Within the last week, there have been recalls of raw nuts and raw sprouts and raw sprout products due to the potential for Salmonella after those products were tested and found to be Salmonella positive. Surprising....not really. Makes you feel like that infant in the e-trade commercial feigning a sense of shock at a very predictable outcome.
Raw sprouts and raw nuts are a risk for pathogenic organisms like Salmonella. There are no significant pathogen reduction steps. And although some may suggest testing as a control, it is hit or miss when there are low levels of contamination - so testing as verification but not as control.
The Corrugated Packaging Alliance (CPA) sponsored a study that evaluated the impact of the corrugation process on bacterial pathogens. The study found that the high temperatures used (180 to 200ºF were sufficient to achieve a 5 log reduction of bacteria such as E. coli and Salmonella. We normally would not have considered corrugated boxes an issue, well, now here is the documented proof.

ITASCA, IL (FEBRUARY 2, 2016) – A new study shows the process of combining linerboard and medium to make corrugated packaging is sufficient to destroy common food pathogens, effectively meeting the U.S. Environmental Protection Agency’s (EPA) requirements for chemical sanitizers.
Maytag Dairy Farms expanded its recall to include additional lots of cheese that may be contaminated with Listeria. This initial recall, posted on February 14th, was expanded to one other lot on February 18th and then additional lots were added to the recall on February 19th.
Unfortunately, this issue, the expanding recall or recall creep, has been seen with other Listeria related recalls. It starts when a lot of product is recalled in reaction to a Listeria positive sample - it could be product or product contact sample. But once the regulatory folks start poking around, the realization comes that the company does not have a solid understanding of how well they are controlling Listeria. This is not to say they were not doing Listeria testing, but the testing program was not providing sufficient data to establish a sense of control.
On the other hand, there are examples of companies who have had recalls, but upon analysis of their faculties, the assessment is made that the positive sample was a aberration based on a solid Listeria control program (sanitation SSOPs, process control, and verification testing.)

The Canadian Food Inspection Agency (CFIA) announced that Freshpoint of Vancouver is recalling Del Monte and Sysco cantaloupes after the Agency tested and found positive Salmonella samples. There have been no injuries to date.
Whole Foods and Forever Foods are recalling Pecorino Aged Cheese wrapped in Walnut Leaves after Forever Foods completed testing and found the sample positive for Listeria.
A story on the web has raised an issue - wood in cheese, and this is resulting in more fear mongering than something for concern. The story states that there is wood in cheese and then uses a 2012 case of food fraud with cheese to make the point.
First, while cellulose is found in trees, it is also found in all plant tissue including fruits and vegetables. In cheese, powdered cellulose is used as an anti-clumping agent and is / should be declared on the label when used. In the end, grated cheese manufactures are not putting wood in cheese, it is powered cellulose, and this is 'generally recognized as safe' , or GRAS....but not grass (humor). Powdered cellulose is a good material for use as an anti-clumping agent in grated cheese - it provides stability of both the oil and water phases of the cheese.
According to the Bloomberg report, they tested a number of cheeses and found that some had higher levels of cellulose than the 2 to 4% that is normally used. As far as I can find, there is no established limit for powdered cellulose in cheese listed in the Code of Federal Regulations. In their investigation, some cheese samples were up to 7 or 8% cellulose. If true, that would be high, but this was not a scientific, peer reviewed study.
The 2012 case was that of a PA manufacturer of cheese who was using cheaper cheeses to make grated parmesan cheese. This is a no no. The manufacturer went out of the business in 2014 and according to reports, "Castle President Michelle Myrter is scheduled to plead guilty this month to criminal charges. She faces up to a year in prison and a $100,000 fine." This cheese is no longer on the market, so no need to rifle through your refrigerator in search of fake parmesan from this company.
No doubt, food fraud is a big issue. Olive oil is the poster child for food fraud. With cheese, hopefully manufacturers are using powdered cellulose prudently, but in the end, it is just fiber (pun intended...now that is humor). But if you are worried about it, the solution is easy...grind your own cheese. You will have a better product and you will save the earth from excess packaging.
An Iowa cheese maker is recalling its Raw Milk Blue Cheese after the Iowa Department of Ag discovered Listeria during routine testing. The facility is recalling on lot, produced on January 6th (over one month ago). There have been no reported illnesses.
An issue that can be seen in these cases is that when one lot is contaminated with Listeria, there is always a good chance that other lots can potentially be contaminated, especially if the facility does not have good environmental controls for Listeria in place.

Fareway of Newton had some blue cheese from lot; Hy-Vee did not

Maytag Dairy Farms of Newton announced a voluntary recall Saturday of an 896-pound of blue cheese due to possible listeria contamination.
The foodmaker announced lot number 150481 of Maytag Raw Milk Blue Cheese could be contaminated with Listeria monocytogenes. The recalled product was packaged on Jan. 6 and was then distributed to several locations in central Iowa.
A processor of 'high end' smoked seafood products was shut down for unsanitary conditions. This came after 'a decade' of issues. This facility's product was used by a number of notable restaurants and the facility had won some awards. (Company website).
Vacuum packaged smoked salmon is a pretty risky product if not done right. First, it can be a Clostridium botulinum risk if not properly processed, which was one of the issues according to reports.. Listeria is also a risk if it contaminates the product in the time after smoking and before packaging. The facility had that issue in the past which had resulted in a recall.
This seems to be a good brand to add to the 'do not eat' list.

Sullivan Harbor Farm in Hancock had been warned for more than a decade that its manufacturing of smoked salmon was unsanitary, the U.S. Justice Department says. BY BETH QUIMBY STAFF WRITER bquimby@pressherald.com | @QuimbyBeth | 207-791-6363
A high-end Hancock seafood company has been shut down for repeated unsanitary conditions and food safety violations, including manufacturing in the presence of rodent excrement, according to the U.S. Department of Justice.
