC) , E. coli, Coliform, Brucella melitensis, Brucella abortus,Coxiella burnetii as well as aflatoxin M1 (AFM1) content, as measures for food safety. The mean counts per ml for TPC were 4.90 x 105, 6.50 x 105, 1.60 x 105 and 1.48 x 106 for pasteurised, unpasteurised and unknown (status of pasteurisation) milk sold in the market as well as the raw milk from milkcollection center (MCC), respectively. Among pasteurised samples, only one had TPC count higher than the permitted level whereas the rest were all within the permitted level. The mean counts per ml for E. coli were <1.00 x 102 for pasteurised and unknown milkwhereas 1.67 x 101 for unpasteurised and 1.18 x 102 for raw milk. The mean counts per ml for coliform were 9.53 x 103, 9.76 x103, 1.20 x 102 and 1.16 x 104 for pasteurised, unpasteurised, unknown milk and raw milk, respectively. Overall, no significantdifferences on the bacterial counts in both pasteurised and unpasteurised milk. All milk samples were negative of B. melitensis and B. abortus, but one unknown sample fromthe market and two raw samples from MCC were positive of C. burnetii through the ELISA test. The unknown sample from the market showed the presence of C. burnetii when further analysed microscopically. Meanwhile, no sample exceeded the permitted level of AFM1 in milk.

Recently, diagnostic cases of Mycoplasma screening from feline kept rising. In 2018, there were two cases in felines that were positively diagnosed as Mycoplasma co-infection in which one of the two cases was due to mycoplasmosis. Diagnosis of mycoplasmosis was based on isolation and identification using biochemical testing. Mycoplasma was successfully isolated from both cases. Based on the feline death case, the result indicated that Mycoplasma gateae was isolated from the blood-stained trachea sample. In contrast, none was isolated from the lung. As the infection was associated with other microorganisms, this case concluded that the cause of death of the cat was due to Parvovirus with secondary infection of Mycoplasma gateae.

A trial and pig performance data collection was conducted to evaluate the efficiency of Luodong Bio- Fermentation Treatment Technology with zero discharge effect in a pig close house system at Tanjung Sepat, Selangor. This trial was done to gather and monitor the pig growth performance and the pig acceptance of using the Loudong Bio-fermentation Waste Treatment Technology in close house enviroment. Growth performance of the pigs were monitored by an average daily gain, feed conversion ratio, behaviour and veterinary observations. Close house temperature, moisture measurement and
bedding sampling were also conducted.
