Potatoes Start Out contaminated

Potato Source: Other growers and storages

Control Measures: All potatoes are inspected in the storage before we run them though our warehouse by Ernie Myers or Pam Dunning . Mtn. Valley truck drivers inspect the potatoes as they are loaded onto trucks hauling product to the packing shed.

Sanitizing Methods Control Measures: Wash Water will be treated with chlorine.

Belts and machinery will be disinfected with Hyamine and washing.

Records of these measures can be found in cleaning schedule of HACCP manual



Critical Control Point Control Measures
Potatoes are contaminated in Transit

Control Measures: Water used to wash potatoes is injected with ozone at wash point to disinfect any contamination.

Plant equipment is also washed every 2 weeks or more often if necessary and disinfected with Hyamine. Trucks are inspected and washed if necessary between changes in potato sources.



Potatoes are contaminated but it is not evident in a visual inspection Control Measures: Water used to wash potatoes is injected with ozone at wash point to disinfect any contamination.

Plant equipment is also washed every 2 weeks and disinfected with Hyamine. Documentation of cleaning is found in the cleaning section and is supervised by Robert Gonzales, Plant foreman. Also see master cleaning schedule for details.

 

 

Critical Control Point Control Measures
Workers contaminate potatoes during packing Control Measures: Workers are required to wash their hands with provided anti-bacterial soap while at work. Gloves are provided to workers that directly handle potatoes which are also washed.

Workers are not allowed to bring food or other contaminates into the work area. Plant equipment is also washed and disinfected with Hyamine every 2 weeks or more often if necessary.

 

Pest and Rodent Problems Control Measures: Traps are set around and outside the facility by Terminix of Alamosa - 589-4339. These traps are maintained monthly by Terminix.



A map of traps can be found in the pest section of this report.



Weekly checks are also performed by the Warehouse Ticket Recorder. Documentation of these checks can be found in the pests section of this report.

Food is only allowed in the break room eliminating a food source in the potato packing area.


Critical Control Point Control Measures
Outgoing trucks are contaminated Control Measures: Trucks are inspected before they are loaded. Documentation of this check is noted on the order form. If there is a problem trucks must be cleaned before they are loaded.

 

Foreign Objects
Food and other worker items Control Measures: Workers are not allowed to bring food and other items into the potato processing and packing area. They have a designated break area for these items.

 

Glass contaminating potatoes Control Measures: All light fixtures in the potato processing and packing areas are covered so if they break no glass will contaminate the product or pose a danger to employees.


Critical Control Point Control Measures
Rust contaminating potatoes Control Measures: Machinery at Mountain Valley produce is relatively new and shouldn't have this problem. In any case bi-monthly cleaning of equipment and periodic inspection of equipment by Robert Gonzales will eliminate this problem.
Bolts and other foreign objects falling off machinery Control Measures: Packing and processing equipment is very new and modern.

A catwalk throughout the packing shed allows thorough inspection of all machinery. Machinery is maintained by Robert Gonzales.



Machinery and flumes are inspected once a month at least and repaired and/or re-painted to prevent contamination of the product.

Grease contaminating potatoes Control Measures: Workers are trained to not over grease machinery.



Food quality grease is used in the packing shed.



Critical Control Point Control Measures
Quality Problems
Grade Problems Potato Source: Company Farm

Control Measures: Our potato crop is grown with the utmost attention to quality. The grower, Ernie Myers, supervises this process from planting to harvest and monitors the storages to maintain quality standards.



All potatoes shipped from the San Luis Valley, CO are under a mandatory marketing order. All potatoes packed in this shed are inspected by USDA inspectors and conform to USDA standards.



If a problem is detected during the running of a potato lot, we stop running it and make other plans for its use and destination



Potatoes are sorted on the line to remove unsatisfactory tubers.

Critical Control Point Control Measures
Grade Problems Potato Source: Other Farms

Control Measures: Before potatoes are brought to the shed they are inspected in storage or out of the field by either: Ernie Myers or Pam Dunning  for disease, quality and packout. Records of these inspections can be found in our records.

Mtn. Valley Truck Drivers inspect the potatoes as they are loaded onto trucks hauling product to the packing shed. If a problem shows up it will be investigated.



Critical Control Point Control Measures
Diseases Control Measures: Potatoes are inspected before they are run for diseases. If there is a serious problem they are not used.

Potatoes are sorted on the line to remove unsatisfactory tubers.



Ozone is injected into the wash water which will help eliminate some disease problems and help prevent spread of bacterial problems.



Potato processing and packing equipment is washed and disinfected with Hyamine bi-monthly to prevent buildup of disease levels on equipment.

Bruises Control Measures: Potato harvesting equipment is inspected during harvest for tuber bruising problems on the company farm fields and cooperating farm's fields.

Critical Control Point Control Measures
Temperature problems - Tubers too warm Control Measures: Potatoes are stored in modern storage facilities which maintain proper tuber temperature.

Mountain Valley produce has refrigeration units on some potato storages to cool down summer potatoes before they are shipped.



Packed product is stored in our cold rooms and shipped in refrigerated trailers.



Cold room temperature is monitored by a factory calibrated hobo temperature recorder that records temperature readings every hour continuously. These readings are downloaded and available on file.



Temperature recorders are calibrated by comparing them to a thermometer that has been calibrated with ice water. Documentation of this can be found in the HACCP manual in the misc. section.

Critical Control Point Control Measures
Sprouted Tubers Control Measures: Young properly stored tubers will not have a sprouting problem.



Later in the season Sprout-Nip is applied to the tubers during packing to assure no premature sprouting of tubers. Application of Sprout-Nip is supervised by Tim Miller.



Sprout-Nip is also applied in the potato storages commonly in the San Luis Valley around February to inhibit sprout formation.

Pesticide Problems
Pesticide residues Control Measures:

Random requests of grower pesticide records

Company Farm product is grown with strict adherence to pesticide labeling. Records of our pesticide use can be found in our records.



Before we run other farms potatoes we question the farmers on their pesticide use to assure to possible pesticide residues in their product.



In addition to asking outside growers about pesticide use, we randomly request records of pesticide use on potato fields that we are running the product. This policy is posted in our office and also available in the misc. Section of the HACCP manual.

Critical Control Point Control Measures
Pesticide contamination during processing and packing Control Measures: Pesticides and chemicals used in the packing shed are stored under supervision and locked in the shop.



Any pesticides and chemicals used in the packing shed is supervised by Tim Miller.



Information on the chemicals and pesticides used in the processing and packing of our potatoes can be found in the MSDS section of this report.

Miscellaneous Problems



Cull potatoes and organic trash creating a problem
Control Measures: All culls and organic trash from the packing shed are hauled away immediately to another site and composted.

Any remaining organic matter is disced and spread to under 2 inches so that it dries and eliminates any potential disease problems.

Miscellaneous problems from lack of warehouse cleaning Control Measure: See master cleaning schedule in cleaning section of HACCP manual
