Listeria and cheesemaking are often together

The New York Times reports this morning that listeria can pose special challenges for artisan cheesemakers. Many make their cheese right on the farm, where the bad bacteria are right outside the cheese room door (or inside – dp). And small producers often lack the safety training and resources available at bigger companies.

For example, Sharon McCool got a shock last year as she prepared to begin selling the first batch of cheese she had made from milk produced at her family’s organic dairy, Rosecrest Farm, in Chehalis, Wash. State inspectors told her the Swiss cheese she had labored over for months was contaminated with listeria.

Tests showed that the bacteria was contained in a mixture of wine, water and salt, called a smear, that Ms. McCool had been brushing on her cheese each day as it aged. Without knowing it, she was dosing the cheese with listeria.

Ms. McCool threw out 900 pounds of cheese, changed some of her practices, got rid of the smear and started over.

Ms. McCool and her husband, Gary, have for years operated a dairy, where sanitation is paramount, so she thought she was well versed in food safety. But she now sees that she had overlooked some obvious pitfalls.

Before, Ms. McCool said, she had been so proud of her new business that she had often showed visitors around, possibly introducing listeria through their shoes or clothing.

Now, visitors are kept out. “Pretty much everything is really a whole lot stricter,” Ms. McCool said.

The number of small-scale, artisan cheesemakers has boomed in recent years but little or no formal training is required. Safety rules and enforcement also vary from state to state.

Soft cheeses — including brie, mozzarella and queso fresco — are more likely to become contaminated with listeria because they have a relatively high moisture content and low acidity, creating a more hospitable environment for the bacteria. In addition, listeria grows well at low temperatures, so even it can thrive even in a refrigerator.

The F.D.A. said it is inspecting both raw-milk and pasteurized cheese facilities for listeria, and recalls this year have been for both types of cheeses.

The agency also said it was reviewing the aging rules in light of evidence that the 60-day period might not be effective.
 

Kimchi crackdown in Korea

The Korea Food and Drug Administration announced Friday that it conducted a joint inspection with local governments on kimchi producers and ingredient makers over a 2-week period earlier this month in order to ensure that consumers are free from foodborne illnesses.

Of more than 1,000 companies inspected, 140 were cited for having poor sanitary conditions or failing to conduct self-quality checks before selling the food products.

Kimchi is a traditional fermented Korean dish made of vegetables.

Raw egg in mousse, cows hazards to NZ health

Chocolate mousse cake made with raw egg whites sickened 21 people in two different groups in Sept. and Oct. in the Timaru district of New Zealand.

Another 21 cases of campylobacter were recorded in South Canterbury and 28 cases of cryptosporidiosis in the same time period, according to medical officer of health Dr Daniel Williams.

The Timaru Herald cited Dr. Williams as saying, "Many of these cases are people who live in rural areas and are associated with the dairy industry. Cryptosporidium is a microscopic parasite found in the gut of many animals both wild and domestic. People become infected when the parasites are swallowed. This may be from contaminated water or more usually from direct contact with infected animals. … Toddlers on farms are particularly at risk. Although it can be difficult, children should be supervised to prevent them swallowing infected material. The best protection for people who are in close contact with animals is thorough hand washing using plenty of soap, cleaning under finger nails, rinsing hands and drying on a clean towel."
 

French farmer kept ducks stoned to prevent worms; court says no

A 60-year-old duck farmer in France received a one-month suspended sentence and a 500 Euro fine after providing cannabis to his waterfowl.

During the hearing the farmer admitted that he also smoked "a little" marijuana and he justified giving it to his 150 ducks as a "purge." He said there is no better way to deworm the birds. He said was advised to do so, but would not name the specialist who gave the advice.

The farmer was caught after he reported a theft at his home in October. Police arrived to discover 12 marijuana plants and a 5 kilo bag of weed.

The police said this was the first time they have seen anything like this even though they are quite accustomed to hearing silly excuses when it comes to narcotics (or that’s how Amy translated that sentence; thanks to Albert for the story tip).

New food safety infosheet: holiday meal food safety

Thanksgiving is my favorite holiday. Mid-week football, four days of quiet family time and the kick-off of the holiday season — signified by the repeated showing of National Lampoon’s Christmas Vacation on USA Network. With a new little dude here (Sam, he was born Nov 6) who likes to feed every couple of hours and a somewhat crazy 2-year-old, most of the turkey dinner preparation is falling to me this year. I’m planning on doing some dishes in advance and cooking a simplified menu — but it will still involve a fresh turkey. Click here for the holiday meal food safety infosheet.

Zoo animals for dinner – Why not?

In a form of logic that only the Brits could come up with, The Independent argues that if a recent listeria-related recall of turkey breast and ham by a Texas firm is casting doubt on Thanksgiving plans, then why not go for exotic meats, like the deer and turkeys in my backyard in downtown Manhattan (Kansas).

Not quite sure how the editors at The Independent got to zoo animals in the headline.

Chef Dave Arnold, director of culinary technology at the International Culinary Center’s French Culinary Institute, blogs in a Nov. 8 blog entry written for Popular Science magazine’s Web site, that those who prefer tougher meat should enjoy wild game even more than standard meat and poultry, which he says are generally butchered young to ensure tenderness, and lack the flavor of their full-grown counterparts.

Arnold’s tastes are nothing new – during the Middle Ages, bear meat consumption was symbolic, and bear paws are still considered a delicacy in Cantonese cuisine. Beaver meat has been eaten by indigenous North American populations for generations.

Upscale Chicago eatery Moto served a road kill raccoon dish back in 2008, and this past June an Arizona restaurant owner caused a public uproar when he put lion burgers on his menu.

Exotic meats are generally avoided due to concerns over bacterial contamination and animal cruelty. However, in light of recent fears of listeriosis sparked by common meats found in neighborhood supermarkets, people may be more willing to step out of their comfort zones this Thanksgiving.

But no one got sick in the listeria positive recall cited in the story because at least someone was looking (in this case, U.S. Department of Agriculture’s Food Safety Inspection Service). And the public was warned. Recalls are not the same as outbreaks.

Dave Arnold’s Low-Temperature Game Cooking Notes

In all cases sear the meat first and put into Zip-loc bags with butter. Cook in an immersion circulator for the prescribed times, then sear again for a minute or two per side on high heat.

Yak: cook at 56°C for 24 hours. Rich and gamey, with notes of duck.

Lion: 57°C for 24 hours. Tastes like pork but richer.

Black bear: 57°C for 3 hours. Tastes a little bloody and metallic. Younger bears are reportedly better.

Beaver tail: 60°C for 48 hours. Woodsy, delicious.

Duck, and birds that cook like duck (teal, widgeon): 57-58°C for 45 minutes to an hour for the breast. Braise the legs.

Squab: 56°C for 45 minutes for the breast. Braise the leg.

Raccoon: I recommend cooking raccoon in a traditional braise.

No hot water, Grand China Restaurant closed

KTNV reports Grand China Restaurant on West Craig near Decatur in North Las Vegas was closed by inspectors after they discovered that the restaurant did not have any running hot water.

It usually takes more than 40 demerits to close a restaurant, but a situation such as this resulted in an automatic shutdown by the Southern Nevada Health District at 35 demerits.

And there were many other problems: a continuous leak from a kitchen sink that needed fixing; hand sinks being used for jobs other than hand washing; uncovered food found double-stacked; prepared food in the walk-in cooler improperly labeled and dated; and a tea bag wrongly attached to the spout of a hot water dispenser.

An inspector found an extremely filthy wok station, a dirty can opener, and an ice cream scoop left on a dirty surface. The floor was very dirty and, when inspectors looked at the ceiling, they found falling tiles due to excess water damage.

Channel 13 stopped by Grand China once the restaurant re-opened for business after re-inspection.

Tricia Kean: You had 35 demerits and a closure because you had no hot water. Is there a manager or owner here that I can talk to?

"No, nobody can talk here."
