Introduction to Environmental Monitoring Programs
Environmental monitoring programs (EMPs) are a proactive approach that operations may take to reduce microbial contamination events. EMPs are designed to assess the effectiveness of the hygiene and sanitation practices in a food environment and provide valuable information to avoid microbial contamination of food products. EMPs are specific to each operation and depend upon the food(s) that are handled, packed, and or processed; operation size; operation layout; among other factors. If EMPs are effective, operations will be alerted to possible pathogen harborage locations based on positive test results, and operations will be able to implement corrective actions to reduce contamination events. Corrective actions may include targeted cleaning and sanitation of locations/adjacent locations that test positive and implementation of new policies or practices to reduce cross-contamination (for example, new employee or equipment traffic patterns). This publication serves as an introductory guide.

Food Safety Modernization Act Produce Safety Rule: Soil Amendments
The Produce Safety Rule (PSR) is one of the seven major food safety regulations that are authorized by the Food Safety Modernization Act (FSMA). The PSR standards (subpart F) describe the minimum requirements for treated and untreated biological soil amendments of animal origin and human waste for reducing public health risk and the risk of contaminating covered produce. The PSR standards include requirements for determining if biological soil amendments of animal origin are treated or untreated and how to handle them. The standards also address the use of human waste, treatment of the biological soil amendments, application methods and intervals, and recordkeeping.

Sprout Safety
The condition in which sprouts are produced is ideal for the growth of the foodborne pathogens, and if proper food safety practices and handling are not followed, sprouts can harbor pathogens when the seeds are sprouted. Many outbreaks of foodborne illness associated with consumption of raw sprouts have been reported in recent years, mainly by E. coli and Salmonella.

Microbial Quality of Water Used in Potato Packinghouse Operations
Postharvest handling of potatoes on the Eastern Shore of Virginia (ESV) regularly includes the use of flumes, dump tanks, and spray washers. Water used in flumes and dump tanks is often re-circulated to conserve water and energy. Soil, plant matter, and disease-causing pathogens can potentially accumulate in water during bin dumping and flume recirculation.

On-Farm Readiness Review (OFRR): Preparing for FSMA’s Produce Safety Rule
In Virginia, the Virginia Department of Agriculture and Consumer Services (VDACS) is enforcing the Food Safety Modernization Act (FSMA) Produce Safety Rule. The FSMA Produce Safety Rule is a regulatory rule by the Food and Drug Administration (FDA) that sets the science-based minimum standards for the safe growing, harvesting, packing, and holding of fruits and vegetables (FDA, 2015). All covered farms are subject to inspection. To help prepare for the regulation, operations can choose to have an On-Farm Readiness Review (OFRR). The OFRR is a program designed specifically to help produce operations align their food safety practices with the FSMA Produce Safety Rule and prepare them for an inspection by VDACS. A fully trained VCE agent conducts the OFRR, lasts no longer than 2 hours, is 100% confidential, and is entirely free.

Demystifying Agricultural Production Water Testing under the FSMA Produce Safety Rule
Under the Food Safety Modernization Act (FSMA) Produce Safety Rule (PSR), agricultural water is defined as “water used in covered activities on covered produce where water is intended to, or is likely to, contact the harvestable portion of the crop”. Production water is agricultural water used during produce growing activities prior to harvesting. Examples of production water include irrigation, fertigation, spray applications, dust abatement, frost protection, among others. Remember production water has to meet the definition of agricultural water to be regulated under the FSMA PSR. This document will cover why to test your production water, what to test your production water for, how to sample your production water, and most importantly how to interpret your production water test results.

Guide to Identifying Food Safety Hazards in Greenhouse Systems
According to the United States Department of Agriculture 2012 Census of Agriculture, sales from greenhouse-grown food crops equaled around $800 million in the U.S. Crops grown included tomatoes, lettuce, cucumbers, peppers, and berries, with hydroponic production operations making up about 64% of the total production (cwt) (USDA Census of Agriculture, 2012). Demand for greenhouse-grown produce continues to increase, providing growers with unique opportunities to tap into this expanding market. Although greenhouse systems provide a more protected environment than field-grown systems, it is important to understand the unique food safety risks and possible sources of contamination when growing produce in these systems. Identifying food safety hazards are necessary to implementing practices that reduce the risk of contamination during the pre-plant, production, harvest, and post-harvest handling stages. Use the checklist below to guide you in asking important questions targeting possible risks at each of the greenhouse system stages.
