Improperly Canned Potatoes Responsible for Botulism Outbreak in April, 2015

In April of  2015, a botulism outbreak occurred that was associated with food served at a Church Potluck Meal.  In this outbreak, 29 reported becoming ill.  This was the largest botulism outbreak in the last 40 years.

The source was home canned potatoes.  The potatoes were canned in hot water bath and not a pressure canner.  From the CDC:
The attendee who prepared the potato salad with home-canned potatoes reported using a boiling water canner, which does not kill C. botulinum spores, rather than a pressure canner, which does eliminate spores (2). In addition, the potatoes were not heated after removal from the can, a step that can inactivate botulinum toxin. The combined evidence implicated potato salad prepared with improperly home-canned potatoes, a known vehicle for botulism (3).
Unfortunately, we hear of too many who still use a hot water bath to can low acid foods.  Outbreaks like this remind us of the importance of following scientifically developed canning recipes, especially the use of a pressure canner for low acid foods.

On April 21, 2015, the Fairfield Medical Center (FMC) and Fairfield Department of Health contacted the Ohio Department of Health (ODH) about a patient suspected of having botulism in Fairfield County, Ohio. Botulism is a severe, potentially fatal neuroparalytic illness.* A single case is a public health emergency, because it can signal an outbreak (1). Within 2 hours of health department notification, four more patients with similar clinical features arrived at FMC's emergency department. Later that afternoon, one patient died of respiratory failure shortly after arriving at the emergency department. All affected persons had eaten at the same widely attended church potluck meal on April 19. CDC's Strategic National Stockpile sent 50 doses of botulinum antitoxin to Ohio. FMC, the Fairfield Department of Health, ODH, and CDC rapidly responded to confirm the diagnosis, identify and treat additional patients, and determine the source.

Study - Pesticide Levels on Produce Well Below Level for Health Concern

In a recently published study in the Journal of Food Contamination, a UCDavis researcher found that pesticide levels in foods are far below the level of concern for the period 2004 - 2005.  2240 food items were evaluated and that "All estimated exposures to the 77 pesticides were well below the chronic reference dose (RfD) – the EPA’s estimate of the maximum amount of a substance that a person could be exposed to daily without risk of harm over a lifetime".

Takeaways - You can't use pesticides as a reason to avoid eating fruits and vegetables.  The health benefit far outweighs any risk. 
- The primary reason people buy organic produce is pesticides.  Based on this data, is the added cost of organic justified?

Consumer exposure to pesticide residue far below levels of health concern
Posted on July 16, 2015 by admin


A new study published in International Journal of Food Contamination shows that pesticide levels in food are far below levels that would warrant health concern.

The author of the study, Dr. Carl K. Winter of the Department of Food Science and Technology at the University of California – Davis, used FDA data on pesticide residue findings collected between 2004 and 2005 on 2,240 food items. A total of 77 pesticides were detected in the samples. (Dr. Winter is a member of ACSH’s Scientific Advisory Panel).

All estimated exposures to the 77 pesticides were well below the chronic reference dose (RfD) – the EPA’s estimate of the maximum amount of a substance that a person could be exposed to daily without risk of harm over a lifetime. As Ross Pomeroy at Real Clear Science notes, “These doses are extremely conservative, often inflated by two orders of magnitude to ensure consumer safety.”

Small Food Establishment Forced to Recall Improperly Processed Products

A small Washington establishment is recalling canned pickles and sauces after it was determined that the pH was too high.  The company was selling their product at fruit stands and small shops.

This is an example of the type of issue small businesses can run into when getting into producing foods when they do not know what they are doing.  Too many people want to make these type of products to sell at Farmers' Markets and roadside stands, but do not understand the importance of following the proper procedures for processing.  In this case, they had to recall product.  Worse, they could have made someone ill or worse.  Either way, issues like this can become a financial catastrophe for the establishment.

Penn State has begun a new training program to specifically address this need.  In Farmers' Market Food Safety Workshops, guidance is provided.  But this training opens the door to other training that is more specific to the operation and type of products being made.

Q&A: Food safety expert helps home cooks preserve produce properly By MARY ELLEN WRIGHT | Staff Writer LancasterOnline

Home canning — processing food for storage in glass jars — is a great way to keep a bit of summer on your shelf year-round by preserving fresh Lancaster County produce. But canning must be done safely.

That’s where Martha Zepp, an expert in food preservation safety, comes in.

As a consultant to the local Penn State Extension office at the Farm & Home Center, Zepp is available to answer your food safety and food preservation questions most Wednesdays (her day in the extension office). She also gives demonstration workshops on home canning and goes to canning-equipment stores around the county to test the dial gauges of people’s pressure canners to be sure they’re in proper working order.

Capturing summer in a jar: Home canning season in full swing here

She does all these things so home cooks can preserve food without accidentally encouraging the growth of botulism or other organisms that could make them sick.

We asked Zepp these questions about safety in home canning.

Aspen Foods Recalls Frozen, Raw, Stuffed & Breaded Chicken Products Due to Possible Salmonella Enteritidis Contamination
Class I Recall 101-2015
Health Risk: High Jul 15, 2015

WASHINGTON, July 15, 2015 – Aspen Foods, A Division of Koch Poultry Company, a Chicago, Ill. establishment, is recalling approximately 1,978,680 pounds of frozen, raw, stuffed and breaded chicken product that may be contaminated with Salmonella Enteritidis, the U.S. Department of Agriculture’s Food Safety and Inspection Service (FSIS) announced today.

The frozen, raw, stuffed and breaded chicken items were produced between April 15, 2015 and July 10, 2015 with “best if used by” dates between July 14, 2016 and October 10, 2016. To view a full list of recalled products, please click here (XLS). [View Labels]

Breaded Chicken Nuggets Recalled Due to Presence of Staph Enterotoxin

A PA company is recalling chicken nuggets after the CO Dept of Ag found that a sample of the product was positive for Staphylococcus enterotoxin.  There have not yet been any illnesses reported.

Staphylococcus growth and toxin formation is an issue in breaded/battered product. The main issue is with the hydrated batter before it goes onto the chicken.  In this scenario, the organism grows in the batter when the batter is not held at the proper temperatures.  When the organism reaches sufficient numbers, toxin is produced in the batter and then that toxin ends up on the food, in this case chicken piece, during the battering process.  In a typical batter operation, once the chicken is battered/breaded, then it is partially fried (par-fried) to set the coating.  This heat application (dipping in hot oil) kills the Staphylococcus organism, but does not destroy the toxin since the toxin is heat stable..

To prevent this, proper temperature control of the batter is needed.  FDA has recommended batter handling instructions (http://www.fda.gov/downloads/Food/GuidanceRegulation/UCM252424.pdf).
Another possible scenario is that that the chicken nugget product, once fried, is not cooled properly and the organism grows on the temperature abused nuggets.

Staphylococcus enterotoxin is fast acting, causing severe vomiting in an hour to 6 hours after consumption. The symptoms will last a day or so.  When it is a batter contamination issue as described above, there would be no indication to the consumer that the product was contaminated, and no prevention.  Again, cooking by the consumer would not destroy the toxin.

Food Safety Update for July 10, 2015

Avian Influenza Outbreak in birds has come to a halt with no new cases reported since June 17th.  It has been one of the most devastating outbreaks of bird flue with approximately 48 million birds affected.  According to reports, there is a lot of room for improvement in responding to such a serious outbreak.
In Texas, there are an increased number of illnesses due to the parasite Cyclospspora.  There have been 151 cases reported.  (Story/link below).
 
In North Carolina, one restaurant has been linked to 267 cases of salmonellosis.  Bad BBQ.  (Story/Link below)
 
In a recent study, it was found that farmers should wait for 24 hours after a rainfall or irrigating before harvesting.  The research was based upon the presence of Listeria.
   

Summary Data for Beef and Veal Carcass Baseline Survey

In USDA's Constituent Update, July 2, 2015,  FSIS provides a summary of preliminary data for the first six months of the Beef and Veal Carcass Baseline Survey (B-VCBS) that looks at the prevalence of Salmonella and E.coli on carcasses, - after removing the hide, and after cleaning the carcass (before it goes into the chiller - pre-chill).  FSIS is collecting swab samples from steers, cows, bulls, dairy cows, heifers, and veal carcasses in order to estimate the level of these organisms and to see whether  and to evaluate the pre-evisceration and pre-chill dressing procedures and slaughter controls.  From the document:


What do can be taken away from this:
1) The interventions used by the industry accomplish a big reduction in the level of pathogenic organisms on the meat.
2) Pathogens are present on the meat.  As pointed out in the release, additional interventions may occur after chilling,, so the number of percent positive purchased by the consumer will probably be lower (and have been shown to be lower).  However, consumers must still consider the fact that pathogens can be present.
