Study Details Importance of Proper Temperatures in-Transit of Bagged Salads

By |

HPbaggedSaladA new study in the Journal of Food Protection’s February issue details that temperature abuse during commercial transport and retail sale of leafy greens negatively impacts both microbial safety and product quality. Consequently, the effect of fluctuating temperatures on Escherichia coli O157:H7 and Listeria monocytogenes growth in commercially-bagged salad greens was assessed during transport, retail storage, and display.

Thus, proper tempertures in-transit of bagged salads is very important.

Over a 16-month period, a series of time-temperature profiles for bagged salads were obtained from five transportation routes covering four geographic regions (432 profiles), as well as during retail storage (4,867 profiles) and display (3,799 profiles). Five different time-temperature profiles collected during 2 to 3 days of transport, 1 and 3 days of retail storage, and 3 days of retail display were then duplicated in a programmable incubator to assess E. coli O157:H7 and L. monocytogenes growth in commercial bags of romaine lettuce mix.

Microbial growth predictions  were validated by comparing the root mean square error (RMSE), bias, and the acceptable prediction zone between the laboratory growth data and model predictions. Simulations were performed to calculate the probability distribution of microbial growth from 8,122,127,472 scenarios during transport, cold room storage, and retail display.

Using inoculated bags of retail salad, E. coli O157:H7 and L. monocytogenes populations increased a maximum of 3.1 and 3.0 at retail storage. Both models yielded acceptable  and biases within the acceptable prediction zone for E. coli O157:H7.

Based on the simulation, both pathogens generally increased <2 log CFU/g during transport, storage, and display. However, retail storage duration can significantly impact pathogen growth. This large-scale U.S. study—the first using commercial time/temperature profiles to assess the microbial risk of leafy greens—should be useful in filling some of the data gaps in current risk assessments for leafy greens.

California Vegetable Shipments to Shift from Desert Areas; Avocado Loadings to Start Soon

By |

HP0312As we enter spring (officially March 20th) two things are certain regarding California vegetable shipmens.  Number one, a seasonal shift is coming relatively soon from the desert areas of California and Arizona to the Central San Joaquin Valley and the Salinas Valley.  Number two, there is going to be a gap in in some California produce shipments as the transition take place.

However, the question remains, just when is this shipping gap going to occur given the roller coast weather?

Cold crops are grown in Central California and the Salinas Valley and shipped the year round, and celery is a 12-month mainstay from Oxnard to Oceano.  However, items such as lettuce, broccoli and caulifower and some others shift growing areas during the year.  Cold weather in Salinas and the central valley knocked out some plants in their early stages and delayed plantings for about a week. About 90 to 100 days later, one would expect to see a gap,  It will happen, but when?  The guess in within the next couple of weeks.

California Avocado Shipments

Avocado shipments in 2013 crop came in around 500 million pounds, which is larger than normal volume. This year, volume should be around 300 million pounds, which is closer to average.

In 2014, shipments should start ramping up anytime and showing  sizable volume increase by late-April, before making a significant bump  in volume entering the summer months.

South Texas Produce Shipments are Increasing, with Some Help from Mexico

By |

HPtxOnionsShipments of Mexican sweet onions have been crossing the border into South Texas since mid February and are about three weeks or so later than normal, due to cold weather.  The Texas 1015 sweet onion crop in the Lower Rio Grand Valley is pretty much mirroring the Mexican onions and are behind schedule as well.

The Texas 1015 onion shipments should get underway within the next week and loadings should continue through May.  The Winter Garden District just south of San Antonio should start shipping sweet onions the first week of May and continue for about eight weeks.

A number of Mexican produce loads are crossing the border in South Texas ranging from carrots to strawberries, raspberries and roma tomatoes, among other items.

Some good news on the berry front is that TransFresh Corp. of Salinas, CA is working with a warehousing facility to provide its Techtrol CO2 process for Mexican berries crossing the border.  Bagged pallets of berries with the gassing process has been found to extend the shelf life and quality of berries.  It also reduces the chances of claims relating to the quality of berries.

Texas citrus shipments led by grapefruit and oranges are moving in steady volume from the Lower Rio Grande Valley.    About 100 loads of Texas oranges are being shipped weekly.

 

South Texas and Mexican produce – grossing about $5000 to New York City.

Southeastern Produce Shipping Areas to Become More Active This Spring

By |

HPmangosEveryone from produce truckers, to produce shippers and consumers a like can’t wait for spring given the wicked winter it’s been for much of the country.  The further into March we get the more volume and available loading opportunities will be, particularly with Southeastern produce shipments.

For example, Nicaraguan mangoes will be arriving in heaviest volume at South Florida ports, although some will be delivered to ports int he Northeast.

Florida blueberry shipments are just starting and will work their way northward in the state, before giving away to south Georgia blueberries in late April.  Strong volume is expected in part because of a late Easter (April 20) that is closer to Mother’s Day  (May 11).  Florida expects to ship 25 million pounds of “blues” this season, a 14 percent increase over a year ago.  Florida should peak the second and third weeks of April.

Georgia blueberry volume is also showing significant increases each year.

However, the big push comes in Florida in April with a host of mixed vegetable items reaching peak volume, particularly from southern and central parts of Florida.   Good volume should continue into May.

In Georgia, Vidalia sweet onion shipments will begin in light volume in late April.  Vidalia onion shipments could be down about 20 percent this year.  Central and southern Georgia are currently shipping moderate amounts of greens ranging from kale to collard.  Cucumbers, squash and other veggies will start maturing in April.

Florida mixed veggies, tomatoes and blueberries – grossing about $3100 to New York City.

Pairing Sauces, Spreads Liked by Kids, Increases Their Veggie Consumption, Study Says

By |

HPchuckyAccording to a new study, pairing flavored sauces and spreads liked by children with vegetables will get them to eat vegetables regularly.

Researchers from the Arizona State University interviewed 29 preschoolers on how they felt about 11 different vegetables including whether they liked it or disliked it or had never tried it. They measured the effectiveness of paring vegetables like cauliflower and Brussels sprouts with sweetened and unsweetened cream cheese.

The children were divided in three groups, the first group received the vegetable with unsweetened cream cheese, the second group with sweetened cream cheese and the third group received without any cream cheese. After one week, the participants were served these vegetables without any cream cheese. By the end of 15 days the researchers saw that children who were served vegetables along with cream cheese liked them significantly more than those who were served plain.

Less than a quarter of children liked Brussels sprouts without cream cheese whereas more than 72 percent of children liked the vegetable when served with cream cheese.

Majority of children in the U.S. do not eat the required amount of vegetables and children vegetable consumption is mainly hindered by Neophobia or a fear of something new- a condition that is typical among children between the ages 2 and 5 years. The authors said that this strategy of paring food with something that children and adults already know and like will induce them to consume more fruits and vegetables.

Elizabeth Capaldi-Phillips, study author and psychologist at Arizona State University said, “This has the potential to change the eating habits of children, including eating more vegetables, and this in turn will affect childhood obesity.”

According to a previous research, children need to try new foods at least eight to 10 ten times before they get used to its taste. But the new study got the children to like the vegetables only after seven trials.

Kanzi Apples from Washington State are one of Newer Apple Varieties

By |

KanziWashington-grown Kanzi brand apples are hitting retailers’ shelves on schedule, but production is limited.  However, within five years growers expect to be able to ship half a million cartons annually.

This year’s crop is has turned out very well and  doesn’t have the limitations the previous crop had in relation to a hail storm.  U.S. Growers are adding trees to increase production and meet strong market demand.  With the existing trees in the ground, and new plantings,  it is estimated that within five years, production will hit nearly 500,000 cartons.

Even with that expanding production, demand is great enough to require imported Kanzi apples to supplement the domestic program. The imports are expected in spring after the domestic apples have sold out. Kanzi was originally developed in the European market by Greenstar Kanzi Europe and has features from its parents, Gala and braeburn apple varieties.

Kanzi is fresh bi-colored apple with a unique sweet-sour flavor, now grown in the Washington state’s Wenatchee Valley.

Kanzi, as a name, does not perhaps have the same gravitas as the old heritage apple varieties – yet. Fortunately this is a pretty good apple so we can let the name grow on us. Kanzi has been developed and marketed by Greenstar Kanzi Europe (GKE) and first came on to the market in 2006.  Most supplies are from the Netherlands.

Produce Loads out of South Texas will Continue Showing Dramatic Increases

By |

HPmexHwyOpportunities for South Texas produce loads have been increasing over the years, but we haven’t seen nothin’ yet.  Produce truckers will have a lot more chances for Lower Rio Grande Valley produce loads than ever.

The reasons are two-fold.  First, more fruits and vegetables are being grown in Mexico, with many of the operations financed by U.S. produce companies.  Second, the completion of a Mexican highway between West Mexico’s Mazatln and Eastern Mexico’s Matamoros is reducing transit times to South Texas warehouses.  This also is cutting mileage and reducing freight costs for produce receivers thoughout the eastern half of the United States and Canada.

40,000-pound shipments of produce through Texas ports soared from 101,400 truckloads in 2007 to 159,482 truckloads in 2012, an increase of 58 percent.

Much of the produce used to go through Nogales, AZ and still does.  During this same period, Arizona ports had 112,328 truckloads in 2007 and increased to 130,022 by 2012, a 16 percent hike.  Additionally, at California ports there were 43,336 truckloads of produce crossing in 2007, which increased to 61,716 truckloads in 2012, up 42 percent.

Based on these trends of the last five years, a USDA study projects total Mexican imports at U.S. ports will hit 470,000 truckloads by 2020, an increase of 32 percent.  Texas ports are projected to grow to 260,000 truckloads, a 62 percent increase.

There are also plans by Mexico to make improvements to Mexican Federal Highway 40 connecting Mazatlan and Reynosa, the latter, which is located just across the river from McAllen and Pharr, TX.  This could increase Mexican produce imports to South Texas another 73 percent by 2020.

Texas produce and Mexican produce crossing into the Lower Rio Grande Valley – grossing about $3200 to Chicago.

California Desert Shipments will be Shifting Regions Around the MIddle of March

By |

HP0305aWhile much of the nation has been in an icy deep freeze, warmer than normal temperature in California have been excellerating growth of winter mixed vegetables on the West Coast and in the desert. The only problem is the lousy weather in so much of the country has stifled demand  for California vegetable shipments.

Veggies ranging from head lettuce to romaine and broccoli continuet to be shipped from California’s Imperial Valley and the Yuma district.  At times it isn’t the best quality, so make sure your receiver knows what kind of quality is being delivered to help reduce problems such as claims with deductions, or rejections.

You should expect a seasonal transition of desert vegetables to the Central San Joaquing Valley around the middle of March.

California strawberryshipments are coming out of Ventura County, Southern California and on a more limited basis from the Santa Maria District.  Rains last week in Southern California resulted in some damage, so keep an eye out of off grade are mariginally grade berries at least throught this week.

Coastal California blueberry shipments should start ramping up the last week of March with a peak in mid-April followed by the Central Valley through June.

Desert vegetables grossing – about $6000 to New York City.

Plenty of Potato Shipments Continue from the US and Canada

By |

HPspudsTotal potato loadings from U.S. shipping areas are expected to be down five percent for the 2013-14 shipping season, but spud haulers shouldn’t really notice a difference, since it is such a large crop.  A similar sitution exists with Canadian potato shipments.

Overall, the two countries combined means there are only three percent fewer potatoes for loading in North America.  The total is still a huge 501 million cwt. (per hundred weight).

Of that amount, about 398 million cwt. of  the potatoes will be shipped from U.S. production areas than the previous season, according to USDA statistics.  Canada will provide about 103 million cwt. of loads, two percent more than the previous year.

The U.S. had about 942,000 acres of potatoes planted, down from about 1 million acres the year before.  However, yields rose from 423 cwt to 427 cwt per acre.   Acreage also was down in Canada but yields were up significantly, rising from 274 cwt to 292 cwt per acre.

Here’s a glimpse at a few of the major potato shipping states.

Idaho Potato Shipments –  The state ships a lot of spuds by rail, but trucks still transport the majority of the loads.  Most pick ups orginate from the Upper Valley and the Twin Falls – Burley District.  Idaho is averaging around 1,650 truckload equivalents of potatoes being loaded each week.

You should gross about $4350 to Atlanta.

Colorado Potato Shipments – The San Luis Valley is averaging nearly 700 truck loads of potatoes per week.

You should gross about $4100 to New York City.

Wisconsin Potato Shipments – Most loads are originating from shippers within a 50 mile radius or so of Stevens Point in the Central part of the state.

You should gross around  $1400 to Cleveland.

Washington Potato Shipments

Spud loadings are originating out of the Columbia Basin and just across the state line in Oregon’s Umatilla Basin.  There’s about 325 loads of potatoes a week soming out of here.  They are also shipping even more onions than spuds – about 800 loads a week.

You should gross about $3000 to Chicago.

Big Mexican Volume is Crossing US Border; Use Caution with Consigned Produce Loads

By |

HPnogalesMexician produce is causing a flood of volume crossing the U.S.  border.  In fact it is so much product, combined with lousy winter weather spanning much of the US, it is killing demand (in other words consumers aren’t buying as much and retailers aren’t ordering as much).

A main concern in this situation is some shippers will do just about anything to sell their product before it rots.  That can mean rolling loads of produce unsold — in other words on consignment.  This too often results produce truckers having to change destinations, facing more drops than originally told, etc.

This makes it especially important you are dealing with good, honest shippers, truck brokers, receivers – to make sure you are getting fairly compensated for any additional mileage, drops, etc.

West Mexico vegetables came on strong in February as delayed volumes of tomatoes, bell peppers and cucumbers finally started crossing at Nogales, AZ and in South Texas.  Shippers, meanwhile, were facing poor demand thanks to a series of winter storms in the Midwest and Northeast.

One example is peak supplies of romas are now hitting Nogales three weeks later than normal.

After a lot of cold weather, replantings, etc, the warm weather in Mexico is resulting in big volumes. However, the crappy wether continues in much of the US.

As spring approaches there also big volume with eggplant, vine ripe tomatoes, bell peppers and cucumbers.  This situation is expected to continue for at least another two months.

Mexican produce crossing the border at Nogales – grossing about $3600 to Chicago.
