Getting Ready for Your Food Safety Audits
Scheduling USDA audits GAP, Harmonized or Harmonized Plus
Anyone who has not scheduled their audit needs to be aware of the documentation needed to be sent to the New Jersey Department of Agriculture prior to the audit. They will want to see a copy of your food safety plan, proof of your food safety training, any current water tests, training records of all personnel, ten days of supporting records (for example – cleaning and sanitizing equipment, monitoring for wildlife, approved supplier list, etc.), mock recall and a self-audit. Why do they want the records prior to the audit? It saves time on their end plus it will save the grower money by them spending less time on the farm.
The audits can be scheduled in two ways either call the NJDA office at 856-839-3388 or go to fvinspection@ag.nj.gov . There is a new request form so if you have an old form contact them for the new one. The request should be at least two weeks prior to the audit.
Need for multiple audits.
Crops may be grouped together on the initial request to be included in the audit. The audit needs to be scheduled so the auditor can see the distinct types of harvest activities. For an asparagus and tomatoes example, if the asparagus is being harvested during the initial audit while the tomatoes are growing but won’t be ready for harvest until a later date, the initial audit can cover both commodities but an unannounced audit would be used by the auditor to observe the harvest of the tomatoes. Also, the auditor will want to see all crops listed on the audit request form.
It is an option for the auditee to ask for commodities to be split on different audits. To certify two audits that occur at separate times for different commodities the auditee would need to let the auditor know the intention for two audits in the season. There would be a separate audit done, a certificate for each audit and a website posting for each audit. The certification dates would be separate for each audit done.
USDA Audit Rates Increasing October 1, 2024
Anyone who is getting a GAP, Harmonized or Harmonized Plus Audit through the New Jersey Department of Agriculture will see the rates increase in October. The basic hourly rate will increase from $155.00 to $163.00. Those that are getting a Global Food Safety Initiative (GFSI) certification will have an additional $250.00 for each audit.

AGENDA
4:00 – 6:00pm: Networking, meal, sign-in.
6:00 – 7:00pm: CEU Seminar: Tim Waller, Rutgers “Back to Basics – Pesticide Use”.
7:00 – 7:30pm: Questions and Discussion.
7:30 – 8:00pm: Door prizes and networking.
8:00pm: Adjourn.
Tim Waller will be presenting on “Back to Basics – Pesticide Use” which will be split into two sections. Section 1 will principally focus on reminders related to safe handling and application of pesticides. Specific topics will include reminders related to navigating labels, understanding PPE requirements, how REI and PHI can impact day-to-day activities, along with reminders related to handler training and the pesticide certification process will be discussed. We will also look at sprayer calibration and component selection as this can critically impact both the volume of materials used, and the ultimate efficacy of pest management via pesticide applications. Section 2 will focus on the decision-making process when determining where an application will be directed (air blast foliar, drench, pre/post potting granular etc.) and the label language that would allow that, along with specific pest examples to include at least 1 insect pest, 1 foliar disease, and1 root disease. Seminar is geared towards reminding growers of safe and effective use techniques in their operation.
Beat the Heat: Water and Sports Drinks for Hydration
Article By: The Rutgers Farm Health and Safety Working Group: Kate Brown, Michelle Infante-Casella, Stephen Komar and William Bamka
When it comes to hydration, the U.S. National Academies of Sciences, Engineering, and Medicine recommends an adequate daily fluid intake of about 15.5 cups (3.7 liters) of fluids a day for men and about 11.5 cups (2.7 liters) of fluids a day for women. Even with this guidance, the amount varies from person to person. Also, when temperatures are hotter and when workloads increase so should drinking water, to prevent dehydration and to help maintain the proper body temperature especially when sweating.
Regular intake of water throughout the day and during the evening, at recommended amounts may help prevent a person from becoming excessively thirsty and also prevent dehydration. The choice of drinking sports drinks that contain electrolytes may be considered when a person’s activities dramatically increase, when they excessively sweat, if they show signs of dehydration, and/or heat stress.
Most sports drinks are designed to replenish glucose, fluids, and electrolytes (sodium, potassium, magnesium, calcium) lost during strenuous exercise or heavy workloads. Sports drinks may contain carbohydrates in the form of sugar, usually glucose, high-fructose corn syrup, or sucrose. Some contain no sugar and are “sweetened” instead with low-calorie sweeteners. The amounts of sugar and electrolytes in sports drinks are intended to allow for quick hydration and absorption.
It is important to note, persons with diabetes should be mindful of not intaking amounts of sports drinks that are high in sugar that could raise blood sugar to unhealthy levels. Additionally, persons with high blood pressure should be mindful when drinking sports drinks that are high in sodium – most are. Persons who eat a healthy diet should have enough glucose and electrolytes to maintain their health, even during extra activities and with proper water intake. Some studies show drinking too many sports drinks, especially when not performing vigorous exercise, can increase the risk of overweight/obesity and other health issues such as type 2 diabetes, cardiovascular disease, gout and the risk of dental cavities.
Water is the best choice to stay hydrated and it is the responsibility of each individual person to be sure they drink enough water to maintain their proper health.
Avoiding Plectosporium blight in cucurbit fields
Plectosporium blight, also known as Microdochium blight or White speck, caused significant problems in some pumpkin fields the last few summers in New Jersey. The soil-borne fungal pathogen, although somewhat uncommon, can unexpectedly show up in some years and cause significant losses if left uncontrolled. The fungus survives in the soil on decaying plant debris where it can remain saprophytic by surviving off organic matter. Infection is characterized by the production of numerous light tan to “bleached” spindle shaped lesions that develop on vines and the undersides of infected leaves. Heavily infected vines and leaves can die leading to premature defoliation and subsequent sunscald on fruit. In cases of heavy disease pressure, spores that are produced on the bottom sides of leaves fall and infect the topsides of fruit laying beneath the canopy. Infection of stems leads to premature browning and drying reduce their longevity. Fruit infection, in most cases, remain mostly cosmetic in nature reducing fruit quality and may predispose fruit to other opportunistic fruit rots. Plectosporium blight often shows up during periods of prolonged wet weather where the soil remains wet for extended periods. “Hot spots” typically appear in fields before the pathogen is further spread by driving rains and wind.
From a production standpoint, stay away from fields with known history of the disease for as long as possible; provide adequate spacing between plants in- and between rows (i.e., avoid the overcrowding of plants); avoid over (pre-plant) fertilization that can lead to thick, dense canopies; avoid overhead irrigation (if possible); avoid planting in area of a field that remains heavily shaded where soils tend to dry too slow.
Controlling Plectosporium blight begins with regular scouting, recognizing symptoms, and identifying “hot spots” in the field. Protectant fungicides, such as chlorothalonil, as well as those used in weekly maintenance spray programs for cucurbit powdery mildew control will help control Plectosporium blight as long they applied on a weekly schedule with a high volume of water with thorough coverage. To help improve control on the undersides of leaves, a FRAC code 11 fungicide such as Quadris Top or Pristine, can be added to the tank mix. Remember, FRAC code 11 fungicides have translaminar activity and will move from the top surface of the leaf to the bottom. Growers who grow powdery mildew resistant varieties need to remember to scout their fields regularly even if cucurbit powdery mildew has not been detected on the farm or if regular maintenance sprays haven’t begun.

Recognizing Angular Leaf Spot in Cucurbits
Angular leaf spot, caused by the bacterium (Pseudomonas syringae pv. lachrymans), is common in New Jersey and the region. Although it often shows up during cooler, wet weather; it can show up almost anytime during the production season with favorable weather conditions for its development.

Angular leaf spot of pumpkin. Note leaf ‘shot holes’.
Angular leaf spot will first appear in ‘hot spots’ as, small water-soaked lesions which will expand until they reach a larger leaf vein resulting in the angular looking symptoms on leaves. Under heavy disease pressure, the bacteria will infect fruit causing small, water-soaked circular spots. In many cases once weather conditions become dry again, infected tissue in leaves will die and fall out leaving the characteristic ‘shot hole’ symptoms. Control of angular leaf spot begins scouting your fields, particularly in areas that may get shaded and remain wet after heavy rainfalls. Application of labeled rates of fixed copper plus mancozeb to help suppress the spread of the disease until hot, dry weather returns.
