So the US BSE outbreak is not so much of a threat after all?
The US Department of Agriculture confirmed that a case of so-called mad cow disease had been found in California, in a dairy cow.
But no meat from the infected animal had entered the food chain, meaning exports should be unaffected.
Livestock investors themselves appeared cautiously satisfied, allowing Chicago's May feeder
And that helped Chicago crops, many of which are used in animal feed, revive too, with the grains and soybeans all pointing the same way, upwards, not something investors have been used to of late.
General market mood helped too, with
Shares in the technology group, which sold 35m iPhones and 11.8m iPads during the latest quarter, ahead of market estimates, soared 7% in after-the-bell trading.
Results from Credit Suisse, SAP and Siemens early on Wednesday also bolstered sentiment.
Indeed, the safe haven of the
But there were other reasons to buy crops too, with the focus remaining on the latest downgrades to the Argentine soybean crop, down to 42.5m tonnes by Oil World and 41.5m tonnes by Soybean and Corn Advisor.
The USDA has the figure at 45.0m tonnes.
"Some private analysts even bet on a production below 40m tonnes," Paris-based Agritel said, and the drought-hit drop after all faces fresh weather threats, from cold temperatures.
"The hard freeze that occurred in Argentina was centred in the lower two-thirds of the province of Buenos Aires," Brian Henry at Benson Quinn Commodities noted.
"Temperatures reached lows of 26-30 degrees Fahrenheit, which can cause damage to soybeans that are not mature," he said, adding that the freezes may not be the last.
At Market 1, Mike Mawdsley said it was "too early to know for sure" what damage the cold temperatures had caused so far.
"But old crop soybeans have certainly traded the news," he added.
Indeed, the May contract added 0.8% to $14.72 ½ a bushel, a fresh high for a spot contract since September 2008, with the better-traded July lot rising in line to $14.76 ½ a bushel.
November soybeans gained 0.4% to $13.57 ½ a bushel, making a late bid for further acres in US spring sowing plans.
The May lot added 0.2%, to $6.19 ¾ a bushel, with the July contract up 0.3% at $6.09 ¾ a bushel.
Sure, cold weather in the US represents a risk to rosy crop forecasts.
"In March it appeared as if corn planting would advance at a record early pace this spring, but cold temperatures in April are putting the brakes on," Gail Martell at Martell Crop Projections said, adding that sprouting would be "further hampered by the cold forecast this week in the Midwest".
However, corn futures have continued to feel pressure from disappointment over the relatively low levels of confirmations of corn sales to "unknown", believed to be China, compared with figures of up to 2m tonnes which have been in circulation.
Furthermore, Lynette Tan at Phillip Futures raised a question over the competitiveness of US export supplies, noting that "Taiwan bypassed the US and bought cheaper corn from Brazil".
Indeed, corn lagged fellow grain
With frost an issue for US wheat seedlings too, and even more so for winter crop in an unusually-developed state, wheat there "could be a choppy, whipsaw environment in wheat coming up", Mr Mawdsley said.
At PFGBest, Tim Hannagan said: "There's a couple of chances for frost damage Thursday and next Monday. Wheat traders are watching closely."
The positive feeling spilled over into soft commodities too, with New York
