Workshop on Veterinary Drug Analysis in Food and Feed by Veterinary Public Health Laboratory, Malaysia
On April 18th, 2017, Veterinary Public Health Laboratory (VPHL), Department of Veterinary Services Malaysia hosted a full-day workshop entitled Veterinary Drug Analysis in Food and Feed. This workshop was part of the activity of the Technical Working Group for Veterinary Drug Residues under the umbrella of National Food Analysis Committee. It was jointly organized with Waters Malaysia.
VPHL played host to participants from the regulatory agencies (National Food Quality and Safety Laboratory, National Public Health Laboratory), enforcement laboratory (Chemistry Department), Malaysian Agricultural Research and Development Institute (MARDI) and academia (MARA University of Technology, UiTM). VPHL took this opportunity to share recent development in sample preparation techniques to handle challenging matrices such as eggs and animal feeds for mass spectrometry analysis.
The opening session was delivered by Dr Rohana Abu Bakar, the Director of VPHL. The director mentioned that this workshop is a great opportunity for sharing experience between the participants and hope that the collaboration between the government and private company will continue to ensure safer food and feed by continuous expert sharing of testing methodology in the monitoring of veterinary drugs.
Dr. Jeremy giving lecture during theoretical session
The workshop started with a presentation by Dr Jeremy Shia from Waters USA entitled `Oasis PRiME HLB for veterinary drug analysis. Dr Jeremy touched on the importance of sample preparation, matrix interference removal and current industry trends. The workshop continued with practical sessions in the laboratory for sample preparation, instrumentation and data analysis.The workshop ran smoothly throughout both lecture and practical sessions. Participants were active, attentive and very enthusiastic about learning new information. By the end of the workshop, it was observed that the technical capacity and knowledge of all participants have been enhanced significantly.

Department of Veterinary Services operated as Federal and State Veterinary Services (Peninsular) and Veterinary Services of Sabah and Sarawak. DVS is Federal Government agency under the Ministry of Agriculture and Agro-Based Industries, Malaysia. The headquarters is located in Wilayah Persekutuan Putrajaya. The main function of DVS is to control, prevent and eradicate animal disease in order to promote the growth of livestock industry and to provide safe food for consumption. DVS is also responsible for ensuring the welfare of all animal.
There are two divisions involved in assurance of safe food, i.e. Division of Diagnostic and Quality Assurance (BDKK) in charge of the certification programme and laboratory function and Division of Biosecurity Management and SPS (BSPS) in charge of the food safety monitoring programme. BSPS is responsible for designing and engaging the national monitoring program of the safety and quality of livestock products as well as livestock based products. The objectives of the program are;
This monitoring program was emphasizes on testing for chemical residues (veterinary drug residues, pesticides, hormones and feed additives) and food microorganism (pathogen and indicator organisms) in livestock based products and livestock products throughout Malaysia.
Veterinary Public Health Laboratory (VPHL) under BDKK is responsible for conducting the tests as prescribe in the monitoring program. The main role of VPHL is to provide supportive services to the DVS, in particularly quality assurance program in ensuring the quality and safety of livestock products and livestock based product to the public. VPHL has been accredited with Malaysian Standard ISO/IEC 17025:2005 under the Malaysian Laboratory Accreditation Scheme (SAMM) since 2001, and has qualified with competence workforce to carry out the analytical procedures for which it has been accredited. The accreditation of VPHL is important to ensure confidence in the quality of the testing.
Sampling is conducted by DVS authorized officers and samples are taken from abattoirs and poultry processing plants under DVS supervisions. The national sampling plan is based on targeted samples whereby the quantities of the samples are calculated based on annual livestock productions and annual productions of livestock based products. Besides, VPHL also receives samples from private agencies and universities. The type of samples ranges from organs, meat and meat products, milk and milk products, eggs and egg products, and animal feeds.
The annual sampling plan for monitoring of imported livestock products which was previously conducted by DVS is continued by Malaysian Quarantine and Inspection Services (MAQIS). Normally samples such as meat or meat products are collected at the port of entry whether in the shipping ports or at the airports. The aim is to determine the prevalence rate of food quality safety parameters of concern; for instance, the food-borne pathogens or residues of veterinary drugs or pesticides meet the requirements of the relevant authority (DVS, MAQIS). The samples are sent to various governments’ laboratory including VPHL for safety and quality testing.
The reporting value for food microorganism and chemical residues are based on the value as stipulated in the Food Act 1983 (Food Regulations 1985). The results are reported to Veterinary Inspection Section as well as MAQIS (import) for further action to be taken. Follow up actions of violated cases are carried out accordingly for the success and effectiveness of the programme.
Animal feeds and animal feed additives by local producers and imported feeds are enforced under The Animal Feed Act 2009. This Act essentially regulates the quality of animal feeds by controlling the importation, manufacturer, sale and usage to ensure these animal feeds meet their nutrient requirements, not harmful or contaminated so that animals and animal products are safe for other uses.
Department of Veterinary Services, Malaysia (DVS)
