Mission
To provide expert state of the art analytical testing in support of food safety and security programs and consumer and agricultural interests in New York State.

Current expertise in food chemistry, food microbiology, pesticide residues, animal feed and fertilizer testing. The laboratory supports the regulatory programs of the Divisions of Food Safety and Inspection, Milk Control and Dairy Services, and Plant Industry by providing analytical testing of samples that are collected as part of scheduled regulatory or surveillance programs and in response to disease outbreak investigations, consumer complaints, and a variety of other food related investigations. Specialized analytical services are provided on a contract basis to universities and state and federal agencies within and outside of New York State. The laboratory is accredited to the ISO 17025 and AOAC ALAAC standards.

 

New Lab 2012

Major Responsibilities
Test all food and beverage samples collected by Department staff for specific health hazards, purity and/or accuracy of labeling. Collaborate with allied governmental agencies such as the Food and Drug Administration, the United States Department of Agriculture, the Environmental Protection Agency, the New York State Department of Health and the New York State Liquor Authority. The Food Laboratory has a cooperative agreement with USDA AMS to test produce and dairy products for pesticide residue in support of the Pesticide Data program. The laboratory is also the recipient of FDA grants to monitor hazards in animal feed and pet food, to develop a Rapid Response Team to respond to food borne illness and to expand the scope of accreditation to the ISO17025 international quality standard.

Food Microbiology
Approximately 1,100 food and dairy samples are tested/month. Target organisms include, total aerobic plate counts, total coliforms, E. coli, E. coli O157:H7 and other enterohemorrhagic E. coli, Salmonella enterica, Listeria monocytogenes, Campylobacter coli and jejuni, Bacillus cereus, Staphylococcus aureus, enterotoxins, and mycotoxins.

Food and Dairy Chemistry
Approximately 400 food and dairy samples are tested/month. Targets include specific allergens, undeclared preservatives, food colors, antibiotic residues, chemical contamination including pesticides and heavy metals, shelf stability, standard of identity and confirming nutritive content. Adequate space and expertise exist to perform a variety of analyses on a large number of samples. Current emphasis exists on allergen testing of food and antibiotic residues in food, particularly in support of the Departments Imported Food Initiative that specifically targets imported foods for selected hazards.

Animal Feed and Pet food analysis
Approximately 500 agricultural animal feed and pet food samples/year from New York state are tested to confirm label claims of nutritive content and declared and undeclared antimicrobials. The laboratory currently has grant funding in place from FDA to test for various hazards in animal feed and pet food. The analytes include toxic metals, mycotoxins, Salmonella, and Bovine Spongiform Encephalopathy (BSE).

Fertilizer and lime analysis
Approximately 160 fertilizer and lime samples/year are tested to confirm label claims of chemical content.

USDA Pesticide Data Program
A cooperative agreement initiated in 1991 between the Department and the USDA:AMS to test fruit, vegetables and public drinking water for pesticide residues. Similar contracts exist with nine other states – California, Colorado, Florida, Maryland, Michigan, Ohio, Texas, Washington and Wisconsin. Data are used by federal agencies for policymaking, regulatory and educational purposes. The program is dynamic and the targets for analyses frequently change as new pesticides are introduced to the market. The program has allowed the laboratory to become an international leader in the development and application of new technologies. The program has allowed the laboratory to expand its expertise in identifying and confirming low levels of pesticide residues, benefiting other programs in the Department and the laboratory through training opportunities and instrumentation.

The Pesticide Residue section tests an average of 150 food and dairy samples/month for contamination with over 200 different pesticides. 1738 samples were tested in 2012.

Research
Research aimed at improving methods of chemical and microbiological analyses are an ongoing effort in the Food Laboratory. Collaborative relationships with food safety staff in academia, industry and state and federal agencies exist providing a mechanism for the Food Laboratory to be involved in food safety and security research projects related to the ecology and epidemiology of food borne pathogens and specialized detection methods of biological and chemical hazards. The lab is currently improving methods for arsenic speciation in juice and rice, unallowed antibiotics in fish, and industrial dyes in several food matrixes. A recent project led to the identification of disallowed antibiotic residues in chicken jerky treats for dogs that resulted in a national product recall.

Food Safety and Security Programs
The New York State Department of Agriculture and Markets has an active program in food security. Three positions in the Food Laboratory, one food microbiologist and two food chemists, are dedicated to enhancing the laboratory’s ability to respond to food emergencies. Specific efforts include expansion of capacity, enhancements in rapid detection methods for biological and chemical hazards, and development of a communication system between allied laboratories in New York State’s Department of Health and the Food and Drug Administration.

The Food Emergency Response Network (FERN)
The Food Laboratory is a member of the FERN, a federally supported national network of state and federal laboratories with expertise in testing food for chemical, biological, and radiological hazards. The FERN provides local, regional, and national surveillance of hazards in food through information from national databases such as eLEXNET. The FERN provides a national infrastructure and organization to respond to food emergencies and provides extensive training opportunities to laboratory staff for rapid detection methods of specific pathogens and chemical hazards.  The FERN complements and enhances current state programs in food safety and security.

PulseNet
pulsenet logo, pfge fingerprint, woman using computer, woman using lab equipmentThe Food Laboratory is one of two agriculture sector public health laboratories that participates in PulseNet. PulseNet is a national network of federal, state and local public health and food regulatory agency laboratories coordinated by the Centers for Disease Control and Prevention (CDC). PulseNet laboratories perform standardized molecular subtyping (or “fingerprinting”) of foodborne disease-causing bacteria by pulsed-field gel electrophoresis (PFGE). PFGE can be used to distinguish between strains of organisms and PulseNet uses PFGE to characterize Escherichia coli O157:H7, Salmonella enterica, Shigella spp., Listeria monocytogenes and Campylobacter spp. at the DNA level. DNA “fingerprints,” or patterns, are submitted electronically to a dynamic database at the CDC. These databases are available on demand to participants allowing for rapid comparison of PFGE patterns and providing a valuable tool for detecting and investigating outbreaks of foodborne illness. Representatives of all foodborne pathogens isolated from food in the NY State Food Laboratory are submitted to the PulseNet database. For more information visit www.cdc.gov/pulsenet
